and 28 / 8 at Svavadilvig [2 f ., i y? (V); i yd* (IV), 3 yd* (V)]. Lundbeck has /. 1892 taken 14 f$ (two 

 with egg-ball and one with spermatophor), 3 y$ (V), 2 yd* (V) at Skutulsfjord and 2 3/ 8 ? in Gunolfsvig 

 (N. East Iceland) 50 f?, 5 y? (V), 10 yd 1 (V) and i yd* (IV). 



South-West of Iceland. To the south-west of Iceland 10 mature females, 5 y<j? (V), 3 mature 

 males and 5 young males (V) were found J 3/ 6 1896, St. 80, P. 100 o fin. 6io2 Lat. N. 2g32 Long. W. 



South of Iceland. To the south of Iceland a single male was taken by the Ingolf Exp. (7/ 8 

 1896, Cyl. 32, 6345 Lat. N. 2237 Long. W. 2 ?; 2cT); 8 /s 1896 a mature female of Ps. gracilis, and from 

 J 3/ 5 19/5 1896 at three stations females of Ps. elongatus were taken; of the latter young animals (V) 

 were taken at 3 stations ( 6 / 5 $ l / s ), y . (IV) at a single station (3i/ 5 1896) and young animals (III) 3/. 1895 

 and 3i/ 5 1896. The East Greenland Exp. 1900 has taken a few mature and young females south of 

 Iceland 2 5/ 9 . 



In the Icelandish fjords adult males have been taken several times by different collectors. On 

 the north coast it was only taken once [Ingolf J /s 1896 Selvik in Skagafjord 6558 L. N. i95O L. W. 

 PI. 4 y? (V), i fd 1 , 5 yd* (V), 7 yd* (IV), 10 y (III) and 2 y (II)]. On the east to west coast males were 

 taken 3 times ( J 3/ 5 26 / 5 1902), and females as well as juniores (stage II V) were jn several samples 

 found common from '3/ 5 26 / 5 . 



South-East of Iceland. In the Iceland-Fseroe channel south east of Iceland Ps. gracilis 

 were taken in four samples between "/ 5 16 / 5 1895 and 2 / 5 1896, and Ps. elongatus (f c?) in four samples 

 ("As l6 /s z ^95 an d 20 /s J 896); young animals (IV V) were taken three times ("/ 5 '3/ 5 1895 and 2 % 1896). 

 Several males were found in a single sample from "/ 5 St. i, V. 1 500 fm. 623O Lat. N. 82i L. W., 

 including 140 f?, 23 y? (V), 8 y? (IV), 30 id 1 , 20 yd" (V) and .5 yd 4 (IV). From St. 3, I2 / 5 , V. 1 100 o fm. 

 ii f. and i fd* were found and from St. 4, r 3/ 5 1895, V. 1 100 o fm. 64^7 L. N. iii2 L. W. 37 f?, 3 y? (V), 

 i y? (IV), 2 fc? and 4 yd 1 (V). From St. 57, 20 / 5 1896, V. 1 100 o fm. 6337 Lat. North i3O2 Long. West, 

 i f?, i y? (V) and 2 id* were secured. 



North-East of Iceland. To the east and north-east of Iceland as far north as Jan Mayen 

 specimens (f .) of Ps. gracilis were found in four samples, taken between IO / 7 and 2 5/ 7 1896, and Ps. 

 elongatus in six samples ( IO / 7 2 5/ 7 ); young animals (IV V) of the former type from 3 Stat. ( IO / 7 2 5/ 7 ) 

 and of the latter from 9 Stat. ( IO / 7 2 V 7 1895); the following stage (III) was taken at 6 Stat (V 7 2K /s)- 



The East Greenland Expedition 1900 has from 2I /6 to 2 / 7 in the Norwegian Sea between 63i6 

 Lat. North ii4 Long. East and 723O Lat. N. 64i Long. W. collected a few samples containing this 

 species (type: gracilis or elongatus} all taken at the surface (F. or G.). 



The mature female was only taken once ( 2I /6 12 p. in. F. 33, 64^7 Lat. North o5i Long West); 

 young animals (V) were taken in 7 samples, including that from the most northern station, young 

 animals (III IV) were found in four samples. As the species was only taken in few specimens, in 

 altogether 7 samples, though one sample was taken each hour day and night from 2I /6 to 10 / 7 as fat- 

 north as 7428 Lat. North (i536 Long. West), there is good reason to regard it as extremely scarce 

 at the surface at the season and in the region mentioned. 



The expedition has taken the Ps. elongatus a few times in Nansen's closing net.
