CRUSTACEA MALACOSTRACA. 63 



of the Bering Sea in depths of 5 to 159 fm. (Mary Rathbun). The greatest depth at which the 

 species seems to have been taken in Europe is 119 fm. in Skagestrand Bay in Iceland; south of the 

 Alaskan peninsula it was taken in 159 fm.

In Malac. Groenl. I have given a large number of localities for this species, the most northerly 

 at 81 44' N. L. in Grinnell Land (Miers), also along Greenland itself from ca. 78 r / 3 N. L. to 6o43'N. L.; 

 it was taken in 2 3 fm., often in 10 to 20 fm., common in 40 to 100 fm., and was several times found 

 in 118 to 260 fm. Later discoveries in these regions have not appreciably extended our knowledge; 

 it is said by Ohlin and Ortmann that the species is common between 76 and 79 N. L. in 5 to 40 fm. 

 Ohlin gives it also from the west side of Baffin Bay and Pfeffer had his H. amaso from the west side 

 of the Davis Straits. --At East Greenland the species is common atTasiusak, ca. 65 37' N. L. (Kruuse, 

 Ryder Exp. and Amdrup Exp.) ; on the tract from ca. 6972 N. L. to 74"/2 N. L. it has been taken half 

 a score of times (by the 2 ml Amdrup Exp.), in 30 fm., 10 fm., 20 fm., 50 fm., 94 fm., no fm. and 

 120 fm.; in Hekla Harbour at 70 27' N. L., 26 12' W. L. it was taken in i to n fm. (Ryder); and it is 

 noted by Ohlin and Buchholz from numerous localities between 71 35' N. L. and 74 52' N. L., in depths 

 from 2 fm. and down to 186 fm.; lastly it has been taken even a little further north at Shannon Isl. 



1 In the list of synonyms to this species I have not included 5 1 . incerta Buchholz which was founded on a single 

 specimen from East Greenland (Zweite Deutsche Nordpolarfahrt, B. II, p. 272). The reason is that though I consider it to have 

 been founded on a specimen of 5. polaris (Buchholz states however that an epipodite only occurs on the first and second pars 

 of thoracic legs), I am not certain of my interpretation and as I did not wish to omit mentioning a species noted from 

 East Greenland I have preferred to mention it here in a footnote.
