tarsal fold. The hind limb being carried forwards along the body,

beneath immaculate. Male with a subgular vocal sac.

Differs from B. peltocephalus in the existence of an additional 
superficial arch of the skull, which passes from the mastoid region 
behind the auricular meatus, thus enclosing the latter, and causing 
it to be a mere foramen perforating a shield of bone. Tympanum 
small, only one fourth or one third the length of the palpebral 
border in diameter ; parotoid small, rounded, lateral.

Cranopsis fastidiosus, Cope, Jowrn, Ac. Philad. (n. 8.) viii. part 2, 
P00; Plazes. fA: 
Cranial integument entirely occupied by a rugose ossification ; 
cranial ridges consisting of elevated canthus rostralis, supra- and 
postorbital border, and a supratympanic crest extending to the 
parotoid gland; these, especially the last, are obtusely thickened ; 
supratympanic crest produced downwards behind the orbit as a 
rugose osseous plate to opposite the inferior border of the eye, 
bounding the position usually occupied by the membranum tympani 
by a rough concave margin; no tympanum. Fingers short; toes 
half webbed; metatarsal tubercles indistinct ; no tarsal fold. The 
hind limb being carried forwards along the body, the end of the 
longest toe reaches the end of the snout. Parotoids short, subtri- 
angular, as deep as long; upper surfaces of body and limbs studded 
with round warts, so closely on the latter region as to resemble a 
pustular disease. Yellowish brown aboye ; a blackish band extends 
from the parotoid to the axilla; top of head yellow or brownish 
yellow ; throat with a black spot.
