New Species of Macroscelides and Glauconycteris. 255 
The northern Reithrodontomys also just enters South 
America, a single species—f&. Séderstrémi—occurring in 
Kcuador. 
The exact position of Phyllotis boliviensis is also some- 
what doubtful, as, in spite of its ungrooved incisors, it shows 
many points of resemblance to Huneomys pictus and sublimis. 
These conclusions have been arrived at in consultation and 
agreement with Dr. J. A. Allen, whose advice has naturally 
been of much assistance to me. 
XXXIV.—New Species of Macroscelides and Glauconycteris. 
By OLDFIELD Tuomas, F.R.S. 
Macroscelides somalicus, sp. n. 
Closely allied to M. Peasei* from Abyssinia, agreeing 
with that species in size and all important characters. But 
the general colour is quite different, being paler and of a 
more fulvous or pinkish-buffy tone, not to be matched in 
Ridgway—something between ochraceous buff and vinaceous 
buff would be the nearest. This colour is only spread over 
the dorsal area, the flanks being abruptly paler and greyer. 
Postauricular patches well-marked fulvous buffy, whiter 
close to the bases of the ears. Other characters as described 
in M. Peasez. 
Dimensions of the type, a fully adult male (measured in 
the flesh) :— 
Head and body 117 millim.; tail 1467; hind foot (s. u.) 
33; ear 24. 
Skull: greatest length 36; basal length 31; greatest 
breadth 20°5; length of nasals 13°5; interorbita] breadth 6:1; 
length of upper tooth-row 18. 
Hab. Arabsiyo, Somaliland. Altitude 4000 feet. 
Type. Adult male. B.M. no. 98. 6. 9. 2. Collected 
December 1, 1897, and presented by R. McD. Hawker, Esq. 
Another younger specimen from the same region collected 
and presented by HE. Lort Phillips, Esq. 
These specimens had been wrongly assigned to WM. Revoiliz, 
Huet, of which the Museum now contains a good series pre- 
sented by Dr. A. E. Atkinson. 
* Ann. & Mag. N. H. (7) viii. p. 154 (1901). 
+ This seems overstated. In its present condition the tail is rather 
more than 130 millim. long.
