48 ME. G. A. BOULENGER ON THE EEPTILES 



There are two metatarsal tubercles — an inner, oval, flattened, and an outer, roundish, 

 rather indistinct. There is not a trace of a fold along the inner edge of the tarsus. 



The skin of the head is rough with very small warts, which become large on the 

 hinder half of the upper eyelid and on the occipital region ; on the back and sides and 

 on the upper surface of the limbs the warts are very prominent, round, of larger and 

 smaller size, studded with pores as in Bombinator ; on each side of the back the warts 

 are more elongate and confluent, so as to form an indication of a lateral glandular fold, 

 which is, however, frequently broken up, and does not extend beyond the sacrum. 

 Above the temporal region is a large elongate wart, which might be termed a parotoid 

 gland. The fore limbs are nearly smooth. The lower surfaces are smooth except the 

 belly and the lower surface of the thighs, which are feebly granulate. 



The upper surfaces are of a uniform purplish brown, and the lower uniform yel- 

 lowish.

A single female specimen was collected by Mr. Guppy on Treasury Island. 



This species, one of the stoutest and most toad-like of the genus, has as nearest ally 

 the East-Indian Bana kuhlii. The most important characters which distinguish it 

 from that species are the more posterior vomerine teeth, the larger head, the distinct 

 tympanum, the absence of a tarsal fold, the shorter web, and the shorter limbs.

The vomerine teeth form two short, straight, transverse series inserted on the 

 posterior edge of a large triangular base, the anterior angle of which reaches the inner 

 corner of the large choanse, while the toothed posterior border is behind the level of 

 the choanse ; the space between the two series is wider than the length of one of them. 

 There are no tooth-like processes in the lower jaw. The Eustachian tubes are nearly 

 the same size as the choanee. 



The head is very large and subtriangular ; its length is contained twice and two 

 thirds in the distance from the end of the snout to the vent, and is a little less than 

 its width. The snout is obtusely acuminate, and measures once and one third the 

 diameter of the orbit ; the tip of the snout projects a little, and the profile forms a 

 gentle slope ; the nostril is considerably nearer the tip of the snout than the orbit ; the
