 interorbital breadth 26*5; palate length (exclusive of median 

 spine) 62*5 ; breadth of posterior palate 16 ; aiitero-posterior 

 diameter of p^ 12'9 ; greatest diameter of m^ 17*5, antero- 

 posterior diameter of its inner lobe 12"1.

Hah. Fort Hall, Kenya District, British East Africa. 



Type. Ohi male, B.M. no. 4. 12. 6. 8. Presented bj 

 Mrs. S. L. ilinde. 



Since the above was written, Mr. F. J. Jackson has pre- 

 sented to the Museum another specimen of this otter, also a 

 male, obtained some years ago on Lake Naivasha. It 

 agrees very closely with Mrs. Hinde's example in colour and 

 size, the basal length of the skull being 116 mm. Tlie nasal 

 opening, however, is narrower and higher, its shape being 

 therefore less constant than might have been expected. 



Funisclurus pijrrhopus leonisj subsp. n. 



Closely allied to the Gold-(3oast F. p. leucostigma^ Temm., 

 but with the following differences : — Middle of crown and 

 top of muzzle dark olivaceous like the back, the rufous or 

 yellowish which surrounds the eyes not extending across the 

 muzzle as it does in leucostig ma. Ears larger^ conspicuously 

 white behind, the white forming also a prominent postauri- 

 cular patch behind their posterior bases ; in leucostigma, 

 although there is some white behind the ears, it is much less 

 conspicuous and less extended. Light lateral band narrower. 

 Flanks a richer rufous than in leucosthjma ; the outer sides of 

 the hips especially rich rufous; in leucostigma the sides of the 

 hips are only a dull suffused fulvous. Middle of underside of 

 tail dull and inconspicuous rufous, instead of bright and 

 prominent fulvous or rufous. 



Dimensions of the type (measured in the flesh) : — 



Head and body 200 mm.; tail 150 ; hind foot (s. u.) 41; 

 ear 12'5. 



JSkuU : greatest length 49; length of upper tooth-series 9*5. 



llab. Bo, Sierra Leone. Altitude 120 m. 



Tijpe. Female. B.M. no. 4. 11. 1. 5. Collected 20th 

 January, 1904, by Mr. Robin Kemp. Two specimens. 



It is to be noticed that while the Hanks and sides of hips 

 are more rufous than in leucostigma^ the muzzle and the under- 

 side of the tail are less so. The white on and behind the ears 

 is also noticeably more conspicuous. 



Arvicanihis setosus, sp. n. 

 A pale-coloured species without dorsal stripes.
