276 RANIDiE. 



As may be seen from the preceding table of measure- 

 ments, this form readies to a very large size, much 

 exceeding that of the two others. 



Forma typica. 



Inner metatarsal tubercle strong, compressed, pro- 

 minent, its length 2 to 3 times in the length of the 

 inner toe measured from the tubercle, and 7 to 10 

 times in the length of the tibia ; when the limbs are 

 folded at right angles to the body, the heels meet or 

 remain narrowly separated ; tibia shorter than the 

 foot measured from the outer metatarsal tubercle. 

 The tibio-tarsal articulation reaches the eye or be- 

 tween the eye and the tip of the snout. Skin smooth 

 or with small warts ; glandular lateral fold very 

 prominent, as broad as or narrower than the upper 

 eyelid. 



Bright green, brown, or blue above, uniform or 

 spotted with black ; hinder side of thighs handsomely 

 marbled with black, and usually with more or less of 

 bright yellow pigment ; vocal sacs white or feebly 

 pigmented. Iris golden, with or without black vermi- 

 culations. 



Males are often of a uniform green colour, without 

 any markings ; females are usually more or less 

 spotted with black, the spots sometimes confluent 

 into longitudinal bands. A light, pale blue, pale 

 green, or yellowish-green vertebral stripe is often 

 present, and the glandular lateral folds are usually of 

 a beautiful gold-colour. A blackish temporal spot is 

 sometimes present. Black cross-bars are usually 

 present on the hind limbs in the females, more often 

 absent or ill-defined in the males. 



Sky- or turquoise-blue specimens are rare, and 

 must be regarded as individual abnormalities due to 

 the absence of the yellow pigment, same as occur also 

 in Hi/la avborea, a fine blue specimen of which (var. 

 meridionalis) was exhibited last summer at the Zoo- 

 logical Gardens, London. Vulpian (C. R. Soc. Biol.
