Bufo cavator Barbour, Mem. Mus. Comp. Zool. Harvard Coll., XL1V, N°. I, 

 1912, p. 74, pi. VI, fig. 22. 



Head with a supraorbital, a parietal and a short supratym- 

 panic bony ridge, the two former ones forming together a 

 straight, or nearly straight line; snout short; canthus rostralis 

 prominent; interorbital space slightly broader than the upper 

 eyelid; tympanum distinct, circular, about 3 / 5 the width of the 

 eye. First finger as long as second; toes, except fourth, entirely 

 webbed ; subarticular tubercles single ; two moderate metatarsal 

 tubercles; no tarsal fold; the tarso-metatarsal articulation reaches 

 the nostril. 



Upper parts with scattered warts, which are not spiny ; 

 parotoids very prominent, small, almost circular. 



Brownish above, marbled with light yellowish; beneath yel- 

 lowish, 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 B. 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 poste- 

 riorly as they are in biporcatus." (Barbour). 



Habitat: Lombok.

Habit rather stout. Head broader than long, with a canthal, 

 a postorbital, a narrow supratympanic, a supraorbital and a 

 parietal bony ridge, the two latter ones forming together a 

 straight or nearly straight line; snout not projecting, as long 

 or nearly as long as the upper eyelid, and as long as deep; 

 canthus rostralis angular; loreal region oblique, concave; nostril 

 nearer the tip of the snout than the eye; interorbital space 

 a little broader than the upper eyelid ; tympanum close to
