Show 58 MR. NELSON ANNANDALE ON [Feb. 7, individual alveoli and cell-masses are separated from one another by a delicate packing of connective tissue. The Kidney.--(Owen, I.e. p. 44, pi. xiv. fig. 3.) Except at the hylus the kidney is not lobulated. Thickenings of the capsule along certain anastomosing lines give it, however, superficially a lobulated appearance. In the entire absence of any pyramids projecting into the pelvis there is more resemblance to the Tapir than to the Horse. The Bladder and Urethra.- (Owen, I. c. p. 49, pi. xvi.) The seminal vesicles and prostate are more complex than one would be led to suppose from Owen's description and figure. When fully dissected out, the seminal vesicles can be resolved into a number of convoluted tubes, that converge towards the neck of the bladder and unite to form a pair of common ducts which open into the vasa deferentia shortly before their entry into the urethra. This condition is similar to that described by Forbes * in the Sumatran Rhinoceros, but is very different to the arrangement seen in the Sondaic Rhinoceros by Beddard and Treves t, where the seminal vesicles and prostate are quite simple and compact, more nearly resembling the same organs in the Tapir. The prostate is larger and more branched than represented by Owen. There was a well-marked uterus masculinus, not noted by Owen. The following papers were read :- 1. On Abnormal Ranid Larvae from North-Eastern India. By N e l s o n A n n a n p a l e , 13.A . , Deputy Superintendent of the Indian Museum, Calcutta J. [Received December 13,1901.] (Plate VI. §) The two specimens on which the following notes are based were found in a bottle of miscellaneous specimens in the Indian Museum, which had been purchased in 1893 and were said to have come from Northern Cacliar, in Assam. Unfortunately no information can be obtained as to the environment in which the tadpoles (which are not in a good state of preservation) were found. They were the only Batrachians in the bottle, but the Museum also possesses a number of specimens from Tenasserim of what I take to be the normal form of the same larva.
