Barboui — New Lizardsand New Toad from Dutch East Indies. 2\ 



much more developed; a continuous dorsal and nuchal crest of very 

 elongate, falciform spines; a large tympanum, the vertical diameter of 

 which is contained only one and one-third times in the distance from the 

 anterior border of the eye to the nostril; and a head of fundamentally 

 different shape, larger than in //. amboinensis, and its elongate form 

 reminds one of this species. The head is, however, longer in specimens 

 of the same size, and the snout is declivitous, which gives it a more 

 acuminate appearance There are many groups of a considerable number 

 each of enlarged plate-like scales on the side. In this character II. weberi 

 is intermediate between II. amboinensis and H. pustulosus. 



The type of the new toad which forms the last notice of this papier was 

 taken under an upturned stone on the road between Ampenan and 

 Mataram, on the island of Lombok. It may he known as 



Bufo cavator sp. now 



Type: Museum of Comparative Zoology, No. :M70, from Ampenan, 

 Lombok Island. 



Closely related to Bufo biporcatus Tschudi. Crown with bony ridges, 

 rather feebly developed, viz., a supraorbital and a parietal, forming 

 together a straight, or nearly straight, line, and a short orbital tympanic; 

 snout short, with prominent can thus rostralis ; interorbital space slightly 

 broader than uppereyelid; tympanum distinct, circular, about | diameter 

 of eye; first linger as long as second, toes fully webbed except the fourth 

 toe, which extends far beyond the web. Subarticular tubercles simple; 

 two moderate metatarsal tubercles; tarsus without a fold. The hind 

 limb being carried forward along the body, the tar.so-metatar.sal articula- 

 tion reaches to the nostril. Upper surface with scattered warts which are 

 not spiny; paratoids very prominent, small, almost circular. Brownish 

 above, marbled with light yellowish ; fore and hind limbs cross-barred 

 with, yellowish; beneath yellowish, throat dark brown. 



This species may be distinguished from Bufo biporcatus at once by its 

 much smaller tympanum, which is almost circular instead of vertical- 

 oval. In //. biporcatus the upper boundary of the tympanum is formed 

 by the orbito-tympanic ridge, which is not the case with this species. 

 The shape of the tympanum is quite different in the two species; and in 

 this new one the cephalic crests are not prolonged as far posteriorly as 

 they are in biporcatus.
