The pigment granules in the eyes of Planaria disappeared as a result of thiourea treatment, but the skin pigment was not affected. In the eye-spot of the regenerating head, a little amount of pigment granules was formed, but later the eye-spots became gradually decolorized. Daily renewal of thiourea solution was less effective in inducing depigmentation of the eyes than keeping animals in the same solution throughout the experiment.

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.
The present paper deals with Apus sinensis UENO (=A. numidicus var. sinensis UENO) inhabiting a temporary pond in the grounds of the Hoten Shrine in Mukden. The water of the pond was fed by an artesian well in its neighbourhood and was introduced for the first time in the beginning of June, 1937. The greatest depth of the water was about 30 cm on July 1st and the water was yellowish brown in color due to the dissolution of loess-like clay which forms the pond-basin. The temperature of the pond water on the afternoon of July 2nd was as high as 33℃, which nearly corresponds to the air-temperature at that time; the pH-values of the water were 6.6-7.1. This habitat seems therefore to be suitable for the propagation of the species which can endure a considerably higher temperature. Since the supply of water by the pump was stopped on July 22nd, the pond dried up on 24th of the same month. All the inhabitants, including Apus sinensis, Eocyzicus mongolianus, certain aquatic insects and tadpoles, exposed in consequence their dead bodies in air. On july 1st, 2nd and 13th there were collected total 362 individuals of Apus sinensis, 200 of which were measured and closely examined. 1. There is a marked difference in the form of the carapace between both sexes. The carapace is more strongly curved downward on both sides in the female than in the male, and the ratio of its median length to the total length of the body is also greater in the female than in the male. 2. The female is much more dark green in color than the male. 3. The number of somites uncovered by the carpace varies greatly, but it is usually greater in the male than in the female. 4. The number of the post-pedigerous somites is comparatively constant, 8-11 (average 9.4) in the male and 5-7 (average 6.6) in the female. 5. In the male the spinules on the ventral posterior margin of the telson and on the ventral surface of the caudal rami are scale-like in shape. 6. The caudal rami are mostly shorter in the male and longer in the female than the total length of the body. 7. The egg is spherical in shape, reddish brown in color, and is 0.4-0.5mm in diameter. The number of eggs carried in the egg-sac is from 73 to 186 in four females examined. 8. Two hundred and sixteen males were found among 362 individuals caught in the pond mentioned; the ratio of the male to the female is therefore 1.5:1.

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.
