ANNOTATED LIST OF SPECIES. 



SOREX ARANEUS BOREALIS Kastschenko. 



1905. Sorex araneus horealis Kastschenko, Oda. MjieKonnT. 3an. CHdnpn m 

 TypKecTaHa [Synopsis mammals western Siberia and Turkestan], I, Chiroptera 

 and Insectivora, p. 85. Tomsk. 



Six specimens from alpine meadows at 9,000 to 9,500 feet in 

 Tchegan-Burgazi Pass, and tliree specimens from the forests near 

 Tapucha at 6,400 feet. The series, collected in July and August, 

 contains specimens in both the summer and winter pelages. This 

 race averages somewhat smaller than any European form of' araneus, 

 except the Spanish granarius. It is otherwise very like true araneus. 

 No definite type-localit}^ is given in the original description, but the 

 account is largely based on specimens collected by Middendorff in 

 the "far north." The range, as given b}^ Kastschenko, includes all 

 of extreme northern Siberia, all the mountain ranges from the Altai 

 eastward, and possibly all of eastern Siberia. 



Measurements of Sorex araneus horealis from the Altai Mountains, Siberia. 



SOREX ROBORATUS Hollister. 



1913. Sorex rohoratus Hollister, 

 March 13. 



Smiths. Misc. Coll., vol. 60, No. 24, p. 2, 



The unique type-specimen of this shrew was trapped in the heavy 

 forests of Pinus cemhra about 5 miles south of Tapucha, August 7. 

 The species is readily distinguishable in the flesh from Sorex araneus
