Arctictis binturong, Cercoleptes'caudivol-vulus, Felis lynx, Lutra vulgaris, Viverra malaccensis.-PRIMATES. Ateles melanochir, A. sp., Brachyteles sp., Cebus sp., Chiromys, Cyno-cephalus babuin, G. maimon, Homo, Lagothrix sp., Lemur macaco, Macacus cynomolgus, M. silenus, Mycetes auratus, Semnopithecus maurus, S. schistaceus. I find that one extreme term in the series of modifications to which the Mammalian coracoid is susceptible is reached in the Edentata (Tamandua, fig. If and Tatusia fig. \ g, p. 589), viz. the con: plete exclusion of the scapula from the fully-formed glenoid facet, by tbe fusion and joint extension of the metacoracoid and scapular epiphyses (Go" and ep., figs. 1 /, g, h). I have only observed this peculiarity in Ateles marginatus and Lutra vulgaris among the higher forms which I have examined. Its independent assumption in them appears, by analogy, to lend additional support to the belief that the overgrowth of the epicoracoid and scapula to enclose the so-called coraco-scapular foramen (fo., figs. 1 d, e, h) is a secondary and independently acquired character. 8. On some new Species of the Land-Molluscan Genus Alycaus from the Khasi and Naga Hill Country, Assam, Munipur, and the Ruby Mine District, Upper Burmah; and on one Species from the Nicobars. By Lt.-Col. H. H. G O D W I N - A U S T E N , F.R.S., F.Z.S., &c. [Received June 20, 1893.] The present paper is to a great extent a continuation of one I read before the Society last year* describing the Biplommatince from the Assam Hill Ranges which Mr. Doherty's excellent collecting had accumulated. The Alyccei now described include those which Mr. Doherty obtained in North Burmah, one species which I discovered myself in Munipur, and another of which examples have lately been sent to me by Colonel Beddome, who received them from Mr. Muspratt, au officer now stationed in the Naga Hill Country. I also take this opportunity to describe a new species of the same genus of which an example, found by Mr. Busby at the Nicobars, was in Dr. Hungerford's fine collection. In 1871 (J. A. S. B. 1871, pi. iv. fig. 3) I figured an Alyceeus from the Naga Hills as "A. ingrami, var." A comparison of it with typical specimens of A. ingrami now shows me that it is quite distinct, and 1 therefore name it A. distinctus. I referred to the same species again in 1874 (J. A. S. B. 1874, p. 150) and gave the many localities where I had subsequently obtained it. I have lately received from Col. Beddome, also from the Naga Hills, 1 See P. Z. S. 1892, p. 509. |
