2758. EMBLEMARIA OCULOCIRRIS, Jordan. 



Head 3f ; depth 6|. D. about 35; A. 25. Upper part of eyeball above 

 pupil (sclerotica) with a slender cirrus tipped with black, this nearly as 

 long as eye ; eye longer than snout, about 3f in head, the maxillary extend- 

 ing to below posterior part of pupil; snout sharper than in Emblemaria 

 nivipes, f eye; teeth small, rather sharp, directed backward; longest 

 dorsal spines as long as head ; pectorals 1 in head ; ventrals If, inserted 

 before pectorals. Color in spirits, brown, with traces of about 9 blackish 

 cross bars, which are separated on the back by whitish, quadrate inter- 

 spaces; a white spot at nape; some dusky below eye; dorsal dusky, the 

 pale bars of back extending on its base; anal dusky; ventrals blackish; 

 caudal pale, its tip black; pectorals pale. Gulf of California. Known 

 from 1 specimen, 14- inches long, from La Paz. It is shriveled and in poor 

 condition. It seems to be very close to Emblemaria nivipes, but differs in 

 the presence of an ocular cirrus, in the sharper snout, smaller mouth, and 

 dusky ventrals. The teeth seem rather more slender, but can not be 

 well examined, (oculus, eye; cirrus, filament.)
