331. COLOLABIS, Gill. 



Cololabis, GILL, new genus, (breviroslris). 



This genus is close to Scombresox, differing chiefly in the very short 

 beak, the upper jaw, even in the adult, not being at all produced, and 

 the lower jaw having only a short flexible tip. This genus represents the 

 immature state of Scombresox. (/co/lof, defective, curtailed; "kafiig, forceps.) 



1076. COLOLABIS BREVIROSTRIS (Peters). 



Head 5i; depth 9. D. 9-VI; A. 12-VIj scales 125. Body much elon- 

 gate, compressed, widest above, the abdomen and lower edge of head 

 trenchant. Upper jaw conical, not at all produced, but ending in a very 

 acute tip ; lower jaw slightly longer, its tip produced for a very slight 

 distance, and flexible; triangular portion of premaxillaries as long as 

 broad ; snout a little more than half length of rest of head ; interorbital 

 space flat ; maxillary reaching front of orbit. Teeth very minute, in a 

 single row in each jaw. Eye large, in front of middle of head. Pectoral 

 fin somewhat emarginate, i length of head; ventrals small, far back, 

 slightly nearer tip of snout than tip of lower lobe of caudal ; dorsal 

 inserted slightly behind front of anal; both fins low, the finlets small; 

 caudal widely forked, the lobes equal. Scales small, deciduous, those on 

 top of head forming an elliptical patch. Dark green above, silvery below ; 

 sides with a lateral silvery stripe, bounded above by a dusky streak ; upper 

 fins mostly dusky ; lower pale. Length 14 inches. Coast of California ; 

 very rare. Known from Tomales Bay, San Francisco, and San Diego; a 

 most interesting fish, apparently closely related to a Japanese species, 

 Cololabis saira (Brevoort). (brevis, short; rostrum, snout.)
