Show 128 DR. .1. C. GRAY ON THB BRADYPODID-E. May 2, by Theobald to T. indica. I am enabled to make this identification because Blyth has given such accurate measurements and descriptions of this specimen that it is impossible to mistake it for any other species. In describing the type he refers to another specimen smaller than it and having the appearance of great age, with most of the plates of its carapace more or less completely united, so that the form of some of them cannot be traced. This is the specimen referred by Theobald to Manouria emys in his catalogue, and is the one bearing the names of the sternal plates in the handwriting of Dr. Falconer. This specimen can hardly be said to be in fragments, as the carapace is entire with the exception of a small portion which has been broken off the anterior margin. The sternum, also, is nearly perfect, as shown in m y drawing, although it wants the dermal plates. The skull and the remainder of the skeleton, however, are absent. It is interesting to observe that all the dermal plates, with the exception of those which Blyth described as being more or less completely united, have disappeared, and that these seem to have remained adherent to the carapace, owing to their being united into a mass which retained a firm hold of it. In connexion with this disappearance of the dermal plates, I would also observe that this specimen geuerally has a decided appearance of having been partially macerated, but not to any great extent. It is evident, from what I have stated regarding the notes in his owu handwriting on this specimen, that it had been in the possession of Dr. Falconer.* The explanation appears to be that Mr. Blyth gave Dr. Falconer the less valuable specimen for his observations. Having seen the disputed skull in London, m y impression is that it is that of T. phayrei, and that Mr. Theobald's account of its history is strictly accurate. The type is a stuffed specimen and in capital condition. Like the other stuffed Tortoises in this museum, however, no wires were employed in mounting it, so that the circumstance that the skull of so-called Scapia falconeri has no wire-holes does not indicate much. 4. Notes on the Species of Bradypodidce iu the British Museum. By Dr. J. E. G R A Y , F.R.S. &c. [Received April 6, 1871.] (Plates XXXV.-XXXVII.) Having received various specimens of this family in the British Museum from Mr. Carmiol, from Costa Rica, as the type of Dr. Peters's new species Cholcepus hoffmanni, and specimens of Arctopithecus from the Cordillera del Chucu, Veragua, in Costa Rica, and from Dr. Seemann from Nicaragua and from other parts of South America, I have been induced to compare them and to send to the Society the following notes as a result of m y observations.
