FISHES FROM GUAYMAS EVKRMANN AND JENKINS. 



A full description is ^iveii by Joidaa & Gilbert {op. cit.). In our 

 specimens (113, 137, and 170 iiiillinietres long respectively) the eye is 

 greater than the interoibital width, and the conical teeth of the lower 

 jaw are smaller than those of the upper jaw. 



This species is, curiously enough, confounded by the Guaymas fisher- 

 men with Roplopagrus guntheri under the name Fargo Raiscro. 



60. Orthopristis iiiornatus (Gill). 



Microlepidotus inornatus Gill, Proc. Acad. Nat. Sci. Pliila. 1862. 25G {Cape San Lucax).

Head, 3.3 in length of body to the base of the caudal ; depth of body 

 3.1. 



Dorsal fin, XIII, 1-15; anal fin, 111-12; scales, 9-78-20. 



Color in alcohol : steel blue, with metallic reflections above, lighter

Body stout, compressed posteriorly, deepest at about below the fourth

The maxillary slip[»ing under the preorbital for its whole length and 

 just reaching the verticiil I'rom the anterior margin of the orbit. 



Teeth in both jaws ; bands of niinute teeth, with the outer series pro- 

 jecting slightly. No teeth on vomer or palatines. 



Gill rakers on the anterior arch 8-1(5, slender, one-third the diameter
