Show 38 MR. J. L. BONHOTE O N [Jan. 14, 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 up into blotches. There likewise remains the possibility that our specimen has been rather increased in size by the art of the taxidermist. Considering, however, tha,t so many local forms of Equus burchelli 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. Vienna, Nov. 20th, 1901. 4. On a further Collection of Mammals made by Mr. Th. H. Lyle in Siam. By J. L E W I S BONHOTE, M.A. [Received November 19, 1901.] The following paper gives an account of a further small consignment of Mammals sent home by Mr. Th. H. Lyle from Siam. Although 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 fktvigida form a valuable addition to the National Collection, and help considerably to the more correct understanding of their respective groups. 1.

Chiengmai, 28th Feb., 1901. These two individuals closely agree with the description in my paper quoted above, with the exception that the hind-quarters could hardly be styled "very dark brown"; this apparent discrepancy is, however, merely due to faded pelage, for of the two specimens one is lighter than the other. I append the measurements taken in the flesh, as they are |
