THELODERMA LEPROSA- 237 



slightly concave; iuterorbital space as broad as the upper 

 eyelid; tympanum distinct, small, about one fourth the 

 diameter of the eye ; a parotoid from the eye to the shoulder 

 continuous or divided in two or three parts. Fingers free, 

 the first shorter than the second; disks very small. Toes 

 vsrebbed , the membrane reaching the disks of the first and 

 second toe , the first articulation of the others , but ex- 

 tending with a fringe to their tips; disks of the toes 

 a little larger than those of the fingers. Hind limb very 

 long , being extended forwards along the body , the heel 

 reaches far beyond the snout ; subarticular tubercles distinct ; 

 a narrow tarsal fold. Upper parts covered with warts and 

 tubercles; skin at the ventral side and around the vent 

 granular. 



Colour : (spirit-specimens) above yellowish-brown , varie- 

 gated with dark; large dark-brown spots, light-edged and 

 with a withe centre , along the median line of the back 

 and on the limbs ; a dark band across the head between 

 the frontal edges of the eyes ; beneath colourless. 



Length from snout to vent 42 m.m. 



Two specimens from Java, collected by Boie & Macklot, 

 two from Sumatra by S. Muller. 



The characteristics, by which B. borbonicus differs from 

 B. cruentatus, are: its longer hind limbs, the limb being 

 extended forwards along the body , the snout marks nearly 

 the half of the tibia; its narrower head, the interorbital 

 distance being not broader than the eyelid ; its distinct 

 tympanum ; its colour. Bufo borbonicus agrees with B. lep- 

 topus in its slender hind limbs; but this species is distin- 

 guished by having the first finger as long as the second; 

 by wanting the parotoids etc.

Tschudi in his Classification der Batrachier (Mem. Soc. 

 Scienc. Nat. Neuchatel T. II, 1839, p. 32 and 73) des- 

 cribes under the group of the Hylidae a genus Iheloderma^ 

 based upon a specimen , which he met with in the Ley- 

 Notes from tUe JLieyden Mixseum , Vol. V.
