Report on the Malacostraca, Pycnogonida and some Entomostraca. 61 1 



from the Indian Ocean and Gnathophausia and E. sculpticauda further 

 from the Pacific. E. unguiculata is also found in the Western Medi- 

 terranean. 



Hansenomysis Fyllae was known earlier (H. J. Hansen "Ingolf" 

 1908) only from Davis Strait and S.W. of the Færoes; but in 1911 

 Tattersall gives 6 localities for the species at S. W. Ireland, depth of 

 bottom 550—900 fm., depth of net 0—700 fm., temp. 8.35"— 16.20° C, 

 35.35—35.53 *'/oo salinity. 



The 4 species last-mentioned seem to be West-Atlantic, as they 

 have never been found at Norway. 



Boreomysis tridens is known from W. Greenland^ N. Norway and 

 W, Ireland. 



Boreomysis arctica is exclusively boreal, in spite of its specific 

 name. It ranges from W. Greenland (not known from E. Greenland) 

 and eastern N.America to Norway; southwards it goes to Capri. 



Boreomysis microps seems to be very common at W. Greenland 

 ("Tjalfe"), where, curiously enough, the "Ingolf" has not found it; 

 further, it is Western Atlantic: it is known from Nova Scotia to the 

 Færoes and W. Ireland, as also from the Azores. 



Longithorax fuscus, a new species from the "Ingolf" Exped., is 

 mentioned by H. J. Hansen ("Ingolf") only from 2 localities, namely 

 49°27'N., 13°33'W., 2800 m. wire out, 2600 m., and6I°30'N., 17°08'W., 

 1800 m., wire out. Later it has been taken at 2 other localities, 

 namely 50°59' N., ir52'W., 900— 1064 fm., 15.4° C. (Tattersall 1911) 

 and 60°07' N., 48°26' W., 2000 m., wire out ("Tjalfe"). 



Erythrops erythrophthalma ranges from W. Greenland and Cape 

 Cod to Spitzbergen, Kara Sea and the whole coast of Norway ; further, 

 it has possibly been taken in the Mediterranean. 



Meterythrops picta is known from E. Greenland to the Hebrides 

 and W. Ireland. 



Amblyops abbreviata ranges from Davis Strait to Norway and 

 W. Ireland. 



Pseudomma roseum is distributed from W. Greenland to Nova 

 Zembla and Norway; it is found perhaps also at eastern N.America. 

 The record of its occurrence at E. Greenland (Ohlin 1901) is probably 

 due to confusion with P. frigidum (see H. J. Hansen "Ingolf" 1908, 

 p. 110). 



Pseudomma parvum was only known earlier from Lille Karajak- 

 fjord in W. Greenland (ca. 71° N., Vanhoffen) but is noted by Tatter- 

 sall 1911 from S. W. Ireland, 50°48'N., 11°41'W., 900 fm. These 2 

 occurrences are very interesting in zoogeographical regards, as the 

 one belongs to the deep part of the Atlantic, the other to the deep 

 basin N. of the ridge in the Davis Strait; but, as also already
