32 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. eruciger 
is found in the wet valleys of the hill district around Kandy, but he 
has not seen it from any other locality. &. maculatus has a peculiar 
fondness for houses; but &. cruciger, though found amongst plantain- 
groves, &c., seems never to enter houses. 
2. On some new Species and Genera of Birds of the Family 
Dendrocolaptide. By P. L. Scrarer, M.A., Ph.D., 
F.R.S., Secretary to the Society. 
[Received December 19, 1888.] 
The following species of the family Dendrocolaptidee, 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 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.
