But for its enlarged preanals, would be comparable with 

 M. guichenoti, bxit on direct comparison its slenderer form, feebler 

 limbs, and entii-ely different physiognomy shew that its affinity to 

 guichenoti is by no means close. 



Heteropus vertebralis. 



Habit stout. Snout moderately short, rounded ; the length' 

 anterior to the fore leg is contained once or once and a seventh in 

 the distance between the limbs. Frontonasal broader than lonsr,,

 frontoparietal ; prefontals nearly in mutual contact or forming a 

 long intersuture ; interparietal distinct, moderately small ; four 

 supraoculars, first longer than the second ; seven supraciliaries ; 

 parietals forming an intersuture posteriorly ; fifth or sixth upper 

 labial subocular. Ear orifice smaller than palpebral disk, with a^ 

 complete fringe of small pointed lobules or only a few anteriorly.

 bicarinate and smallest. Digits moderate ; 23 lamellfe under the
