60 MR. E. J. MIERS ON GREENLAND CRUSTACEA. 



The occurrence in fine condition of adult specimens of both 

 sexes of the Branchinecta arctica of Verrill, affords me the op- 

 portunity of correcting an error in the figure of that species 

 in my Eeport on the Crustacea collected by the naturalists of 

 the late Arctic Expedition ; and in an Appendix to the pre- 

 sent paper I have added descriptions of two additional species 

 collected in that expedition and not included in the Eeport. 



The geographical range of species is given, except where I had 

 previously noted it in my Eeport on the Arctic Crustacea ; and 

 some additional localities are cited from Prof. Smith's recently 

 published " Eeport on the Crustaceans of the Atlantic Coast of 

 N. America."

 Several specimens are in the collection from North Greenland ; 

 no definite particulars are recorded with respect to their habitat. 

 This is a very widely distributed species, as it is known to occur 

 on both the eastern and western coasts of the 1ST. Atlantic, and its 

 circum polar distribution extends eastward to the Sea of Okhotsk, 

 where a variety of this species has been found which has been de- 

 signated " alutacea " by Brandt.
