with a brilliant greenish gloss; the shaped inner margin 

 of the fore wing (which in I. last's is edged with white) blue ; 

 the shining patch near the base on the hind wing black in 

 place of greyish, smaller, and not margined with white; the 

 anal angle black. 



Underside. — Fore wings as in /. iasis. Hind wings with 

 the space, which is contained between the black line over the

 of silvery blue through the centre. In /. iasis the margin 

 only is bordered from the lobe to the end of the black line.

Distinguished by the darker blue and the greenish gloss 

 above and by the large patch of red at the anal angle below.

IV. — Description of a new Species of Crocidura from the 

 Amur Region. By Gr. E. Dobson, M.A., FlR.S. 



The species of Crocidura are generally as characteristic of 

 the tropical and subtropical parts of the Eastern Hemisphere 

 as those of the genus Sorex are of the temperate and subarctic 

 regions. It is therefore interesting to record the discovery of 

 a species of the first-named genus at so high a latitude as 

 that through which the River Ussuri flows. The type of 

 this species, which proves to have been hitherto undescribed, 

 was found by me in the collection of the Zoological Museum 

 of the Imperial Academy of Sciences at St. Petersburg. 



Crocidura lasiura. 



Larger than C. araneus and differing from that species 

 conspicuously in the much longer, denser, and darker coloured 

 fur, which is almost the same on both surfaces, in the hairiness 

 of the tail, which is well covered with short hairs from which 

 long ones project, in the much larger size of the pes and 

 manus, and in the remarkable elevation of the premaxillary 

 bones. Whereas in C. araneus the anterior maxillary tooth 

 exceeds the third incisor in cross section at the base, in this 

 species the third incisor considerably exceeds that tooth in
