226 ON REPTILES AND FROGS FROM SINGAPORE. [Feb. 1, 



terval between nostril and eye. Eye of moderate size, the diameter 

 about equal to the length of the fourth finger. Tympanum distinct, 

 nearly as large as the eye. Lower jaw with two prominent apophyses 

 in front, fitting into hollows inside the upper jaw ; in a female sent 

 these apoj)hyses are inconspicuous. Vomerine teeth on two straight 

 ridges running obliquely back from the interior angle of the inner 

 nostrils, and converging behind so as to meet, if prolonged, nearly in 

 a right angle, but rather widely separated ; a strong osseous transverse 

 ridge behind the choanae. No vocal sac. A strong fold from behind 

 the eye running horizontally to over the tympanum, then turned down 

 at an obtuse angle and running to the shoulder. Posterior portion 

 of upper eyelid tubercular. Skin of body and limbs smooth. Limbs 

 stout, the tips of both toes and fingers slightly swollen ; the distance 

 from vent to knee is about half the length of the body from snout 

 to vent or a little more ; from vent to metatarsal tubercle is longer than 

 the body. The metatarsal tubercle is elongate, not flattened. The 

 toes are scarcely fully webbed ; the terminal two phalanges of the 

 fourth toe have only a narrow fringe along their sides, and the web 

 is deeply emarginate ; a narrow fold along the inside of the foot. 



Colour (in spirits) light brown above, one specimen (a male) having 

 a pale stripe down the back, very little paler below, the sides and 

 lower portion of the limbs, the sides of the body, breast and chin 

 marbled with rich brown.

Three specimens are sent— two apparently males, the third a 

 female. I believe all were obtained at Singapore ; but I have not 

 heard positively that tliis was the case. 



This form is closely allied to Rana fusca \ but has a much 

 broader head ; the eye is smaller, and the tympanum larger; the 

 muzzle is flatter, the nostrils nearer together, and the web between 

 the toes of the hind feet much less developed. 



In the specimens of R. fusca from Peuang, described by Stoliczka, 

 there does not appear to be any passage towards the Singapore form ; 

 for the toes are said to be fully webbed. Mr. Boulenger informs 

 me that he considers R. fusca also a variety of R. macrodon. 



\n the Journal of the Asiatic Society of Bengal for 1879, vol. 

 xlviii. pt. 2, p. 130, I described a supposed new species of Hyp- 

 sirhina under the name of H. maculata. I overlooked the fact that 

 this name had previously been given by Dumeril and Bibron to the 

 Chinese species H. bennetti. Under these circumstances I propose 

 to change the name of the Burmese form to Hypsirhina maculosa.
