FISHES OF SINALOA. 429 



of spots below the lateral line, these spots decrease in size 

 towards the belly, covering both sides nearly to level of 

 pectoral. 



Types, 1720, L. S. Jr. Univ. Mus. ; the largest 24 

 inches long. 



P^amily CARANGIDyE. 



79. Oligoplites altus (Giinther). Monda. 



One large specimen taken by us. Recorded by Dr. 

 Gilbert from Mazatlan and Panama. 



80. Oligoplites saurus (Bloch & Schneider). Monda. 

 Common in the harbor of Mazatlan, where it was also 



taken by Gilbert. On comparison of specimens from 

 Mazatlan with others from Havana we are unable to find 

 any difference whatever. The species called inornatus 

 is therefore fully identical with saui'us. 



81. Trachurops crumenophthalmus (Bloch). 

 Common in the harbor at Mazatlan, where numerous 



specimens were taken; not recorded by Dr. Gilbert. 

 Specimens have been compared with others from Havana 

 and no difference of any kind is observable. Trachurofs 

 brachychirus must therefore be regarded as an exact syn- 

 onym of Trachuro-ps criiinenophthalnius. 



82. Caranx vinctus Jordan & Gilbert. 



Rather common in the estuary, where numerous speci- 

 mens were taken. The original types were found by 

 Gilbert at Mazatlan, and the species has been recorded 

 from San Bias and Punta Arenas. 



83. Caranx caballus Giinther. Cojinero. 

 Extremely common in the harbor; also found in abun- 

 dance by Dr. Gilbert.
