434 BATRACHIA. 



Var. y. Greyish-olive above variegated with brown ; a white line from the snout to the 

 vent ; hind limbs with undulated brownish lines, and with a few brown cross bars ; lower 

 parts uniform whitish. 



Var. S. Bluish-green, all the upper parts densely variegated with black ; a white line along 

 the canthus rostralis, superciliary, and supratympanic fold. Lower parts whitish, spotted 

 with black. 



This species has been found in Ceylon only, and does not appear to be uncommon. The 

 largest specimen I have seen is 1^ inch long, the length of its hind limb being 2^ inches. 



IXALUS TEMPORAUS. (Plate XXVI. fig. E.) 



Snout of moderate length, longer than the eye, pointed, wth angular canthus rostralis. 

 The foremost part of the snout is on the same level with the nostril. Tympanum small, not 

 quite half as large as the eye. Upper parts perfectly smooth. Disks of the fingers and toes 

 well developed. The length of the body equals the distance between vent and heel ; tarsus 

 without cutaneous fold ; metatarsus with a small tubercle ; interdigital web short, not 

 extending to the outer phalanx of the third and fifth toes ; fingers quite free. Upper parts 

 brownish- or greyish-olive ; a dark cross band between the eyes, becoming lighter dorsad ; a 

 dark-brown band from the eye, over the tympanum, bent downwards to the humeral joint ; 

 loreal region generally brownish. Femur and lower leg with three brownish cross bars each, 

 only the middle of which is distinct. Whitish below, throat dotted with brown. 



I have examined six examples of this species, all alike in form and coloration ; the largest 

 are 15 lines long, the hind limb being 21 lines ; they have the male and female sexual organs 

 fully developed. Ceylon. 



IXALUS FEMORALIS. (Plate XXVI. fig. D.) 



Snout short, rather shorter than the eye, obtusely rounded in front, without canthus 

 rostralis. Tympanum very small, covered by the skin. Skin on the back finely granular. 

 The length of the body equals the distance between vent and heel ; a narrow fold of the skin 

 along the outer edge of the tarsus and fifth toe ; metatarsus with a small indistinct tubercle ; 

 interdigital web short, not extending to the outer phalanx of the third and fifth toes ; fingers 

 quite free ; disks of the fingers and toes well developed. Upper parts uniform greenish, the 

 lower whitish ; margin of the upper jaw, tarsus, and fore-arm white. The anteiior and 

 posterior sides of the femur are perfectly colourless, and only a nairow stripe along its upper 

 side is green. 



I have seen only one specimen of this species ; it is from Ceylon, and 1 3 lines long, the 

 length of the hind limb being 21 lines.
