A new subspecies of the least red-toothed shrew, Sorex minutissimus ZIMMERMANN, 1780,is described from Korea under the name of S. m. ishikawai. It is the largest subspecies of the species, and seems closest to the Hokkaido subspecies, S. m. hawkeri THOMAS, 1906.

A minute caenogastropod snail, Amphithalamus (Amphithalamus) fulcira (LASERON, 1956) was recorded for the first time from the tropical to temperate regions of Japanese waters. The shell, radula and external morphology of the soft part were described in detail, and the distribution of the species in the Japanese waters was demonstrated. This is the first record of the family Anabathronidae not only from the Japanese waters, but also from the Northwest Pacific.

Juveniles of a rare callanthiid fish genus Grammatonotus are described based on six specimens (18.6-22.8 mm SL) from Tosa Bay, Pacific coast off Shikoku Island, Japan; the occurrence represents the first record of Grammatonotus juveniles from the northern Pacific. Although we could not determine their certain species name, they were most probably identical with G. surugaensis, based on geographic distribution and osteological characters. The characters useful for identification of the juveniles of Grammatonotus are discussed with other Grammatonotus juvenile specimens from other areas.

A specimen of a remarkable triggerfish (Balistidae) was found in the stomach contents of the marlinfish Makaira mazara (Istiophoridae) collected from off the Marianas Islands on July 9,1960. It is readily distinguishable from all other balistids by having great protuberances just below the pectoral fins. Since this unusual cahracter is not found in any other balistid, a dissection was made to ascertain if this specimen had any unique internal characters. Although the viscera of the specimen were completely digested by the stomach of M. mazara, the skeleton was still in good condition and shows uniqueness in the pectoral girdle, skull and the first dorsal fin. Thus, the specimen is here described as a new genus and species under the name of Xenobalistes tumidipectoris. The holotype, only known specimen, is deposited in the fish collection of the National Science Museum, Tokyo (NSMT-P).

To improve knowledge of school structure of killer whale, Orcinus orca (LINNAEUS, 1758), the composition of 18 schools (705 individuals in total) were analyzed from the sighting information obtained through a 57-day sighting survey in the Southern Ocean between 115°E and 160°W. The fundamental units of the school of killer whales are considered to be the single adult male, the adult female with calf, and other whales including the juvenile whale and/or the adult female without calf. An aggregation of schools seems to be formed by combination of several large schools, each of which has some unit schools.

A new nematode belonging to the family Physalopteridae was obtained from a primitive, deep-sea frill shark, Chlamydoselachus anguineus, caught off the Pacific coast of central Honshu, the main island of Japan. On the other hand, the larva was also found lying on the brain of a deep-sea bristlemouth, Cyclothone atraria, taken from the Pacific coast of northern Honshu. The life cycle of this nematode is briefly speculated. The nematodes were preserved in 70% ethanol and cleared in glycerin or Gater's solution. The specimens are deposited in the collection of the National Science Museum (Nat. Hist.), Tokyo. We are grateful to Dr. Toru TANIUCHI, Faculty of Agriculture, University of Tokyo, who afforded an opportunity to collect the parasites of the frill shark. Thanks are also due to Dr. Elmer R. NOBLE, University of California, and Dr. Yuzo KOMAKI, Far Seas Fisheries Research Laboratory, for providing valuable specimens.

The identity of the poorly known Philippine freshwater crab, Telphusa cumingii, is clarified on re-examination of the type in the British Museum. The species, briefly described by MIERS in 1884 and never reported since, has been regarded as belonging to the superfamily Gecarcinucoidea, and allied to species like Sundathelphusa picta and Holthuisana transversa. Telphusa cumingii in fact, belongs to the superfamily Potamoidea, family Potamidae, in the recently established genus Ovitamon NG et TAKEDA, 1992.

A new spider of the genus Xysticus C. L. KOCH, 1835,is described from the mountainous areas of Taiwan 1,500-3,300m in elevation, under the name of Xysticus chui. At present, this is the only species of the genus recorded from the island. Though its male palp appears unique in bearing three, much developed tegular apophyses, it seems to belong to the species-group of Xysticus luctans.
