Thus, if a fresh genus were to be made for these two skulls, the two species would differ greatly in the form of their teeth, though agreeing as to the number. I hesitate, therefore, to separate them, not being able to ascertain if any external distinctions accompany the absence of |^|« Though the skull from Manilla is quite adult and more ridged than that from the College of Surgeons, yet it is much smaller than the latter, its length being only 8"'6 instead of 9"*6. The scent-glands lie beneath the surface of a valve-like antero-posteriorly directed cutaneous inflection, more or less naked, and situated between the penis and the testes in the male, and analogously in the female. Temminck says \ " Le plus grand nombre des paradoxures est muni d'un organe semblable." With the kind assistance of Mr. Bartlett I have verified the existence of this pouch in one of the Paradoxures, named P. typus, living in the Gardens; and I have also noted that the skin around the anus is naked. The pupil is linear. Thus the genus Paradoxurus has the characters before enumerated as those of Viverra, except Nos. 6 (sometimes), 24, 45 (sometimes), and 47. As to character 26, it is possible in some species the anus may open into a saccular depression; but I have not observed it or any record of its so doing. Chatin is silent as to the genus Paradoxurus. I do think it probable that when the species of this genus have been well worked out, it will be found to be subdivisible into two or more genera. As it is, however, I can find no characters to justify the separation of any Paradoxures into the genus Paguma of Gray ; but it is otherwise as regards Arctogale. The genus Arctogale was instituted by Prof. Peters, but not published by him. It was adopted from him, and published by Dr. Gray2. The type species of the genus is described in Temminck's ' Monographies,' vol. ii. p. 333, under the name of Paradoxurus trivirgatus; and he figures (pl. 63) the entire skeleton (| size of nature), with the skull and dentition (of the natural size). It has been described under the same name by Gray in P. Z. S. 1832, p. 68, and by G. S. Midler in Verhand. i. sp. 3, p. 55. Its external form does not appear to have been figured hitherto, and has therefore been given here. There are nine skins and three skulls of this species in the British Museum, one skull (No. 1656 a) being labelled Paguma stigmatica, which is really but a synonym. Arctogale trivirgata comes from Singapore and Burmah, and also from Java and Sumatra according to Temminck (where he savs it inhabits the mountains of from 3000 to 3500 feet elevation), and from Tenasserim according to Blyth. A. stigmatica is said by Temminck (' Esquisses Zoologiques,' p. 121) to have been found in the south of Borneo. The size attained is considerable, the length of the head and body being sometimes 58"*4, and that of the tail 43"*2. 1 L. c. p. 313. 2 P. Z. S. 1864, p. 542; and Catalogue of Carnivora, 11* |
