Show lb/9.J ON MAMMALS AND BIRDS FROM MADAGASCAR. 767 somewhat shortened, wanting the terminal twist. From the examination of other specimens preserved by Mr. Garrod, and now in the Museum of the College of Surgeons, I may add that Canis rutilans, C. primeevus, C. cerdo, C. chama, and C. magellanicus have all folded caeca; but differences can be observed in the length and mode of folding, both in them and in the species stated by Mr. Garrod to resemble C. familiaris, though without a larger series it is impossible to say whether some of these differences may not be due to individual peculiarity. It is, however, clear that the form of the csecum has nothing to do with a geographical division of Canidse ; nor is it, as far as is yet known, correlated with any other structural modification. The female example of the very handsome and rare Red Wolf or Fox (Canis jubatus) from Buenos Ayres, which died lately, after a residence of two years in the Gardens, has enabled m e to give a figure of the smallest (relatively to the size of the animal) and simplest form of csecum yet observed in the group. It lies by the side of the ileum, without the slightest inclination to a curve in either direction. Its length is slightly less than three inches, and its greatest diameter one inch. From a contracted base it expands gradually to the middle, and continues of a cylindrical form to the termination in a conical apex. There was no striking deviation from the ordinary canine type in any of the remaining viscera of this animal which were forwarded for my examination. The lobes and fissures of the liver agreed in all essentials with those of the common Dog. In the tongue the lytta (the absence of which in Lycaon pictus is noted by Garrod) was well developed1. 2. Second List of Mammals and Birds collected by Mr. Thomas "Waters in Madagascar. B y E D W A R D B A R T L E T T, Curator of the M u s e u m and Public Library, Maidstone. [Eeceived November 15, 1879.] (Plate LXIII.) Since my first paper on the Mammals and Birds of Madagascar, I have received several small collections from M r . T. Waters (who still continues his labours, and is now in South-east Betsileo country) ; and it affords m e much pleasure to bring before the Society a list of those species which are not included in m y former list. Among the species I find one new and interesting M a m m a l belonging to the genus Nesomys, and two new species of birds of the following genera, viz. Cypselus and Zapornia, a description of which will be found under the genera which they represent. 1 Since this note was communicated to the Society, Mr. Ockenden, the Prosector's assistant, has shown me the caecum of the type specimen of Canis rudis, Gunther from Demerara, which died in the Gardens in April last. Though not quite «o small proportionally as in C. jubatus, it is also straight. a P. Z. S. 1875, p. 62. |
