species referred by Dollman ^ to C. sururce Heller, of Lado, but 

 it is quite a different form of the same group, larger and lighter 

 colored. The Nile is apparently a barrier between these two forms 

 and the specimens from Wadelai and Mongalla mentioned by Dollman 

 under siiriircE seem to represent this new species. Dollman mentions 

 a very pale colored example of the C. nyansce group from Unyoro 

 as in some ways intermediate between nyansce and the specimens 

 from east of the Nile which he referred to sururo'. Two similar 

 specimens from Unyoro (Hoima and Butiaba) in our collection 

 indicate the strong probability of direct intergradation between these 

 forms. 



CROCIDURA PARVIPES NISA, subsp. nov. 



Type from Kibabe, Kisumu, British East Africa. U. S. National 

 Museum No. 182440, skin and skull of adult 5 (teeth moderately 

 worn). Collected January 20, 1912, by Edmund Heller. Orig. 

 No. 5126. 



Description. — A small, short-tailed form related to Crocidiira 

 lutrella Heller and to C. parvipes Osgood. Color almost precisely 

 as in the type of parvipes, but upperparts slightly darker ; tail darker, 

 more blackish, above ; and outer side of arms same color as upper- 

 parts of body, not whitish as in parvipes. Skull about same size as in 

 parvipes but with heavier rostrum and wider palate, the unicuspid 

 rows further apart; small upper unicuspid teeth of approximately 

 same size and well overlapped, as in parvipes. 



Measitrements of type. — Head and body, 80; tail vertebrae, 38; 

 hind foot, dry, 11. 3. Skull: condylobasal length, 19.6; maxillary 

 breadth, 6.9; breadth of braincase, 9.0; median depth of braincase, 

 5.3; mandible, ii.o; upper toothrow, entire, 8.9. 



Remarks. — Only a single specimen of this new subspecies is in 

 the collection. The locality from which it came is almost exactly 

 half way between the widely separated regions, Lado Enclave and 

 the Taita Hills district of southeastern British East Africa, which are 

 the type localities of the only obviously closely related forms (lutrella 

 and parvipes). The Field Museum of Natural History has kindly 

 lent me, through Mr. W. H. Osgood, the type specimens of Croci- 

 diira parvipes and other African shrews for study in thig connection. 

 A specimen from Fort Hall, British East Africa, in the National 

 Museum collection, which I refer to parvipes rather than to nisa, is 

 clearlv intermediate between the two.
