NO. 15 NEW INSECTIVORA FROM. AFRICA — IlFXI^ER 5 



This species has the general appearance of hindei, but is much 

 smaller, with the dorsal and neutral colors sharply marked and con- 

 trasted. 



CROCIDURA PLANICEPS, new species 



Flat-headed Shrew 



Type from Rhino Camp, Lado Enclave ; adult male ; number 

 164641, U. S. Nat. Mus. ; collected by J. Alden Loring, January 23, 

 1910; original number, 8837. 



Characters. — Skull very different in shape from other Crocidura, 

 the brain-case very flat, with a marked depression at its anterior 

 termination in the interorbital region, the profile of the rostrum 

 ascending slightly anterior to this depression ; general body size of 

 hildegardcB. 



Coloration. — Above uniform seal brown, this color carried well 

 down on sides, where it merges gradually into the lighter smoky gray 

 of the under parts. Tail seal brown like the upper parts. Feet 

 somewhat lighter brown than the back. Lateral glands distinctly 

 marked by an oblong patch of whitish hair. Hair very short, only 

 2.5 mm. on rump, and uniform in color to the roots on upper parts. 

 Hair of under surfaces, however, showing a narrow basal band of 

 plumbeous. 



Measurements. — Head and body, 71 mm.; tail, 53; hind foot, 12.3. 

 Skull: condylo-incisive length, 18.3; breadth of brain-case, 8; length 

 of upper tooth-row, 8; condylo-incisive length of mandible, 11. 



This species in bodily size resembles hildegardcc, but it has de- 

 cidedly smaller feet and skull, and darker coloration. From the bi- 

 color group, of which ciininghamei is a form, it differs markedly in 

 shape of skull, dark feet, and greater size. In skull characters it is 

 quite distinct from any described species. The skull has somewhat 

 the posterior elongation and narrowness of Heliosorex, but it is 

 much less developed and not at all intermediate between this genus 

 and Crocidura. 



There are four other adult specimens from the type locality in the 

 collection, and another from Hoima which possesses the skull char- 

 acters of the species, but is somewhat smaller. 



CROCIDURA LITTORALIS, new species 



Butiaba Naked-tailed Shrew 



Type from Butiaba, east shore of Albert Nyanza, Uganda; adult 

 male ; number 164642 ; U. S. Nat. Mus. ; collected by J. Alden Lor- 

 ing. January 6, 1910; original number, 8598.
