■Skull: total length, 35 ; zygomatic breadth, 22; interorbital con- 

 striction, 10.6; length of nasals, 11.8; length of mandible, 27; 

 breadth of mandible, 12. 



The immaturity of the specimen which I have made to represent 

 this newly-described race of albiventris can in nowise account for its 

 color characters as contrasted with the typical form, whose habitat 

 Dobson places as " northern tropical Africa." In aj^pearance, as 

 well as in habitat, this race may be said to show some approach to 

 the South African E. diadematus Fitz., but closer examination 

 shows its affinities to be with the northern animal. 



The single skin and skull brought back by Dr. Smith indicate an 

 individual closely approaching maturity, the posterior molar and 

 the canine just cutting through the gums. 



67. Macroscelides rufescens Peters. Rufescent Jumping Shrew. 



This shrew, whose cranial characters so closely ally it to M. in- 

 tufi Smith, is represented by an adult female and an immature male 

 (Nos. 3,829, 3,830), taken respectively at Ehrer and Lanimo on the 

 12th and 16th of August, 1894. The adult is somewhat blacker and 

 less ruddy than Peters' specimens, but the measurements and color 

 pattern are identical. Both specimens are skins with skulls, full 

 data and measurements. 



68. Macroscelides sp. ? 



A* half grown individual (No. 3,828), labeled Waleuso, October 

 26, 1894, is so dark and has such a short tail compared with body 

 that it is probably distinct. Its skull, however, shows near relation- 

 ship to rufescens. It is preserved in alcohol. 



69. Crocidura doriana Dobson. Shoa Shrew. 



An alcoholic specimen of an adult shrew (No. 3,826) in the col- 

 lection was taken at Sheikh Mahomet, October 28, 1894. The skull 

 and dentition are identical with Dobson's Shoa species as figured in 

 the Monograph. 



70. Crocidura sp. ? 



A rather young example (No. 3,827), in alcohol, from Lake Ru- 

 dolf, the skull of which, unfortunately, was lost after being ex- 

 tracted for examination, is of interest. The skin and sparse hairs 

 of tail and feet are white. Tail about half the length of head and 

 body. Color of body dark bluish-gray, lighter beneath. Total 

 length about 100 mm., hind-foot, 12.5. Ears conspicuous. The 

 small size of this specimen makes it improbable that it is C. leucura
