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. /ucasi, 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, Rafil. 
a-b, 3000 feet. 3/87. 
ec. 8000 feet. 5/2/88. 
4. Hytomys suittus porsauis, Thos. Ann. Mag. N. H. (6) 
ii. p. 407 (1888). 
3. 8000 feet. 2/88. Type of var. 
3. 8000 feet. 9/2/88. 
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 in- 
distinct, 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 im- 
portance 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 im size is very 
probably only sexual.
