* This name is proposed for the genus (or perhaps the sub-genus of Fundulus) typified by 

 Fundulus stelliferus Jordan MSS. characterized by the large dorsal fin, the origin of which is 

 directly over the origin of the anal, by the reduced number of branchiostegals (three or four) 

 and by peculiarities of coloration, the males being ornamented by bright orange spots, which 

 are represented in the females by olive dots or lines.
