328 BATRACHIAN COLLECTION IN THE BRITISH MUSEUM. [Apr. 15, 



two oval, blunt metatarsal tubercles, inner more elongate and nearer 

 its fellow than the tarsal tubercle. The tibio-tarsal articulation 

 reaches the centre of the eye. Skin smooth ; a large, flat, oval lumbar 

 gland. Grey-brown above, with a blackish lateral band ; lumbar 

 gland with a black, light-edged ocellus ; hind limbs with dark cross- 

 bands ; hinder side of thighs white-dotted ; lower parts white, 

 speckled with brown. 



From snout to vent 33 millim. 



A single female specimen from Venezuela, from Dr. Fischer's 

 collection. 



BuFO JERBOA. (Plate XXV. fig. 3.) 



Allied to Bufo leptopus, Gthr., but with still longer hind limbs. 

 The i'emoro-tibial articulation reaches the shoulder, the tibio-tarsal 

 far beyond the tip of the snout, and the tibia measures two thirds 

 the length of head and body. In B. leptojms the tibia measures 

 half the length of head and body, and the tibio-tarsal articulation 

 reaches the eye or between the eye and tip of the snout. Snout 

 strongly projecting; loreal region vertical; interorbital space as 

 broad as the upper eyelid ; tympanum close to, and measuring half 

 the diameter of the eye. First and second fingers equal ; toes one- 

 third webbed. Upper parts with small smooth warts ; no distinct 

 parotoids. Brown above, limbs with darker cross-bands ; an X-shaped 

 dark marking on the middle of the back; throat brown. Male with 

 an internal subgular vocal sac and brown nuptial asperities on the 

 inner finger. 



From snout to vent 30 millim. 



A single male specimen, collected by Ilr. Grabowsky in S.E. Borneo, 

 and mentioned in the list published by Fischer (Arch. f. Nat. 1885, 

 p. 43) as B. leptopus. It is particularly curious to find in Borneo, 

 which is the home of the most long-legged Rana {R. jerboa, Gthr.), 

 a kind of Toad which by far exceeds all others in the length of the 

 hind limbs.
