This genus is well- mai-ked off from Pcecilia by the structure of 

 the intromittent organ (text- tig. 173 E). At some distance from 

 its end the first pi'oduced ray becomes abruptly slender ; the distal 

 part is not serrated, and near its extremity it bears an antrorse 

 spine ; the second and third produced rays are nearly as in 

 Pcecilia. As in Poecilia, the intromittent organ is short, usually 

 shorter than the head, and its extremity is protected anteriorly 

 by a cutaneous hood ; in fully adult males the second pelvic ray 

 is more or less prolonged. 



Of eight species seven are from Cuba, Haiti, and Jamaica, and 

 one from Venezuela. I have examined adult males in all but 

 L. ornata. 



Synopsis of the Species.
