Report on the Malacostraca, Pycnogonida and some Entomostraca. 613 



Euthemisto compressa and E. bispinosa are placed together by some 

 authors, e. g. H. J. Hansen (V. Grønland 1887, p. 59), whilst others, 

 e. g. G. O. Sars ("Account") and Vosseler (Plankton-Exped.) take them 

 for separate species; when the specimens are not very small (< 1cm.) 

 they are not difficult to distinguish. Both species seem to be very 

 common along the whole of the w^est coast of Greenland, especially 

 in the Davis Strait. E. compressa is known from Greenland, Jan Mayen 

 and W. Finmarken (Sars "Account"), S. W. Ireland (Tattersall 1906) 

 and the Florida Current, Sargasso Sea and southern Equatorial Cur- 

 rent (Vosseler, Plankton-Exped.). E. bispinosa has almost the same 

 distribution, but is not recorded by Vosseler (1. c.) from the southern 

 Equatorial Current. 



Cyphocaris anonyx has tlie most interesting distribution among 

 the plankton Amphipods. It is known from the localities mentioned 

 below, and seems to prefer cold water: "there can be little doubt 

 that this is a cold-water form" (Fow^ler, Transact. Linn. Soc. 1904, 

 ser. 2, vol. 10, part 2, p. 47). Its occurrences are the following: 8 loca- 

 lities in the Davis Strait from 60°07' N. to 64°35' N., 500 m. wire — 

 2000 m. wire ("Tjalfe"); 30 miles S. E. of Cape Farvel, 300 fm. (H.J. 

 Hansen 1887); off Finmarken 69°41' N., 15^51' E., 1591m., bottom- 

 temp. — 1.2° С (Sars, "Norweg. North-Atlantic Exped."); 11 stations 

 at S. W. Ireland (Tattersall 1906); 52°N., 15°W., 510, 1300 and 1500 fm. 

 (Walker, Oceana 1903); 47°38'N., 22°13'40" W., 710 fm., 42° (F?) 

 (Chevreux, "Hirondelle" 1900), Bay of Biscay, 300— 400 fm. (Stebbing, 

 Transact. Linn. Soc, 1904); 46°15'N., 7°09'V^., 0— 3000 m., depth 

 4000 m.; 29°16'N., 16°11'W., 0— 3000 m., depth 3670 m., at the island 

 Hierro (Canaries) 0—3000 m., depth 3817 m. 36°17' N., 28°53' W., 

 0— 3000 m., depth 3410 m.; 36°46' N., 26°41'W., 0— 3250 m., depth 

 3620m.; 37°20'N., 21°40'W., 0—2000 m., depth 3800m. (Richard, Bull. 

 Mus. Océanogr., Monaco, No. 41, 1905); 41° N.,16° V^. (H.J.Hansen, 

 V.Grønland 1887). It is also known from the Pacific: 38°07' S., 

 94°04'W., 1500 fm., 35.3° (F.?) and 32°44' S., 13°5'V\^., 1425 fm., 37° (F.?) 

 (Stebbing, "Challenger" 1888, p. 656 ; C. micronyx = C. anonyx, teste 

 Stebbing, "Tierreich"). 



Metacyphocaris Helgœ has been taken at 3 stations in the southern 

 Davis Strait ("Tjalfe") and at 5 stations at S. W. Ireland (Tattersall, 

 1906, p. 29). 



Earytenes gryllus seems to occur over the whole Atlantic (see 

 below). There can be no doubt, that this species should be referred 

 to the plankton. Sars ("Account", vol.1, p. 87) writes: "all the spe- 

 cimens preserved in our (Christiania) Museum have been extracted 

 from the stomach of large sharks (Scymnus borealisy. H. J. Hansen 

 (V. Grønland 1887, p. 67) records it from stomachs of fishes and
