Show 1889.] MAMMALS OF KINA BALU. 229 2. CYNOPTERUS ECAUDATUS, Temm. a. 3000 feet. 29/3/88. Previously only known from Sumatra. This species may be readily distinguished from the somewhat similar C. lucasi, Dobs. \ by its rather smaller size, by not possessing any trace of a tail, and by the attachment of its wing-membrane to the distal third of the first phalanx of the hallux instead of to its base. 3. TUPAIA FERRUGINEA, Raffl. a-b. 3000 feet. 3/87. c. 8000 feet. 5/2/88. 4. HYLOMYS SUILLUS DORSALIS, Thos. Ann. Mae*. N. H. (6) ii. p. 407(1888). a. 6 • 8000 feet. 2/88. * Type of var. b. 6*. 8000 feet. 9/2/88. c _ 3000 feet. 21/3/88. Essential characters as in the typical variety, but with a more or less distinct black line running from between the eyes down the neck to the middle of the back. Dimensions:-Head and body (c.) 116 millim.: tail 16; hind foot 25. Since all the five or six specimens of Hylomys obtained on Kina Balu show a black dorsal line, sometimes, it is true, faint and indistinct, but always present, I believe this to be a valid geographical race, characteristic at least of Mount Kina Balu, if not of the whole of Borneo, whence, up to the present, no other specimens have been obtained. It should be stated, however, that Dr. F. A. Jentink, of the Leyden Museum, where the type of H. suillus is preserved, believes it to be not worthy of separation from that animal; but as he is inclined to give, in certain other allied groups, rather less importance to the presence or absence of a dorsal streak than appears to me correct, I do not as yet feel disposed definitely to withdraw the merely varietal name already given to the Kina Balu Hylomys. The true Hylomys suillushas been recorded from Burma, the Malay Peninsula, Sumatra, and Java. 5. CHIMARROGALE HIMALAYICA, Gray. a. Ad. sk. The occurrence of this fine Water-Shrew on Mount Kina Balu is a most interesting fact, and affords a remarkable instance of the relation that the fauna of the mountainous regions of the Malay islands bears to that of the Himalayas. The species has previously only been recorded from Sikhim, Assam, and the Katchin Hills in the North of Burma. The Bornean specimen is rather smaller than the type, its hind foot measuring only 20 millim. in length as against 22*5, but is otherwise identical; this difference in size is very probably only sexual. 1 Ann.
