A new species of Bregmaceros (Gadiformes: Bregmacerotidae) from the eastern Pacific Ocean, with comments on B. atlanticus and B. japonicus.

A new species of Bregmaceros is described based on a series of specimens from the eastern Pacific Ocean from near the Hawaiian Islands eastward to the California Current region. The new species bears considerable similarity in body shape and pigmentation to other overall darkly pigmented species with moderately high anal-fin counts (5159 in B. moseri) and modified prehaemal anal-fin pterygiophores (B.

A new species of Polyipnus (Stomiiformes: Sternoptychidae) from the Western South Pacific.

A new species of marine hatchetfish, Polyipnus laruei sp. nov., is described based on one specimen collected off New Caledonia, in the Western South Pacific.

A new species of Polyipnus (Teleostei: Stomiiformes) from the western Pacific, with comments on the P. triphanos species complex.

A new species of the teleostean family Sternoptychidae, Polyipnus notatus n. sp., is described based on material collected mainly off Taiwan in the South China Sea.

FEEDING STRUCTURES, BEHAVIOR, AND MICROHABITAT OF ECHINOCYAMUS PUSILLUS (ECHINOIDEA: CLYPEASTEROIDA).

In the Firth of Lorne, Scotland, Echinocyamus pusillus was found most abundantly in highly variable, poorly sorted substrates at depths of 10-20 m. It was common in areas exposed to extensive wave and tidal current activity, but absent in fine sediments in sheltered areas. In size, feeding mechanism, and behavior, the species is highly adapted for nestling in the interstices between relatively large pebbles.
