COPEPODA 6l 



North), ill the Polar Sea as far north as 72^30 Lat. North (6^41 Long. West), along the east coast of 

 Greenland as far north as c. 70° Lat. N. In Denmark Strait, in the Atlantic (west of the Faeroes) 

 and in the fjords of Iceland as well as on the west coast of Greenland it has been taken by several 

 collectors. 



In the following I am going to give an acconnt of the number of stations at which the diffe- 

 rent stages and partly the types of the species were taken at the different seasons. 



West Greenland. In Davis Strait, on the west coast of Greenland, the Ingolf Expedition 

 1895, has taken mature females of Ps. uiajor^ at four stations from '/? — "/? ^895, Ps. gracilis at five 

 stations from ^'^/e—^^/y, and Ps. clongatus from a single stat. ^V?- O^ the copepodites (St. V) specimens 

 of Ps. major have been taken at 2 stat. (^^/e — 7?)) of Ps. gracilis at 3 st. (77—^7?) ^""^ ^^ ^^- elongatiis 

 at 2 stat. (7; — "/?); of the copepodites (St. IV) Ps. major was taken at 3 stat. [^^je — 77)1 of Ps. gracilis 

 at 2 stat. (6/7—277) and Ps. clongatus at 2 stat. (7?— "A)- At a single station (7^ St. 29, 65°i7 Lat. 

 North 55^42 Long. West) a single mature male was found, but at no station copepod. of younger 

 stages than the fourth were taken. In contrast to the Ingolf Expedition, by which most specimens 

 were taken in the open sea in vertical hauls in a depth of from 200—0 fathoms, Bergendal and 

 Lund beck have in 1890 taken a good many specimens at the surface and near the coast. On that 

 account, perhaps, almost all the specimens are most naturally referred to the Ps. clongatus type. From 

 "Jakobshavn" 2 mature males |from the same sample 50 f?; 5 y^ (V); 4 y$ (V); 3 yc? (IV); i y (III)] 

 were taken ■^'^/g, mature females were taken at 3 stations (^'/g — ^^l%\ young specimens (V) at same 3 

 stations and Cop. (Ill — IV) at a single stat. (^s/s) only. From Egedesminde 2 mature males were taken 

 ^3/7 [from same stat. 6 f?; 2 y? (V); 2 yc? (V)], Vs zi^ [9 f?; 60 y? (V); 35 yd' (V) from same station] and 

 3 fd' '% [from the same stat. 12 f?; 9 y? (V); 2 y? (V); 5 y$ (V); i y<^ (IV); i y (III); i y (II)]; from the 

 same locality mature females were found eight times between -77 and '% and a single time ^/j^ night 

 [at this catch were taken 6 f?; 12 y?(V); 4 yc? (V); 6 y? (IV); 4 y$ (IV); 4y (III); i y (II)], young animals 

 (Vl seven times between 7; and '"/s and 9/jo, young animals (IV) 3/7, '% and 9/jo and Copep. (II — III) 

 only y/,0. 



At Disco Bay Lundbeck has % taken 160 mature females, 3 mature males, 3 young females 

 (V) and 5 males (V), 3 young females IV and 13 copepodites (III) and Bergendal at the same date 

 100 ? (VI), I c? (VI) and 3 y? (V). 



West of Iceland. In Denmark Strait and on the west coast of Iceland no specimens, which 

 were naturally referred to Ps. major, were observed; mature females of Ps. gracilis were only taken 

 at 3 stations (V.' 19-^°/, 1895) in the open sea and young ones (III — V) only '9/5, while specimens in 

 different stages, including mature males, of the Ps. clongatus s. s. were only found in "Dyrefjord" [30/5 

 1895. 6 f$ (partly with egg-balls attached to genital somite), 9 y? (V), 2 y? (IV), i fd*, 7 yS (V), i y$ 

 (IV), 2 y (III) and s/^ 1896 i f?]. The sample from '9/5 1895 V.' 100— o. St. 8, 63=56 Lat. N. 24=40 L. W. 

 contained 100 f?, 2 y? (IV), 7 fd*, 2 yc? (V), i y? (IV) and 2 y (IV), and that from ^o/, 1895 V.' 100— o fm. 

 St. 9 17 f$ and 15 fcf. 



North of Iceland. In the fjords north-west and north of Iceland A. Ditlevsen has ^5/3 1902, at 

 Hjalteneyri Ofjord gathered specimens of the clongatus type [i f?, 2 y? (V), i y? (IV); 2 yc? (IV); i y (III)]
