412 MR. G, A. BOULEXGEli, ON ORIENTAL [Apr. 28, 



broad as long, usually defined behind by a more or less distinct 

 ti'ansverse fold ; snout truncate or obtusely pointed, projecting 

 beyond lower jaw, as long as or a little shorter than eye ; canthus 

 I'ostralis sharp ; loreal region vertical or a little oblique, concave ; 

 nostril equally distant from eye and from end of snout ; inter- 

 orbital space concave, its width 1-g- to 2 times that of upper 

 eyelid (narrower in the very young) ; tympanum usually feebly 

 distinct, rarely hidden, its diameter I to | that of eye, from 

 which it is separated by a distance equal to the diameter of the 

 latter. Fingers obtuse or feebly swollen at the end, first as long 

 as or a little longer than second, which measures -f to |- length of 

 third ; no subarticular tubercles ; no distinct metacarpal tubercles. 

 Toes rather short, obtuse or feebly swollen at the end, with a mere 

 rudiment of web or, at most, ^ webbed ; no subarticular tubercles ; 

 a flat, very indistinct inner metatarsal tubercle. Tibio-tarsal arti- 

 culation reaching the shoulder, the commissure of the jaws, or the 

 temple ; tibia § to i length from snout to vent ; foot as long as or 

 shorter than tibia. Skin of upper parts smooth or with scattered 

 conical warts, old specimens with bony deposits on the head and 

 anterior part of the back ; a strong glandular fold from eye to 

 shoulder, usually another on each side of the back ; upper eyelid 

 Avith a sharp, raised edge, which is produced into a more or less 

 distinct point or " horn " ; this point may be very indistinct (var. 

 aceras Blgr.), or very miich developed, measuring nearly f diameter 

 of eye; as a rule it does not measure more than ^ diameter of 

 eye ; an indication of a similar appendage on the tip of the snout 

 rarely present * ; a more or less developed pointed tubercle usually 

 present behind the commissure of the jaws ; limbs usually with 

 oblique transverse glandular ridges ; throat smooth, belly with small 

 tubercles. Olive-brown above, uniform or variously marked with 

 darker or lighter ; a more or less distinct large triangular dark 

 spot between the eyes, the base forwards, and a dark oblique bar 

 below the eye ; limbs with more or less distinct dark ci^oss-bars ; 

 lower parts pale brown, spotted or marbled with darker ; a white 

 tubercle on each side of the breast. Male without vocal sac.
