MR. P. L. SCLATER ON SOME NEW SPECIES [Feb. 5, 



This species is more constant in cranial characters and in coloration 

 than its two nearest allies. In general appearance it strongly re- 

 sembles the likewise Ceylonese R. eques. 



A slender bony parieto-squamosal arch. Skin adherent to the 

 rugose nasals and fronto-parietals ; latter bones broadest in front, 

 without or with a mere indication of postorbital processes. Inter- 

 orbital space once to once and a half the width of the upper eyelid. 



Digital expansions larger than those in R. maculatus, that of the 

 third finger measuring one half to two thirds the diameter of the 

 eye. The tibio-tarsal articulation reaches the end of the snout or 

 a little beyond. 



No large dorsal spots, but usually a large dark or black-edged 

 hourglass-shaped marking extending from between the eyes to in 

 front of the sacrum ; hinder side of thighs brownish, uniform or with 

 small whitish spots. 



Hab. Ceylon. Nevill states that he has examined some hundred 

 or more, of both sexes, of this frog and of R. maculatus, as found in 

 Ceylon, without coming across any intermediate forms. R. cruciger 

 is found in the wet valleys of the hill district around Kandv, but he 

 has not seen it from any other locality. R. maculatus has a peculiar 

 fondness for houses; but R. cruciger, though found amongst plantain- 

 groves, &c., seems never to enter houses.

 Dendrocolaptidce. By P. L. Sclater^ M.A., Ph.D., 

 F.R.S., Secretary to the Society. 



[Eeeeived December 19, 1888.] 



The following species of the family Dendrocolaptidse, so far as I 

 can make out, appear to be undescribed. They are based on specimens 

 in the British Museum, and in my own collection and that of Messrs. 

 Salvin and Godman. 



1. UpUCERTHIA BRIDGESI, Sp. nOV. 



Above brown, rump more rufous, head more cinereous ; long, 

 narrow superciliaries white ; wings blackish, inner primaries and 

 secondaries rufous at the base and edged externally with rufous ; 

 tail uniform rufous: beneath dirty white, flanks flammulated with 

 brown ; under wing-coverts whitish ; inner margins of wing-feathers 

 pale rufous : bill black ; lower mandible at the base yellowish ; feet 

 blackish. Whole length 7"0 inches, wing 3"1, tail 28. 



Hab. Bolivia {Bridges). 



Mus. Brit. 



This species comes nearest to U. montana, having the whole tail 

 rufous, but the wings and tail are siiorter, and the body is much 

 whiter Ijcneath.
