[23] REVIEW OF THE SCEENID2E. 365 



This species is known to us from its type, a large specimen taken in 

 the Gulf of California. The specimen — also from the Gulf— recorded by 

 Dr. Streets under the name squamipinnis, seems to belong to G. othonop- 

 terus. The species is closely related to G. squamipinnis, bnt we believe 

 it to be distinct.

Habitat. — Coasts of Brazil and Argentine Eepubiic. 



This strongly marked species much resembles the northern weak- 

 fish in coloration, but it is readily distinguished by the small number 

 of its dorsal rays. 



Our description is mainly taken from a specimen 18 inches long from 

 Buenos Ay res (434, M. C. Z.). Other specimens are in the museum from 

 Montevideo, Maldonado, and Buenos Ayres. 



10. CESTREUS OBLIQUATUS. 



Otolithus obliquatus (Valenciennes MSS.) Sauvage, Bull. Soc. Philom. Paris, Hi, 209, 



1879 (Martinique). 

 Cynoscion obliqua turn J ordau, Proc. TJ. S. Nat. Mus., 188G, 588 (name only). 



Habitat. — Martinique. 



This species is unknown to us. The increased number of dorsal 

 rays leads us to place it in the neighborhood of Gcstrens nothus, with 

 which species the scanty description agrees in most respects. G. nothus 

 has, however, not been recorded from the West Indies. 



The following is the account published by Dr. Sauvage : 



"Un Otolithe e"tiquet6 dans la collection du Museum Otolithus obliquatus de la main 

 de Valenciennes, n'est pas d6crit dans FHistoiro des Poissons. Voisiue de 1' Otolithus
