14 MR. O. THOMAS ON MAMMALS FROM [Jan. 17, 



represented in Abyssinia by a second species described in the accom- 

 panying footnote \ Dr. Emin's specimen agrees in every respect 

 with typical West-African individuals, and shows no approach to 

 the new Eastern form. 



36. Georychus ochraceo-cinereus, Heugl. 

 a,h. S. Beilima, Monbuttu, 14/7/83. 



The type specimen of this rare species was obtained by its describer 

 in Bongo, only a few degrees north of the present locality, and is 

 now in the Stuttgart Museum, where, by the kindness of Dr. Krauss, 

 I have had an opportunity of examining it. In the collection worked 

 out by Dr. Leche tliere were also several Georychi, divided by him 

 into two species — a larger darker-coloured one, determined as 

 G. damarensis, Og., and a smaller sandy one, considered to be 

 G. ochraceo-cinereus. The first of these was so named on my 

 authority, Dr. Leche having sent me one of the specimens to compare 

 with Ogilby's type. At that time, however, not having at all inves- 

 tigated the subject, I did not know that there were two species 

 found in this Central district, and assumed that the specimen sent 

 was G. damarensis, to which I still think it is exceedingly closely 

 allied. Now, however, Dr. Leche's descriptions and excellent 

 figures show the distinction of the two forms, of which the names 

 given by him must certainly be reversed, G. ochraceo-cinereus being 

 the larger, and G. damarensis the smaller form, as I have been able 

 clearly to make out by measurements taken on the two typical 

 skulls as compared with those given by Dr. Leche. I can therefore 

 only express my sincere regret to Dr. Leche at having led him 

 wrong, and must plead the close relationship of the two forms as my 



1 LOPHUROMYS FLAVO-PUNCTATUS, Sp. n. 



Size and proportions as in L. sikapusi, but differing markedly from that 

 species in the character and colour of its fur, which, instead of being long, 

 sleek, unicolor, and all of one sort, is short, comparatively coarse, and finely 

 freckled all over with orange or yellow, and has a considerable number of 

 longer hairs intermingled with it. The individual hairs are brown for the 

 greater part of their length, broadly tipped with orange or yellow, the former 

 colour along the top of the head and back, the latter on the flanks. Belly dull 

 yellowish white, not sharply defined. Hairs round the Iront of the base of ear 

 prominently tipped with bright orange, those behind it pale yellow. Feet 

 irregularly patched with white and dark chocolate-brown. Tail closely covered 

 with short crisp hairs, brown above, white beneath. 



Skull much as in L. sikcqnisi, but the zygomata more widely expanded 

 anteriorly, and the interorbital region narrower and flatter above. The inter- 

 parietal also is shorter antero-posteriorly, and the nasals are narrower and 

 more pointed behind. 



Dimensions of the type, an adult specimen in skin : — Head and body 129 

 millim. ; tail 51 ; hind foot 21 ; ear 10. 



Skull — basal length 26 millim. ; greatest breadth 16 ; nasals, length 12-6, 

 greatest breadth 3 ; interorbital, breadth 56 ; interparietal, length o, breadth 

 9-8 ; palatal foramen 66 ; length of molar series 5. 



Hab. Shoa(C'«7J<. W. C.Harris). 



Two specimens of this species were received from the East-India Company's 

 Museum in 1860, and were no doubt collected by Capt. Harris during his 

 mission to Shoa in 1843.
