markedly concave above. Nasals comparatively broad be- 

 liind. Palatal foramina unusually short, falling nearly a 

 millimetre short of the level of the front of m}- ; well open, 

 not narrowed behind. 



Incisors slender, narrow, bevelled laterally. Molars as 

 usual, the length of the tooth-row noticeably greater than in 

 Swiss specimens. 



Dimensions of the type (measured in flesh) : — 



Head and body 115 mm.; tail && ; hind foot 21 ; ear 13. 



Skull: greatest length 27; condylo-basilar length 24'3 ; 

 zygomatic breadth 14"5; nasals, lengtli 7"5, breadth behind 2'2; 

 interorbital breadth 4; palatilar length 12; p-datal foramina 

 4'5 ; length of upper molar series (grinding-surface) 5"8. 



Hah. Aspromonte, Calabria, extreme South Italy. Type 

 from S. Enphemia. Altitude 1000 m. 



Type Male. B.M. no. 6. 8. 4. 9. Original number 2575. 

 Collected 18th July, 1906, by A. Robert. 



When Mr. Miller wrote his revision* of the European 

 forms of Evotomys no species of the genus was known from 

 the south of Italy, and the capture of a specimen in the 

 Aspromonte mountains by Mr. Hobert is therefore of much 

 interest. I am, however, informed by Dr. Forsyth Major 

 that Dr. Cavanna obtained an example on Monte Pollino 

 about 1880, so that this is not absolutely the first discovery 

 of the genus in the "great toe" of Italy. 



E. N. hallucalis may be readily distinguished from its 

 Swiss relative by its large size, long tail, long skull, short 

 palatal foramina, narrow incisors, and long molar series. 



XXXIII. — Ttvo new Genera of small Mammals discovered hy 

 Mrs. Holms-Tarn in British East Africa. By Oldfield 

 Thomas. 



The British Museum owes to Mrs. Holms-Tarn a small 

 collection of mammals obtained by her in British East Africa 

 not far from Nyeri. Although only ten species were obtained 

 altogether, it is remarkable that two of them are not only 

 new, but represent new genera, thus showing how much 

 more there is still to be done in this rich region in spite of all 

 that Dr. and Mrs. Hiude have achieved in the same district. 

 The other animals collected were Funisciurus Jacksoni, 

 de Wint., Graphiuriis mnrinus, Desm., Otomys irroratus
