Arctic Ocean (fragments, U.S.N.M., 36190). 



North Atlantic Ocean [A. H. Clark, 1912] (2, Berl. M., 3082;. 



Erroneous locality. Dr. T. Gislen gives the following record for this species: 

 "South of the Faro-Iceland ridge: A.H.Clark, 1923, 1317 M., +2.4C.;"but there is no 

 such record in the Inqolj report, the memoir to which reference is made. In his syn- 

 onymy he includes a citation to the Ingolf report, giving page 6 as the page upon which 

 this species is considered, whereas the account of the species is found on p. 8. 



These discrepancies arose through the fact that Dr. Th. Mortensen sent to Dr. 

 Gislen the unconnected proofs of the Ingol/ report in which Ingolf station 46, west of the 

 Faroe Islands (lat. 6132' N., long. 1136' W.), 1317 meters, temperature +2.4 C., 

 was inadvertently included in the list of localities from which this species had been 

 obtained. This station was struck out in the proof, and before the final printing the 

 pagination was changed so that Poliometra prolixa appears on page 8 instead of on page 

 6 as given by GislSn. 



Geographical range. Arctic regions; westward to Grinnell Land, southward to the 

 vicinity of Goclthaab, west Greenland (lat. 6324' N.), Kangerdlugsuak, east Greenland 

 (lat. 68 N.), the vicinity of Jan Mayen, the cold deeps west, north, and east of Iceland, 

 the Faroe Channel, and Finmark, and eastward to the Kara Sea and just east of Wilczek 

 Land. 



Bathymetrical range. From 20 to 1960 meters. 



Thermal range. From 1.97 C. to +2.00 C. (a record for 2.10 C. is doubtful) 

 (Schorygin, 1928, gives the range as up to +3 C.); less than a quarter of the 

 are above C.
