LVI. — New Insectivores and Voles collected hy 

 Mr. A. Robert near Trebizond. By Oldfield Thomas. 



During the last quarter of 1905 Mr. Alphonse Robert, 

 already so well known for his South-American collections, 

 made a trip to 'rrebizond, in order to obtain series of the 

 small mnminal-^ of that region, hitherto almost unrepresented 

 in the Briti-h ^iuseum. 



Along the northern coast of this part of Asia Minor there 

 is a strip of forest, some 50 miles wide, sloping northwards 

 to the Black Sea from an altitude of 1500 to 2000 metres at 

 its southern edge. The forest then abruj»tly disappears and 

 an open stej)pe country commences, inhabiti^d by Ilamsters 

 and Spermopliiles, and continuous with the more desert 

 countries further south. 



Compared with this more open and desert country the 

 coast-forest has a very different fauna, of a distinctly northern 

 character. Moles and black-toothed shrews reach their most 

 southern recorded limit here, while the occurrence of an 

 Evotomrjs is the most striking piece of evidence in the same 

 direction. 



Mr. Robert's work was done at two localities in the heart 

 of the forest-strip — Sumela, about 30 miles south of Trebizond, 

 where he stayed at the monastery of the same name, and 

 collected from about 1000 to 1300 metres altitude ; and 

 Scalita (or Metosh de Sumela), a village in the same valley 

 as Sumela but about 3000 m. lower. 



Collecting in this region proved to be a work of very great 

 difficulty, owing both to the character of the people and to the 

 distance from Trebizond, whence all provisions had to be 

 brought. In spite of these drawbacks, however, Mr. Robert 

 has i-ent home a beautifully ])repared collection of over 300 

 specimens, belonging to about 24 species. 



In working these out I have received great assistance from
