Report on the Malacostraca, Pycnogonida and some Entomostraca. 581 



Nymphon groenlandiciiin lias only been taken 64°54' N., 55'10'W., 

 395 fm., 3.8° G. ("Ingolf"). 



Chœtonymphon tenelliim is included here, though its position is 

 not quite certain. In the Norwegian North-Atlantic Exped. Sars 

 records 2 specimens from W. of Finmarken 7Г 25' N., 15°41' E., 

 1134 m., — 1.0° C. and states, "as this station lies in the cold area, 

 the species must unquestionably be regarded as a true arctic form." 

 The "Ingolf" localities are opposed to this however: W. of the Fæ- 

 roes 61°42' N.. 9°36'W., 545 fm., 4.8° C; S. of Iceland 63°13' N., 15° 

 41' W., 600 fm., 4.5° C, and W. Greenland 65° 14' N., 55°42' W., 420 fm., 

 3.-)° C. This is the only material as 3'et, but it thus seems to be a boreal 

 deep-water form, which however can also live in negative temperatures. 



Paranymphon spinosuin has been taken 63°30' N., 54°25' W., 582 

 fm., 3.:3° С and 64°56' N., 36°19' W., 204 fm., 4,1° С (Meinert "Ingolf") 

 and Golfe de Gascogne 650 — 1710 m. (Caullery: Ann. Univ. Lyon 1896). 



Colossendeis colossea bas been found E. of Greenland 64°34' N., 

 31°12' W., 1300 fm., + 1-6°C. and 61 44' N., 30 29' W., 1135 fm., 

 -f- 3.0° C. (Meinert "Ingolf"); further, eastern N.America between 

 38°45' N. and 41°33' N. and from 65 47' W. to 73=1072^ W., 523— 

 1186 fm. (Wilson "Blake"). 



Colossendeis macerrima has been taken : E. Greenland 64°34' N., 

 31°12'W., 1300 fath., + 1.6° C. (Meinert, "Ingolf") at N.America 38°18' N., 

 1685 m. (Wilson), Brede Bugt (W. Iceland) 76 fath. (Meinert, 1. с.) 

 and (?) Golfe de Gascogne, 1710 m. (Caullery, Ann. Univ. Lyon 1896, 

 p. 362). 



3. Littoral fauna. 



This fauna can be subdivided into an arctic and a boreoarctic 

 group. A number of the species are found at Finmarken, but no 

 further south on the coast of Norway; when the main distribution 

 is arctic, however, the species are considered here as arctic, even 

 though Finmarken is boreal. 



The arctic littoral fauna may be divided into the following 

 subgroups: ЗА endemic, W-est Greenland species (there are no en- 

 demic East Greenland species); 3B endemic, Greenland species; 3C 

 species which range from West Greenland to Spitzbergen or further 

 east, but are not found N. of Siberia; 3D species which range from 

 West Greenland over Spitzbergen to and including Siberia and are 

 thus probably circumpolar. 



The boreoarctic littoral fauna embraces the species which in 

 Europe have their southern boundary south of Finmarken; a number 

 range to France, a few to the Azores. This fauna may be divided into 

 two groups 3E. and 3F, corresponding to 3C and 3D.
