CiiHii.h'iin Arctic Expedition, 1918-1S 



where it was taken l>y this expedition as far oast as Bernard harbour, Northwest 



Territory 



in say. the lai'iiT AYo/////\/\> .U//x/x rui/i ( Murdoch) 1 was not 

 i. -lined, though considerable collecting was undertaken near point Barrow, 

 the type locality. Other than those mentioned above there are only two 

 >chi/opod.- which have been reported from near the region covered by the 

 expedition, but not taken by it: Gnathophdusia <//</"* \\illemoes-Suhni 2 and 

 Thysdnoessa spinifera Holme> :; . both from the southern Bering sea, off the coast 

 of Alaska, latitudes r>3 56' 50" X. and f)7 10' X.. respectively. 



The former is a species ranging as far south as the Hawaiian islands in the 

 Pacitic and the A/ores in the At lant ic. but in the Atlantic not known to occur 

 north of the .~>0th parallel': the latter i- strictly a Pacific form, which ranges 

 -outhward along the \\'est American coast nearly to the southern end of Cali- 

 fornia." 



( )f course the commoner arctic forms, such as .!//>/////< Y/////.V/.V mi.rln i Lillej- 

 borg)-' 1 and Thii*<ni<n'xx<i m i/l/i'/n 1 ' and loinjicn mliilu i Kr^yer) 7 are to be expected 

 in this region, as well a- almost any of the thirty-odd species occurring in the 

 Atlantic Arctic or subarctic ocean, a list too long to introduce here. Reference 

 is suggested to: Zimmer, Fauna Arctica, III (Die arktischen Schizopoden), 

 191)1. and Xordisches Plankton. VI (Schixopoden ), 1909. in which all these 

 Species are illustrated and fully keyed out: and Han-en Danish Ingolf Expe- 

 dition, III (Crustacea Malacostraca [), P.nis. and Proc. U.S. Nat. Mus., 

 48 (The Crustacea Kuphausiacea of the I'.S. Xat. Mus. I. 191"). 



In the following list of the species, and the stations at which they were taken 

 reference has been made, in the case of the Mysids, to a plate and description 

 of I he species, and in the case of the Euphausids, to the latest review of the 

 group. The drawings were made from balsam mounts by means of the Edinger 

 drawing apparatus. All of the species, except one of .l///x'x oculata, so indicated, 

 were collected by Mr. Frits .Johaiisen, naturalist of the expedition.
