532 On the Genus Lepidobatrachus, Budyett. 
might think the absence of vomerine teeth and the presence 
of “ two large teeth in dentaries of lower jaw” in the former 
sufficienf ground for generic separation, but both these 
statements are incorrect. Vomerine teeth are present, 
forming two small groups between the choanz, and the 
supposed teeth in the lower jaw are simply bony processes at 
the symphysis such as are known in several species of Rana 
and Ceratophrys. The teeth in the upper jaw are consider- 
ably larger than usual, but the same is the case in Cerato- 
phrys ornata, Rana adspersa, aud 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 Lepidobutrachus levis might be the 
same species as his L. asper, but I have no doubt the two 
are perfectly distinct, as may be seen from the following 
notes :— 
Ceratophrys aspera, 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 choane ; 
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 
us broad as the upper eyelid; tympanum moderately distinct, 
as Jarge as the eye, from which it is two diameters distant. 
Fingers rather slender, pointed, without subarticular tu- 
bercies, first shorter than second. Hind limb very short, as 
long as or slightly longer than head and body ; tibia shorter 
than the foot, 34 times in length from snout to vent ; toes 
short, pointed, half-webbed, without subarticular tubercles ; 
a narrow tarsal fold and a very large oblique, compressed, 
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
