Gonionarce, GILL, 1. c., (indica). 



Disk more or less rounded, not emarginate in front ; spiracles very 

 close to the eyes, their edges tuberculate or smooth ; mouth narrow, sur- 

 rounded by a circular fold of skin, which forms the frenum of the nasal 

 valve; teeth in quincunx, not occupying the whole of the jaw, most of 

 them visible when the mouth is closed. Tail about as long as disk ; sec- 

 ond dorsal larger than first. Warm seas; the species usually smaller 

 than the species of Torpedo, (vapiaj, numbness, an old name of the Tor- 

 pedo). 



112. NARCINE BRASILIENSIS, (Olfers). 



Disk oval or nearly circular, the snout broadly rounded, not exserted; 

 spiracles with roughened edges ; snout 4 in disk, twice interorbital 

 width; mouth If in preoral part of snout; tail If times length of disk; 

 second dorsal a little higher and a little longer than first. Color varia- 

 ble, a fact which has given rise to several nominal species; sometimes 

 nearly uniform dark brown (in deep water); sometimes marked above 

 with dark spots and dashes (umbrosa)', sometimes with a dark band 

 across head and dark spots elsewhere (corallina). West Indies and 

 Brazil, occasionally northward to Key West and Pensacola. L. 2 feet.

 lar; tail with 2 dorsal fins and with a fold on each side; nasal valves 

 confluent; teeth flat, the hinder edge angular; spiracles close behind 

 eyes. Two species in the Eastern Pacific; small electric rays resembling
