JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 301 



Family CARAPID.E. 



{Fierasferidce) . 



350. Jordanicus sagamianus (Tanaka). 

 Misaki, No. 6070a. 



This specimen corresponds to the account of Carapus sagamianus, except 



that the anal is under the base of the pectorals. It corresponds closely to the 



figure given by Franz. The maxillary being bound in the skin of the head, the 



species should be referred to Jordanicus Gilbert (/. umbratilis from Hawaii), and 



not to Carapus {Fierasfer). 



Family OPHIDIID^. 



351. Otophidium asiro Jordan & Fowler. 



Several specimens from Misaki, No. 6189a-b. Only the original type hitherto 

 has been known. 



Fig. 78. Otophidium asiro Jordan & Fowler. (From Proc. U. S. N. M., Vol. XXV, p. 752). 



Snout 2.2 to 2.5 in maxillary, which is 2.25 in head; longest ventral filament 

 2 in head. Tip of caudal colorless in all cases, although the dorsal and anal are 

 broadly margined with black. 



Family AMMODYTID^. 



352. Ammodytes alascanus Cope. 



Yokohama, No. 6164a, not before known save from Bering Sea. 

 One specimen, larger in size than any of the common A. personatus. 

 D. 57, A. 30. Body-folds 160. Head 4.5; depth 11. It is slenderer than the 

 type of A. alascanus, which was from Unalaska. 



Family BROTULID^. 



353. Spectrunculus radcliffei gen. et sp. nov. (Plate XXXVII, fig. 3). 

 The new genus, Spectrunculus, may be thus defined: 



Ventrals 2-rayed; caudal present, continuous with dorsal and anal; pectorals 

 short, entire; ventrals each of two rays, fully joined, inserted under isthmus; mouth 

 terminal, inclined toward vertical; no barbel; snout with strong dorsal convexity, 

 leaving profile of head concave; teeth on premaxillaries and mandibles very minute;
