1879.] ON MAMMALS AND BIRDS FROM MADAGASCAR. 767 



somewhat shortened, wanting the terminal twist. From the exami- 

 nation of other specimens preserved by Mr. Garrod, and now in the 

 Museum of the College of Surgeons, I may add that Canis rutilans, 

 C. primcevus, 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 impos- 

 sible to say whether some of these differences may not be due to indi- 

 vidual peculiarity. 



It is, however, clear that the form of the caecum has nothing to 

 do with a geographical division of Canidae ; 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 me to give a 

 figure of the smallest (relatively to the size of the animal) and simplest 

 form of caecum 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 developed 1 . 



2. Second List of Mammals and Birds collected by Mr. 

 Thomas Waters in Madagascar. By Edward Bartlett, 

 Curator of the Museum and Public Library, Maidstone. 

 [Received November 15, 1879.] 

 (Plate LXIII.) 



Since my first paper on the Mammals and Birds of Madagascar, I 

 have received several small collections from Mr. T. Waters (who still 

 continues his labours, and is now in South-east Betsileo country) ; 

 and it affords me much pleasure to bring before the Society a list 

 of those species which are not included in my former list. 



Among the species I find one new and interesting Mammal be- 

 longing 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 Pro- 

 sector's assistant, has shown me the caecum of the type specimen of Canis rudis, 

 Giinther, from Demerara, which died in the Gardens in April last. Though not 

 quite so small proportionally as in C. jubatus, it is also straight.
