space reaches to the middorsal line on P. matsubarai but is absent on 

 P. asteroides. 



From the other related species matsubarai may be distinguished by 

 use of the key to the species of Polyipnus on p. 621. 



Dr. Tamotsu Iwai writes that all of the specimens used in Mat- 

 subara's 1941 and 1950 reports were destroyed by fire. 



Since the accounts of Kuroda and of Oshima are in Japanese, Dr. 

 Matsubara has kindly translated them for me, as follows: 



Kuroda, N., 1935: On rare fishes contained in Suruga-Wan Marine Biological 

 Laboratory. Botony and Zoology 3(4): 830-831. 



Polyipnus stereope Jordan and Starks 

 Honen-eso (Japanese name) Sternoptychidae. 

 This is the famous luminous fish and the body is roundish in outline. It also 

 is called Honen-uo. Several specimens. 



Oshima, M., 1938: Preliminary report on the results of investigation of deep- 

 sea fishes obtained from Suruga Bay. Hattori Hokokai Kenkiu Shoroku, (5) : 

 281-285. 



Family Sternoptychidae 

 Polyipnus sterope Jordan and Starks, Honen-eso 

 Locality. Off Yaizu, Shizuoka, Pref., depth 100-200 m. The present species 

 has been ascertained as the new species by Jordan and Starks based upon three 

 specimens obtained from deep water of Sagami Bay. This species is very rare 

 and generally is considered difficult to obtain. Only single specimens have been 

 obtained together with luminous shrimps, but this is the new record from Suruga 

 Bay. 



Oshima misspelled P. stereope Jordan and Starks. 



This new species is named matsubarai in honor of my esteemed col- 

 league, Dr. Kiyomatsu Matsubara, who loaned the specimens for 

 study.

Polyipnus fraseri Fowler, Proc. Acad. Nat. Sci. Philadelphia, vol. 85, p. 257, fig. 

 19, 1934 (holotype USNM 92324, lat. 12°56'24" N., long. 124°25'24" E., 

 Albatross station 5476, and not as published by Fowler). — Schultz, Proc. U.S. 

 Nat. Mus., vol. 86, pp. 142, 145, 1938 (Philippines). 



Study material: Only known from the holotype. 



Distinctive characters: This species, along with japonicus, 

 has only four anal photophores, fewer than occur in any other species 

 in the genus. The posttemporal spine is long and strong, with two 

 shorter but strong spines arising basally, and the posterior bony 

 edges of both supracleithrum and preopercle are serrated. 



Description: Counts made are given in table 1, p. 591, and table 

 6, p. 636.

Range: This species is known from the Philippine Islands.
