Florida. 

 Length of head two and a half times in the total ; tympanic disk a ver- 

 tical oval ; dorsal spots well separated ; nostril equidistant between end 

 of muzzle and eye. 



This singular form may be known at once by the short and squat form 

 of the body as compared with the size of the head, resembling in this 

 some of the Australian Cystignathidae. 



The muzzle is not prominent, and does not project beyond the upper 

 lip. The canthus rostrales are straight, and the top of the head is flat. 

 The tympanic disk is a vertical oval, of which the short diameter is one 

 half the length of the eye. The edge of the vomerine patches of teeth 



* The determination of the relations between the North American and Euro- 

 pean species of this genus have been greatly facilitated by the admirable re- 

 searches of Boulenger.
