A. R. MOLANDER, TWO NEW SPECIES OF DEOAPODS. 5 



In other morphological respects this species resembles 

 the other members of the genus. 



There are only two specimens, which were taken in lit- 

 toral region of Behring Sea, Behring Island, Vega exp. ^Vs 1879. 



The largest specimen of these has the following dimen- 

 sions. 



Total length of the specimen 40 mm, 



length of the carapace 14 mm. 



length of the right cheliped 27 mm. 



length of the carpus of the right cheliped . 9 mm. 



length of the hand of the right cheliped . . 13 mm. 



breadth of the carpus of the right cheliped 11 mm. 



breadth of the hand of the right cheliped . 9 mm. 



length of the carpus of the left cheliped . . 6 mm. 



length of the hand of the left cheliped . . 6,5 mm. 



breadth of the carpus of the left cheliped . 3,5 mm. 



breadth of the hand of the left cheliped . . 4,5 mm. 



Other Eupagurids in Behring Sea. 



Eupagurus Bernhardus (Linné). 



Habitat. 

 Behring Island, littoral region 1 sp. Vega exp. ^^"^Vs 1879. 



Brandt consider the North-Pacific form of the Ewpa- 

 gurus Bernhardus as a special variety [granulato-denticulata) 

 and Benedict as a species (Alaskensis). The specimen, which 

 I ha ve investigated, shows in all cases complete conformity 

 to those of the European Seas. I can not admit, that the 

 hands of its chelipeds are especially tuberous and any other 

 characters, which can be used as distinctions between diffe- 

 rent species, I liave not been able to discover. 



The Ewpagurus Bernhardus is to be found in three different 

 regions, the West Atlantic, the East Atlantic and the North 

 Pacific. All these regions are well separated and any trans- 

 migration between them is now impossible. The depth of 

 the Atlantic Ocean separates the inhabitants of its west and 

 its east coasts, the arctic water those of the European Seas 

 from those in the Behring Sea. Ortman assumes that a
