III. NOTES ON SOME SOUTH INDIAN B A T R A C H I A . By C. R. Narayan Rao, Central College, Bangalore. I. The Larvae of Microhyla rubra and Rana breviceps. These tadpoles have been described by Mr. H. S. Ferguson^ F.Iv.S., late Director of the Trevandrum Museum, in his paper on "A List of Travancore Batrachians," published in the Journal of the Bombay Natural History Society (Vol. XV, p. 499). I am of opinion that Mr. Ferguson has mixed up the larvae of M. rubra with those of the allied species M. ornata, and there is considerable difference between his account of the tadpoles of R. breviceps and the specimens I have collected. These facts sufficiently justify the publication of the following notes, in which I purpose to des-cribe the specimens in full and at the end indicate the chief points wherein I differ. I might add here that examples of all these larvae have been sent to Dr. N. Annandale whom I have to thank for examining them. Larva of M, rubra. H. S. Ferguson, J.B.N. H.S., Vol. XV, 1904, p.506; Boulen-ger, Fauna, p. 491. Towards the middle of Jul}^ a few specimens of this tadpole were obtained at Bangalore from a pond in which rain water had collected. Other tadpoles found in their company were those of M. ornata, R. breviceps and Rhacophonis maculattis. The tadpoles were allowed to complete their metamorphosis in the college aquarium. They may be described as follows : — The head and body. — Head depressed and almost flat, snout broadly rounded but not squarish. Both dorsal and ventral sur-faces of trunk flat. In horizontal section, the body is nearly elliptical. Skin smooth. Eye and nostril. — Nostrils nearer to the snout than the eyes, and are dorsal. The inter-orbital space nearly six times the inter-nasal. Eyes lateral, visible from below and by no means promi-nent. Pupil round. (It is vertical in the adult). Mouth.— Nexy small, nearly terminal or dorsal: broadly triangular or nearly oval. Upper lip better developed, with a horny edge. Beaks, horny teeth and papillae absent. Sensory glands and pits.— A conspicuous white glandular area, somewhat dome-shaped, just behind the mouth or between the nostrils. A number of sensory pits round the mouth, especially
