species, C. dolichura, thereby extending the range of the animal considerably. 
The small foot, only 12.5 mm., will at once separate it from the preceding 
species without recourse to the skull characters. The type is the only known 
specimen. 
Crocidura schweitzeri Peters. Schweitzer’s White-toothed Shrew 
Crocidura schweitzert Peters, Monatsb. Akad. Wiss., Berlin, 1877, p. 187: Liberia. 
A medium-sized shrew, dull brown above, slaty gray below; total length 138 mm., tail 49, 
foot 14.5, ear 9; mammae three pairs, inguinal. 
This is perhaps the commonest of the Crociduras in Liberia. It was origi- 
nally described from a specimen sent from Liberia by the Austrian collector, 
Schweitzer. An adult female was secured by Biittikofer in a grassy field at 
Cape Mount, and others from Schieffelinsville and Hill Town were described as 
C. stampflit by Jentink under the belief that they were a different species. 
Dollman (Ann. Mag. Nat. Hist., vol. 15, p. 526, 1915) has shown, however, 
that this name is but a synonym of C. schweitzerit. Miller has recorded it from 
Mount Coffee and we secured two others in the interior at Gbanga. Its range 
extends into Sierra Leone. 
Crocidura biittikoferi Jentink. Buttikofer’s White-toothed Shrew 
Crocidura biittikoferi Jentink, Notes Leyden Mus., vol. 10, p. 47, 1888: Robertsport, Liberia. 
Distinguished externally from the preceding species by its much shorter tail; total length 
116 mm., tail 40, foot 15. 
This shrew seems still to be known.only from the type specimen, and may 
be told at once by its short tail. 
Crocidura nigricans Bocage 
Crocidura nigricans Bocage, Jorn. Se. Lisboa, vol. 1, p. 29, 1889: Quindumbo, Angola. 
Distinctly paler in tint than C. schweitzeri, the belly contrastingly gray; tail with abundant 
bristle hairs, foot small; total length 130 mm., tail 53, foot 12.5, ear 8. 
A Crocidura obtained on the Du River, at our first camp, differs in its small 
foot, as well as in color and proportions from the other shrews known previously 
from Liberia and seems to correspond very closely with C. nigricans of Angola 
or perhaps with C. boydi of the Uele River. In the lack of authentic specimens 
of either for comparison, however, we have regarded it as representing the former, 
and give the measurements above. The second upper unicuspid is broader 
than the third. 
Crocidura occidentalis cara Dollman. Large White-toothed Shrew 
Crocidura occidentalis cara Dollman, Ann. Mag. Nat. Hist., ser. 8, vol. 15, p. 525, 1915: Jala, 
Sierra Leone. 
Size large, total length 197 mm., tail 78, foot 19; grayish brown above, paler below; tail 
with many scattered bristle hairs. 
An adult male of this large shrew was captured near Monrovia under some 
loose stones by the side of a cleared space, July 21, and is in process of moult
