species and C. Maiim, if they are distinct, or whether either is properly 

 placed in Cyprinodon. The shape of the body approaches that of Lebias, 

 or Jenynsia.

Micromugil Gulia, 1861, Tent. Ichth. Melit., 11. 



Form moderately elongate, compressed, caudal pedicel deep. Crown flat- 

 tened. Snout short, blunt; chin steep. Mouth small, directed upward; 

 lower jaws longer, firmly united ; upper short, protractile. Teeth in a single 

 series in each jaw, compressed and broadened toward the crowns, tricuspid. 

 Gill membranes united, free from the isthmus. Branchiostegal rays five to 

 four. Dorsal fin originating in the posterior half of the length ; first ray 

 not enlarged. First ray of anal farther backward than that of dorsal; fin 

 not modified on the male. Ventrals small ; rays five to seven. Caudal 

 large, deep. Intestine short to medium. Rather smaller than Cyprinodon. 



Mediterranean region in Europe, Africa, and Asia Minor to India. 



It seems to have been the intention at first to name this genus Lebia. 

 That name being preoccupied the added "s " was adopted. In a number of 

 instances of the synonymy species of Cyprinodon were included.
