pressed spines, 1 turning forward, the other backward over front of eye, 

 these spines concealed by the skin. Gill rakers short and thick, less than 

 4- pupil, 4 developed. Dorsal beginning at end of anterior third of pecto- 

 rals, longest ray 3^ in head ; pectorals 2 in head ; inner ventral filament 

 longest, 2 in head. Air bladder short and thick, with a foramen. ^Scales 

 very small, more or less imbricated on body; head naked. Opercle with 

 a sharp, partly concealed spine. Pseudobranchite present. Color pale 

 yellowish brown, silvery on belly and sides of head ; back with about 12 

 irregular dark cross bauds, the alternate ones being narrower and broken 

 up into spots, 2 before dorsal; a few scattered spots about as large as pupil 

 on sides, these most distinct about the shoulder ; dorsal pale, first rays 

 black, and with 3 or 4 other black blotches on upper part ; anal black, 

 margined with white; pectorals pale, axil dusky; caudal and posterior 

 part of anal pale ; chin pale. A single specimen obtained at Indefatigable 

 Island, Galapagos Archipelago. Length 4 inches, (indefatigabilis, tireless.) 



Otophidium indefatigabile, JORDAN <fc BOLLMAN, Proc. U. S. Nat. Mus. 1889, 172, Indefati- 

 gable Island, in the Galapagos Archipelago. (Type, No. 44393. Coll. Albatross.) 



2862. OTOPHIDIUM GALEOIDES (Gilbert). 



Head 5 in length ; depth 6. D. 125. Maxillary reaching beyond pupil, 

 2 in head; snout 4f ; eye 3|. Gill rakers short and broad, 4 of them 

 developed. Opercle ending in a sharp concealed spine. Outer teeth little 

 enlarged. Dorsal beginning over middle of pectorals, the nape equidis- 

 tant between front of dorsal and tip of snout. Caudal very short and 

 bluntly rounded, as in Chilara taylori, the rays not projecting beyond dor- 

 sal and anal ; pectorals If in head ; ventral filament ^ head. Scales as 

 in C. taylori, not at all imbricated, arranged with their long axes fre- 

 quently at right angles to each other; head naked. Color light olive, 

 without bars, a narrow dusky streak along base of dorsal, and a round 

 light spot at origin of dorsal; a series of small olive-brown spots along 

 lateral line, with a few scattering spots below it but none above; nape 

 and head without spots; vertical fins translucent; dorsal with a large 

 black blotch on tip of anterior rays, the fin behind this narrowly edged 

 with black, which does not surround the caudal ; anal with much silvery- 

 white pigment anteriorly 011 distal portion, becoming dusky behind; pec- 

 torals translucent, edged with white below; peritoneum, buccal, and gill 

 cavities white. Closely related to Otophidium indefatigabile, differing in 

 color, and in the much shorter head, smaller mouth, less imbricated scales, 

 the more posterior insertion of dorsal, and the absence of spines on head. 

 Air bladder not examined. Pseudobranchise present. Gulf of California.

Family CCIX. LYCODAPODID^E. 



Deep-sea fishes allied to the Fierasferidce, differing chiefly in the normal 

 position of the vent, which is remote from the head, and just before the
