Eleven years ago Mr. Boulenger 1 pointed out the identity of Rana ehrenbergi, Peters ', with tbe common Indian species, Rana cyanophlyctis. I have compared Colonel Yerbury's specimens with some excellently preserved examples of Rana cyanopfdyctis 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 in the British Museum, but Colonel Yerbury 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 paper3 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 1 Cat. Batr. Grad. 1884, p. 110. 3 Monat. Berl.
