Description of a New Deep-Sea Fish of the Genus Rondeletia from Japan

Abstract

Thanks to the cooperation of Mr. Yasoji ENDÔ, a specimen of a rare deep-sea fish resembling Rondeletia bicolor GOODE & BEAN of the family Rondeletiidae has been received for study. The specimen was caught early in October, 1962, 30 miles off Kesen-numa, Miyagi Prefecture, by the “Tomoe-maru” (two-boat-type trawler), at a depth of 750m., and was preserved in formalin till February 7, 1963, when the red color of the buccal cavity and some other parts of the body still remained reminding the senior author of the colored plate given by BEEBE and of the reproduced plate published by HARRY of the “giant-mouthed orange skin”, Rondeletia bicolor. But close examination of the specimen has revealed that it represents a different species which is believed to be new to science. The authors take pleasure in expressing here their cordial thanks to Mr. ENDÔ for his cooperation.
