42 Miller — Five New Shrercs from Europe. 



smaller than in fh'ocidura russula, but otherwise they show no peculiari- 

 ties. 



Measurements. — External measurements of type: total length. 100: 

 head and body. 68: tail, 32; hind foot, 13 (12). Measurements of an 

 adult female from the type locality: total length. 110; head and body, 

 75; tail, 3o; hind foot, 13 (12). 



Cranial measurements of type: greatest length (exclusive of incisors), 

 17.6 (19);* greatest postorbital breadth, 8.8 (9.6); greatest antorbital 

 breadth, 6.2 (6.8 : mandible, 9 (10); entire maxillary toothrow, 8.-1 (9): 

 entire mandibular toothrow, 8 (8.6). 



Specimens examined. — Two, both from the type locality. 



Remarks. — Croeidura sieula differs from C. rnssvla in the characters 

 that would be expected from the known peculiarities of other members 

 of the Sicilian favma. 



Croeidura caudata sp. nov. 



Type.— \o\mix adult female (in alcohol) No. 103,302 United States 

 National Museum. Collected at Palermo Sicily, June 21, 1900, by Dane 

 Coolidge. Original number, 1365. 



Characters. — Somewhat larger than Croeidura sieula (total length about 

 115, hind foot about 15) and ditl'ering from this as well as from other 

 European species in the size and great length of the tail, which when 

 laid forward over back reaches to middle of ear. 



T^^n'^.^The tail forms about 42 per cent of the total length and at mid- 

 dle is 3 mm. in diameter. Near base it is distinctly four-sided, but be- 

 yond middle becomes sub-cylindric. The tip is flattened laterally for 

 about 13 mm. evidently as the result of an accident. Scales arranged 

 in indistinct rings, of which there are about 7 to the millimeter at mid- 

 dle. The rings are partlj- obscured by fine short hairs; and the longer 

 bristles with which the tail is sprinkled are more abundant than in. 

 Croeidura russula and C. .ncula. 



Colo?-. — Color after six months immersion in alcohol essentially as in 

 Croeidura sieula but fur both above and below with a dull slaty cast, and 

 transition from drab of back to gray of underparts less abrupt. 



Skull and teeth. — The skull is so injured that the details of its form 

 cannot be seen, but apparently the rostrum is relatively shorter and the 

 interorbital region broader than in either Croeidura russula or ('. xievla. 

 Teeth as in the related species except that the first upper unicuspid is 

 larger and the second and third are so crowded that the third is tightly 

 wedged into the concavity on the inner side of the large premolar. It 

 is thus partly hidden by the small anterior cusp of the larue tooth, 

 while in the related species it is so far removed from the latter that a 

 distinct break in the toothrow is usually seen when skull is viewed from 

 the outer side. How far these characters may be constant cannot be

 russnla from Waremme. Belgium.
