HEDGEHOGS AND SHREWS OF TURKEY — OSBORN 



561 



In Anatolia, C. leucodon was trapped together with C. ruasula along 

 streams under bracken and other dense vegetation and in thick 

 ground litter m hardwood forest. Near Istanbul, C. leucodon, along 

 with C. suaveolens, was trapped in dense grass under poplar trees. 



The characters used by Miller (1912) and EUerman and Morrison- 

 Scott (1951) to separate C. leucodon from C. russula can not always 

 be used with satisfaction. Dental characters are useful only when 

 dealing with young animals and an overlap of measurements of the 

 two species is rather marked (tables 3 and 4). 



Dr. Henry W. Setzer of the Smithsonian Institution was kind 

 enough to check my material; his notes on the differences between the 

 two species based on a comparison with specimens in the British 

 Museum are: 



C. leucodon is markedly whiter on the belly, with the white extending farther 

 up the side. The tail is markedly bicolor in all pelages. There is a pro- 

 nounced dark streak of color over the tarsus and onto the hallux. The skull 

 is generally flat in the braincase; sides of the skull (braincase) nearly parallel. 

 C. russula is pale grayish on the belly, not extending markedly on the sides. 

 Tail not bicolor; no dark colored streak on tarsus or hallux. Skull rather 

 rounded dorsally and sides quite convergent anteriorly. Both leucodon and 

 russula are of about the same body and cranial size as well as in proportion. 



A large series of specimens from Scalita, Trabzon district, in the 

 British Museum were originally said to be C. leucodon by Thomas 

 (1906) but were later referred to C. lasiura (Ellerman and Morrison- 

 Scott, 1951). The tails of these shrews range from 38-45 millimeters
