length of the anterior limbs ; and the hind toes are long, with interdigital 

 membranes well developed. It is as obvious than the present species is a 

 ? Tree-frog,' as that the other is not so : and the proportions of M. guttu- 

 lata would indicate it to be a crawler, rather than a leader ; whereas 

 M. (?) gigas is as obviously a powerful leaper, and as aquatic in its habits 

 as our common 'Golden Frog' (Bana tigrina). The two specimens of 

 M. GUTTTJLA.TA presented by Capt. Berdmore were, he remarks, " beauti- 

 ful creatures of their kind ; the colours being bright : the eyes are bright 

 red with a light blue circle round them." These fine colours have dis- 

 appeared in spirit, but it is easy to perceive that they had been vivid. At 

 present, the back appears of a plumbeous olive-green, with numerous 

 large round spots more or less confluent, of a light dusky colour, the 

 appearance of which may be compared to that of drops of water on an 

 oily surface, tending to unite and flow together : limbs banded with the 

 same colours : the skin of the lower-parts is granulose throughout, and 

 appears to have been orange, marbled and variegated with dusky ; one of 

 the specimens having the throat entirely of the latter hue. The tips of 

 the toes are scarcely dilated. Inhabits Pegu. 



Poltpedates lividus, nobis, n, s. As compared with the common 

 P. leucomystax, this species attains to triple the size, and has the legs 

 and toes proportionally much longer, and the hind-toes are completely 

 webbed (as in P. maemoratus, nobis, p. 188 ante). Length, from snout 

 to vent, 3f in. ; of extended anterior limb 2\ in. ; and of posterior limb 6| 

 in. General form more gracile, and the muzzle less obtuse, than in P. 

 leucomystax. Skin smooth, and slightly granulose only on the hind 

 surface of the thighs. Colour uniform dusky-plumbeous above, probably 

 dull olive-green when alive ; below whitish ; and the membranes of the 

 hind-toes dusky. A specimen one-fourth the size accords minutely in all 

 other respects : but a number of what Mr. Theobald considers to be the 

 young differ in having the tympanic membrane proportionally much larger, 

 and also much nearer the eye ; the general hue being paler, and the upper 

 lip more conspicuously white than in the grown animal. We are satisfied 

 that Mr. Theobald is correct in assigning them to the same species. In- 

 habits the Tenasserim valley, 



Lymnodytes nigrovittatus, nobis, n. s. In this genus it is not always 

 easy to discriminate between species and varieties ; but two very distinct 

 races were obtained by Mr. Theobald, one of which accords with speci- 

 mens from Arakan and from Dacca, and also with Dr. Cantor's descrip- 

 tion of L. ERYTHRiEUs (J. A. S. XVI, 1262). The other, named as above, 

 has distinctly a more obtuse muzzle, and much smaller hind-feet j the
