COPEPODA 6l 



North), in the Polar Sea as far north as 72^30 Lat. North (64i 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 account 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. major, at four stations from Y 7 "/? ^95i Ps. gracilis at five 

 stations from 25 /6 28 /7> an< ^ P S - elongatus from a single stat n / 7 - Of the copepodites (St. V) specimens 

 of Ps. major have been taken at 2 stat. ( 26 /e r / 7 ), of Ps. gracilis at 3 st. ( r / 7 28 / 7 ) and of Ps. elongatus 

 at 2 stat. ( r / 7 - "/?)) f tne copepodites (St IV) Ps. major was taken at 3 stat ( 26 /6 1 / 7 ), of Ps. gracilis 

 at 2 stat. ( 6 / 7 2S / 7 ) and Ps. elongatus at 2 stat. ( r / 7 "/?) At a single station ( r / 7 St. 29, 65i7 Lat. 

 North 5542 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 2000 fathoms, Bergendal and 

 Lundbeck 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. elongatus type. From 

 "Jakobshavn" 2 mature males [from the same sample 50 f .; 5 y$ (V); 4 yd 1 (V); 3 yd* (IV); i y (III)) 

 were taken 28 / 8 , mature females were taken at 3 stations ( 2I /s 28 /g), young specimens (V) at same 3 

 stations and Cop. (Ill IV) at a single stat. ( 28 /s) only. From Egedesminde 2 mature males were taken 

 2 s/ 7 [from same stat. 6 f?; 2 y? (V); 2 yd 1 (V)], 4/ 8 2 f d 1 [9 f? ; 60 y? (V); 35 yd 1 (V) from same station] and 

 3 fd 1 I0 /s [from the same stat. 12 f?; 9 y? (V); 2 y . (V); 5 yd* (V); i yd 1 (IV); i y (III); i y (II)]; from the 

 same locality mature females were found eight times between 2I / 7 and '% and a single time 9/ IO night 

 [at this catch were taken 6 f?; 12 y? (V); 4 yd 1 (V); 6 y? (IV); 4 yd 1 (IV); 4 y (III); i y (II)], young animals 

 (V) seven times between 3/ 7 and IO / 8 and 9/ IO) young animals (IV) s/ 7 , IO / 8 and 9/ IO and Copep. (II III) 

 only 9/ 10 . 



At Disco Bay Lundbeck has 6 / 9 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. 1 I9 ~ 2 % 1895) in the open sea and young ones (III V) only '9/ 5 , while specimens in 

 different stages, including mature males, of the Ps. elongatus s. s. were only found in "Dyrefjord" [3/ 5 

 1895. 6 f$ (partly with egg-balls attached to genital somite), 9 y$ (V), 2 y? (IV), i fd 1 , 7 yd* (V), i y6* 

 (IV), 2 y (III) and s/ 6 1896 i f?]. The sample from '9/ 5 1895 V. 1 100 o. St. 8, 6356 Lat. N. 244O L. W. 

 contained 100 f?, 2 y? (IV), 7 fd 1 , 2 yd 1 (V), i y? (IV) and 2 y (IV), and that from 2 % 1895 V. 1 100 o fm. 

 St. 9 17 f$ and 15 fd 1 . 



North of Iceland. In the fjords north-west and north of Iceland A. Ditlevsen has 2 s/s 1902, at 

 Hjalteneyri Ofjord gathered specimens of the elongatus type [i f., 2 y$ (V), i y$ (IV); 2 yd* (IV); i y (III)]
