Eleven years ago Mr. Bouleuger ^ pointed out the identity of 

 Rana ehrenhergi, Peters ', with the common Indian species, Rana 

 eyanophlyctis. I have compared Colonel Terbury's specimens with 

 some excellently preserved examples of Rana ci/at'iojihli/ctis collected 

 quite recently by Lieut. Stanley Flower at Benares, and presented 

 by him to the British Museum, and I am fully convinced of the 

 correctness of Mr. Boulenger's identification. 



The Aden specimens are slightly larger than any examples of 

 the species preserved iu the British Museum, but Colonel Terbury 

 informs me that his largest specimens were specially selected on 

 account of their size. 



As the tadpole of this species has never been described, I take 

 this opportunity to do so, as I am fortunately in the possession of 

 a number of well-preserved specimens obtained by my collector at 

 Hadramaut. I have followed the method of description adopted 

 by Mr. Boulenger in his paper ^ on the tadpoles of European 

 frogs and toads. 



The length of the body is about three fifths the length of the 

 tail, and its breadth three fifths of its length. The distance 

 between the nostrils is about one half their distance from the 

 extremity of the snout, and they are placed nearer to the eyes than 

 to the snout, their distance from the eye about equalling the 

 interorbital breadth. The eyes are on the upper surface of the 

 head, and their anterior border is distant from the snout the length 

 of the interval between their lower border and the spiraculum. 

 The distance between them is slightly less than that between the 

 nostrils and the snout and is about twice as broad as the mouth. 

 The anterior border of the spiraculum is about equally distant 

 from the snout and from the insertion of the limbs, and the 

 opening is directed backwards and upwards, and is more visible 

 from below than from above. The anus is directed to the right. 

 The tail is about three times as long as it is deep and ends in an 

 obtusely pointed tip. The upper caudal crest is very deep and 

 convex, and twice as deep as the lower crest. It is prolonged on 

 to the back to the vertical of the spiraculum, and at its anterior 

 extremity a fold passes to each eye. The body portion of the 

 crest generally lies recumbent in the dorsal furrow. The depth of 

 the muscular portion of the base of the tail is about one half the 

 greatest length of the organ. 



The beak is entirely black and is strongly hooked, the upper 

 portion broadly overlapping the much hooked lower segment. A 

 single marginal upper line of teeth, and two lower lines of teeth, 

 the most internal of the latter being slightly larger than the
