532 On the Genus Lepidobatraclius, Budyett. 



m\"\\t think the absence of vomerine toetli and the presence 

 of " two large teeth in dentarit-s oh' lower jaw "' in the former 

 sufficient ground for generic separation, but both these 

 statements are incorrect. Vomerine teeth are present, 

 forming two small groups between the choanse, and the 

 supposed teeth in the lower jaw are simply bony processes at 

 tlie symphysis such as are known in several S[)ecies of liana 

 and Ceratophrys. The teeth in the upper jaw are consider- 

 ably larger than usual, but the same is the ease in Cerato- 

 jj/irys oruata, Rana adspersa^ and other Frogs with biting 

 propensities. " Fontanelles in the parietal region" seems 

 in contradiction with the '' great development of membrane 

 bones in the head '' ; I am unable to explain what the author 

 had in view. 



Budgett thought his Lepidohutrachus lavis might be the 

 same species as his L. asper, Ijut 1 have no doubt the two 

 are perfectly distinct, as may be seen from the following 

 notes : — 



Ceratophrys asper a, Budg. 



Tongue a little broader than long, entire, moderately free 

 behind, with a round central papillose area. Vomerine 

 teeth in two small rounded groups between the choame ; 

 maxillary teeth large ; a pair of large, acutely pointed tooth- 

 like processes at the symphysis of the lower jaw. Habit 

 very stout, arm and thigh enclosed in the integument of the 

 body. Head very convex, much broader than long; a rough 

 bony casque surrounding the orbits ; snout rounded, profile 

 descending abruptly from the nostrils to the mouth; nostrils 

 close together, 3 times as distant from the tip of the snout 

 as from the eye ; latter small, its diameter one-half its 

 distance from the mouth ; interorbital space concave, nearly 

 as broad as the upper eyelid ; tympanum moderately distinct, 

 as large as the eye, from which it is two diameters distant. 

 Fingers rather slender, pointed, without subarticular tu- 

 bercles, first shorter than second. Hind limb very short, as 

 long as or slightly longer than head and body ; tibia shorter 

 than the foot, 3^ times in length from snout to vent ; toes 

 short, pointed, half-webbed, without subarticular tubercles ; 

 a narrow tarsal fold and a very large oblique, compres-sed, 

 sharp-edged inner metatarsal tubercle, the length of which 

 is much greater than that of the inner toe. Upper parts 

 with numerous small warts of unequal size ; a narrow, 

 spindle-shaped, granulate dermal bone, about half the length 

 of the head, at a short distance from the latter, above the
