4. Nototrema longipes. (Plate XXV II.) 



Tongue subcircular, nicked and free behind. Vomerine teeth in 

 two- straight series between the ehoanse. Head moderate, broader 

 than long; fronto-parietals strongly ossified, rugose, pitted or ver- 

 miculated, not confluent with the derm of the head ; snout elevated, 

 the tip obliquely truncate from nostril to lip, much longer than the 

 diameter of the eye ; loreal region slightly concave ; canthus rostralis 

 angular ; interorbital space not concave, broader than the upper 

 eyelid ; tympanum moderately distinct, about half the diameter of 

 the eye. Three outer fingers one-fourth webbed ; toes nearly 

 entirely webbed ; disks as large as the tympanum ; subarticular 

 tubercles moderate. The hind limb being carried forwards along 

 the body, the tibio-tarsal articulation reaches beyond the tip of the 

 snout. Skin smooth above, granulate beneath ; heel with a very 

 short dermal spur ; a small conical tubercle near the edge of the 

 upper eyelid. Yellowish above ; female minutely speckled with 

 brown on the back ; male with a broad brown cross band between 

 the eyes, a line from the eye to the vertical of the axilla, and five 

 spots of the same colour on the back — these markings formed by 

 the aggregation of dark-brown dots ; a brown, white-edged line 

 along the outer edge of the tarsus and fifth toe, and another trans- 

 versely above the vent. Prom snout to vent 82 millim.

Tongue subcircular, entire and slightly free behind. Vomerine 

 teeth in two short straight series on a level with the hinder edge of 

 the ehoanse. Head moderate, a little broader than long, forming a 

 rugose casque, the derm being involved in the cranial ossification ; 

 posterior border of casque, supratympanic, supraorbital, and cauthal 

 ridges with erect spines ; snout rounded, scarcely longer than the 

 diameter of the orbit ; loreal region and crown concave ; interorbital 

 space broader than the upper eyelid ; • tympanum very distinct, 

 nearly as large as the eye. Fingers webbed at the base ; toes 

 short, half webbed ; disks well developed, but much smaller than 

 the tympanum ; subarticular tubercles moderate ; a slight fold along 

 the inner edge of the tarsus. The hind limb being carried forwards 

 along the body, the tibio-tarsal articulation reaches between the eye 

 and the tip of the snout. Skin smooth above, granulate beneath.
