RANIDJ3. 839 



like depressions, — a cliaracter which is also observed in examples of the species 

 from Ningpo. 



The Yunnan specimens more closely resemble the frogs from Borneo, which 

 were described by Giinther as R. compicillata, but which he now allows to be one of 

 the many varieties of this widely distributed species. 



In the British Museum, there is a frog from Ningpo distinctly referable to this 

 species, and which is characterised .by the same fine transverse, almost concentric and 

 wavy, glandular ridges which have been observed in Ceylon examples of the species. 

 It is a circumstance worthy of note that this specimen shows no trace of vomerine 

 teeth, and yet the body alone measures 2*10 inches, and has strongly developed 

 apophyses on the lower jaw. 



Rana yunnanensis, n. s., Plate LXXVIII. 



Head broader than long ; the snout rounded and somewhat pointed ; nostril 

 nearer the snout than the eye ; canthus rostralis feeble ; tympanum visible, but in- 

 distinct, half the size of the eye ; a glandular fold from the eye over the tympanum 

 to the shoulder ; vomerine teeth but little developed and in two short oblique ridges, 

 on the inner side of the choanse, convergent behind, but separated from each other 

 by a wide interval. Openings of the internal nostrils small, round, those of the eus- 

 tachian tubes very small. Tongue frea, cordate, deeply notched. A feeble fold along 

 the metatarsus and along the first toe enclosing a small but strong laterally compressed 

 sharp-edged crescentic tu.bercle. A fold along the fifth toe. Eingers tapering, tips not 

 enlarged ; the first, second, and fourth subequal in size, the third slightly longer than 

 the second, a few minute horry spines on the upper surface of the thumb. Toes 

 incompletely webbed, the membrane emarginate, reaching to the extremities of all 

 the toes but the fourth : fourth toe, one-third longer than the third. Upper surface 

 densely covered with round warty tubercles, cash surmounted by a small black horny 

 granule. Smooth beneath. Uniform greenish olive-brown, with obscure dark bands 

 from the orbit to the lip and on the upper surface of the limbs ; under surface 

 brownish-yellow, reticulately spotted with deep brown. Erom the vent to the meta- 

 tarsal tubercle is rather more than the length of the body. Length of body 2"-08 : 

 vent to metatarsal tubercle 2"*16. The two specimens were procured at Hotha, 5,000 

 feet above the sea.

Prom the obscure nature of the vomerine teeth in this species, and its general 

 resemblance to Bicroglossus aclolfi, I was at first disposed to refer it to the genus 

 Dicroglossus, but the unquestionable presence of vomerine teeth proved it to he alcana. 

 The types of Dicroglossus adolfi possess posteriorly convergent eminences from the 

 inner margins of the choange, which feel rugose when a fine instrument is drawn
