The retina of the dorsal eye consists essentially of a single visual cell layer with nervous process. In each visual cell the proximal and distal segments seem to be distinguishable. A distal segment corresponding to the outer segment of the rod contains several laminar cores (ellipsoidal or spherical in shape). Each laminar core has a granule-rich body at the center and joins to the cytoplasm of the proximal segment through a connecting piece. A cilium-like structure consisting of nine peripheral double tubules runs through a connecting piece. The proximal segment contains numerous mitochondria, a paranucleus and a nucleus. The important fact is that these structures are fundamental for the photoreceptors not only in vertebrates but also in molluscs.

The Japanese pill milliped, Hyleoglomeris stuxbergi, showed photo-orthokinetic, thermoorthokinetic and photo-klinokinetic responses under various light and temperature conditions. Although this species is nocturnal (Fig. 5-9), over-all activity was stimulated by light (10-2000lux) (Fig. 1-3) and higher temperature (5-41℃) (Fig. 4). But this contradiction is easily explained when the 15 patterns of responses of this species were classified in two categories of positive (favorable) and negative (fugitive) ones (Table 1). The enhancement of activity under a brighter condition was largely due to a decrease of positive response as virtual inactivity. Negative responses as vigilance and defensive responses also increased under the light (Table 2 and Fig. 8). This milliped is nocturnal because it shows negative response in the daytime and positive response in the night.

Deficiencies and surplus eruptions in the teeth of raccoon-dogs were examined using 340 specimens collected mainly from three localities in western Japan. Abnormalities in the dentition occurred in 26% of 308 perfect skulls. On the upper jaw, 9 examples of pm-1 deficiencies on both sides occurred, 8 on left side alone and 4 on right side alone among 317 specimens. There were no significant differences between the sexes, but differences did exist among localities. There were i-1, i-2, i-3, pm-2 and m-2 deficiencies, and i-surplus eruptions in some specimens. On the lower jaw, m-3 deficiencies occurred more frequently. Incidences of deficiencies on both sides, left and right side alone were 19, 19 and 15 respectively among 314 specimens. No significant difference was found between sexes and among localities. Other deficiencies were observed on i, pm-1, pm-2, pm-3 and pm-4. One surplus eruption occurred between c and pm-1. In one specimen, pm-4 duplications in the buccolingual direction were observed on both sides.

This paper deals with the seasonal variation of sex ratio, body weight, number of pregnant females and testicle size in the vole, Microtus montebelli. They were collected in the period from May, 1964 to September, 1965 in the montane zone (alt. 1,400-1,500m) on Mt. Yatsugatake in Honshu. The total number of specimens collected was 335. They are 33 Apodemus speciosus, 5 Apodemus argenteus, 272 Microtus montebelli, 22 Urotrichus talpodes and 3 Sorex shinto. Microtus montebelli was found exclusively in the grassy area of the montane zone. The number of female Microtus montebelli was larger than the males through months except for the months of May and October. Histograms of the body weight tend to indicate that voles grow rapidly in spring and reach maturity in months ranging from May to August. Breeding ceases in September, since the parent generation is rapidly dying off by October and completely so by November. The young generation comes into population from June and predominates in October, and extends through winter without coming into breeding condition. The life span of the vole may be more or less than 1.5 years. Pregnant females were obtained from May to November. The maximum monthly pregnancy rate occurred in June. The average number of embryos was 3.5. The monthly average testicle size increases and generally shows a maximum after winter. The testicle size was quickly reduced in September.

Bathysmatophorus J. Sahlberg, 1871, is a Palaearctic genus having been represented by a single boreal species, B. reuteri J. Sahlberg, 1871, and it is closely related to the Nearctic genus, Thatuna Oman, 1938, which was established by Dr. P. Oman with the following note and description:-"I am not familiar with B. reuteri and my concept of the genus is based upon the original description and Fieber's illustrations. Thatuna differs from Bathysmatophorus in the venation of the fore wing, which has the outer anteapical cell small and triangular and the central anteapical cell usually open baselly" [Proc. U. S. Nat. Mus. 85: 176]. Although the venation of Bathysmatophorus is so irregular that no definite generic diagnosis has been found in it, the genotype, Thatuna gilletti oman, 1938, has the appendix comparatively small and has the well developed subapical apophyses in the aedeagus which are not found in any known species of Bathysmatophorus [Oman, 1938, loc. cit. 177 pl. 6, f. 14]. Judging from these characters, Thatuna may deserve to be segregated from Bathysmatophorus and therefore the latter should be considered a genus distributed in the Palaearctic region. I described in this paper following two new japanese species of the genus, no species of which had hitherto been recorded from Japan. All the type-specimens dealt with in this paper are preserved in the Entomological Laboratory, College of Agriculture, Ehime University, Matsuyama. 1.Bathysmatophorus linnavuorii sp. nov. (Fig. 1, 1; Fig. 2, 1) Length of body ♂6.3-7, ♀8-10mm. Id. till the apices of tegmina ♂ about 7.8mm. Tegmen ♂6.3-7, ♀(brachypterous f.) 3-4.3mm. Weakly lustrous, mostly light blackish brown, with blackish markings as shown in figures. Habitat: Hokkaido (Mt. Daisetsu and its ranges). Specimens examined: Holotype (♂), allotopotype (♀) and 4 paratopotypes (3♂♂, 1♀), Kurodake, Mt. Daisetsu, 18-19, VII, 1951, T. Ishihara et K. Sasaki leg. 1 paratype (♂), Sounkyo at the foot of Mt. Daisetsu, 7. VII. 1951, Shizuo Kato leg. Although this new species is closely related to B. reuteri in the general appearance, the former is distinguished from the latter by the following characters. The body is bigger and robuster. The microsculpturing of vertex and of pronotum is more distinct and therefore this species is somewhat duller than B. reuteri. The plates are a little broader, with the median margin more insinuated near apex. The apophysis of style is much dissimilar. The trivial name is dedicated to Mr. R. Linnavuori, to whom I am indebted for obtaining the generic concept that the above related characters differ from those of European species. 2.B. japonicus sp. nov.(Fig. 1, 2; Fig. 2, 2). ♂ Length of body 6-6.2, id. till the apices of tegmina about 8, tegmen 6.3-6.6mm. ♀. Unknown. Mostly shining black, with light brownish markings as shown in the figures. Habitat: Honshu (Fukushima Prefecture and Niigata Pref.). Specimens examined: Holotype (♂) and 2 paratopotypes (2♂♂), Higashiyama, Kita-Aizugun, Fukushima Pref. 29. V. 1949, the late Koichi Nagayama leg. 1 paratype (♂), Miomote, Niigate Pref. 30. V. 1956, Kintaro Baba leg. The present new species may be easily identified by the characteristic coloration entirely different from other known species of the genus. The internal characters of the male genitalia rather resemble those of B. reuteri but the aedeagus of this species is constricted in the basal portion, being wanting of the apophysis placed dorso-basally and has the comparatively short distal portion recurved cephalad.
