Show 1877.] SIR V. BROOKE ON THE DEER OF THE PHILIPPINES. 55 having been sawn through in the manner adopted by taxidermists, leave but little doubt in m y mind as to the correctness of this opinion. Another skull in the Musee d'Anatomie (No. 1559 in Cat.) is, I think, the second skull mentioned by Cuvier. In addition to these skulls, there are in the same museum three skulls collected by Hombron and Jacquinot in Guam. In these five skulls in the Musee d'Anatomie, and in the immature stuffed specimen in the Musee d'Histoire Naturelle at Paris consists as far as I have been able to ascertain, the entire well-authenticated material referable to the deer of the Marianne Islands which is contained at this present moment in European museums. Compared with the skull of the male obtained by Diguet in Luzon (the only authenticated skull of an adult Cervus philippinus which I have as yet discovered), the skulls of the deer of the Marianne Islauds present in my opinion no characters in common in which they differ from the Luzon specimen. Each of the five skulls exhibits remarkable individual peculiarity, the difference between the two most dissimilar being greater than that existing between some of the skulls and that of Diguet's specimen. Similar individual cranial peculiarities are shown in a large series of skulls of Cervus aristotelis collected on the Neilgherry Hills, in Southern India, in my own collection. The great convexity at the junction of the frontals and nasals mentioned by Cuvier and Pucheran, and considered as of specific value by the latter, is shown in great excess by one of the Marianne skulls, less decidedly by another, and scarcely, if at all, by any of the remaining three. The presence or absence of canines is, as has been shown by Pucheran in the case of both the Marianne and the Luzon Deer, dependent more or less on the age of the animal, these teeth being generally lost shortly after the animal attains full maturity. As regards Quoy and Gaimard's immature specimen, it resembles in every important particular a specimen ( $ of list, p. 53) of similar age bred in the Jardin des Plantes from the specimens collected by Diguet in Luzon. . The evidence therefore lies, I think, clearly in favour of the opinion that the deer of the Marianne Islands was originally imported from Luzon; but in the present state of our knowledge respecting this group of deer I think it would be premature to express a decided opinion upon the subject. It is fully possible that it was from some other part of the Philippines that the Mariannes were stocked with deer, and that the Philippines possess, in addition to such comparatively widely distinct species as Cervus philippinus and Cervus alfredi, representative species, for which, notwithstanding their lesser degree of specific distinction, zoologists may find it necessary to retain distinctive titles. The following Table contains the measurements ol a skull and horns preserved m the British Museum (655 b in Cat.). No history is attached to this specimen, which has been for many years in the collection. It bears a striking resemblance to that described by |
