Show 32 MR. P. L. SCLATER ON SOME N E W SPECIES [Feb. 5, This species is more constant in cranial characters and in coloration than its two nearest allies. In general appearance it strongly resembles 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. Interorbital 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 bill 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. 2.

[Eeceived December 19, 1888.] The following species of the family Dendrocolaptidae, so far as I can make out, appear to be undescribed. They are based on specimens in the British Museum, and in m y own collection and that of Messrs. Salvin and Godman. 1. UPUCERTHIA BRIDGESI, sp. nov. Above brown, rump more rufous, head more cinereous; lon°-, 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 2*8. Hab. Bolivia (Bridges). Mus. Brit. This species comes nearest to U. montana, having the whole tail rufous, but the wings and tail are shorter, and the body is much whiter beneath. |
