Three other specimens, the fin-rays of which were counted, had respect- 

 ively D. 95, A. 72 ; D. 93, A. 70, and D. 98. 



Girard gives the number of dorsal rays as 82, while none of the 

 specimens which I have examined have less than 92. As the range in 

 number of dorsal and anal fin-rays is considerable in the individuals I 

 have examined, it is quite possible that some may have as few as 82 

 dorsal rays ; but the close agreement in the number of anal rays found 

 by Girard and by myself leads me to supi)Ose that the number 82 is a 

 typographical error. 



This is a tolerably common species in our markets, but is usually 

 taken outside of the bay. I have not yet seen any exceeding 12-14 

 inches in length. 



From Xo. 5 was taken a specimen of Engraulis ringens, which it had 

 only partially swallowed when caught ; the tail hanging out of the mouth. 



The Engraulis thus appears to be a favorite article of food with at 

 least three of our large-mouthed fiat-fishes. This species may be readily 

 recognized by its sinistral coloration and eyes, its smooth scales, dirty 

 yellow color, and the gradual tapering of the body into the caudal peduncle, 

 with a concave curve on both dorsal and abdominal outlines. Unlike 

 Flatichthys steUatits and Paralichthys maculosus, this species appears to 

 be invariably sinistral. 



GLYPTOCEPHALUS Gottsche. 

 Form extremely elongated ; mouth small, the short, narrow maxillary 

 scarcely reaching the front margin of the eye; teeth most developed on 

 the blind side, incisor-like, broad, equal, forming a continuous cutting 

 edge. !N"o vomerine or palatine teeth. Upper pharyngeal bones each 

 with an obliquely transverse row of about nine bluntly conical teeth; 

 lower pharyngeals with a single row of similar teeth. Brauchiostegals 

 seven. Eyes and color on the right side. - Anterior nostrils with a short
