DESCRIPTION OF A NEW EHBIOTO€OII> FISH (C VMATOOASTEK 



UOSAC'EITS), FKOM THE COAST OF CAI>IFOKNflA. 



By S>AVIE> S. J©S£K>AN asid CMARS.ES Iff. GBLBEKT. 



Body rather elongate, deepest at the shoulders ; the protile thence to 

 the occiput convex, the occipital and interorbital region considerablj^ 

 depressed ; body tapering backwards from the shoulders into a short 

 and slender caudal peduncle. 



Head small, thick, the snout blunt. Mouth rather large, little oblique, 

 the lower jaw included; maxillary slightly passing the vertical from the 

 front of the orbit ; premaxillary anteriorly on a level with the inferior 

 margin of the pupil. Eye very large, its diameter about one-third the 

 length of the head ; interorbital region very broad. Lower lip with a 

 narrow frenum, above which its margin is narrowly free. 



Teeth large, in a single row, much as in Cymatogaster frenatus, but 



blunter, slightly compressed and truncate at tip, somewhat incisor-like, 



12 

 the edge, however, entire. Teeth few and distant, about -^ ; none on 



b 



the sides of the lower jaw. They are larger, blunter, and more wide-set 

 than in Cymatogaster aggregatus. 



Scales on the cheeks in three series below. 



Gill- rakers small and weak, much as in Cymatogaster aggregatus, curved 

 and apparently smooth. 



Scales large, but rather smaller than in any of the related species, 50 

 in the course of the lateral line. 



Spinous dorsal high ; the first spine two fifths the length of the highest; 

 the sixth to tenth of nearly equal height, and higher than the soft rays. 

 Anal fin with the base oblique and convex, the spines rather strong, more 

 or less curved, as in Abeona.
