may be merely individual, for we find among skins of Zebras from 

 the same locality some with pure black stripes and others with 

 brownish stripes. Besides, the transverse stripes on the body of 

 our Quagga show a tendency to bipartition, and the oblique 

 stripes incline to break vxp into blotches. There likewise remains 

 the possibility that our specimen has been rather increased in 

 size by the art of the taxidermist. Considering, however, that so 

 many local forms of Eqims hurchelU have been distinguished 

 during the last few years, it is by no means impossible that the 

 Vienna specimen might be ultimately separated subspecifically 

 from other Quaggas.

4. On a further Collection of Mammals made by Mr. Th. H. 

 Lyle in Siam. By J. Lewis Bonhote, M.A. 



[Received November 19, 1901.] 



The following paper gives an account of a further small consign- 

 ment of Mammals sent home by Mr. Th. H. Lyle from Siam. 

 Althovigh small in point of numbers it contains several specimens 

 of considerable interest, and foremost among these is a fine 

 example of the Siamese Hare, which proves to belong to a 

 species not hitherto described. A specimen of Sciurus atro- 

 dorsalis, in immature pelage, and two specimens of Mustela 

 jlavigula form a valuable addition to the National Collection, and 

 help considerably to the more correct understanding of their 

 respective grovips.

These two individuals closely agTee with the description in my 

 paper quoted above, with the exception that the hind-quarters 

 could hardly be styled "very dax-k brown"; this apparent dis- 

 crepancy is, however, merely due to faded pelage, for of the two 

 specimens one is lighter than the other.
