and 28 / 8 at Svavadilvig [2 f$, 1 y? (V); 1 yd 1 (IV), 3 yd* (V)]. Lund beck has 2 5/ 5 1892 taken 14 f°. (two 

 with egg-ball and one with spermatophor), 3 y°. (V), 2 yc? (V) at Skutulsfjord and 2 3/ 8 ? in Gunolfsvig 

 (N. East Iceland) 50 fft 5 y? (V), 10 yc? (V) and 1 yc? (IV). 



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

 males and 5 young males (V) were found r 3/ 6 1896, St. 80, P. 100 — o fm. 6i°02 Lat. N. 29°32 Long. W. 



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

 1896, Cyl. 32, 63°45 Lat. N. 22°37 Long. W. 2 °.; 2<?); 8 /s 1896 a mature female of Ps. gracilis, and from 

 J 3/ 5 — J 9/ 5 1896 at three stations females of Ps. elongatus were taken; of the latter young animals (V) 

 were taken at 3 stations ( 6 / 5 — 31/5), y? (IV) at a single station (3 x / 5 1896) and young animals (III) 3°/ s 1895 

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

 Iceland 2 5/ g . 



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

 the north coast it was only taken once [Ingolf x / 8 1896 Selvik in Skagafjord 65°58 L. N. i9°50 L W. 

 PI. 4 y°. (V), 1 fc?, 5 yc? (V), 7 yc? (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 in several samples 

 found common from T 3/ s — 26 / 5 . 



South-East of Iceland. In the Iceland-Faeroe channel south east of Iceland Ps. gracilis (i%) 

 were taken in four samples between TI / 5 — l6 / s 1895 and 2 °/ 5 1896, and Ps. elongatus (f°. — c?) in four samples 

 ("/s — l6 /s l8 95 and 20 /s l8 96); young animals (IV — V) were taken three times ("/ 5 — ^/ s 1895 and 20 / 5 1896). 

 Several males were found in a single sample from ri / s St. 1, V. 1 50—0 fm. 62°30 Lat. N. 8°2i L. W., 

 including 140 f?, 23 y? (V), 8 y? (IV), 30 fc?, 20 yc? (V) and 5 yc? (IV). From St. 3, I2 / 5 , V. 1 100-0 fm. 

 11 f°. and 1 fc? were found and from St. 4, r 3/ s 1895, V. 1 100—0 fm. 64°07 L. N. n°i2 L. W. 37 f?, 3 y°. (V), 

 1 y? (IV), 2 fc? and 4 yc? (V). From St. 57, 20 / 5 1896, V. 1 100— o fm. 63^7 Lat. North i3°02 Long. West, 

 1 f$, 1 y$ (V) and 2 fc? 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 I0 / 7 and 2 5/ 7 1896, and Ps. 

 elongatus in six samples ( I0 / 7 — 2 5/ 7 ); young animals (IV— V) of the former type from 3 Stat. ( I0 / 7 — 25 / 7 ) 

 and of the latter from 9 Stat. ( I0 / 7 — 2 V 7 1895); the following stage (III) was taken at 6 Stat. ( I / 7 — 28 / 8 ). 



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

 Lat. North i°i4 Long. East and 72°30 Lat. N. 6°4i 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. m. F. 33, 64°i7 Lat. North o°5i 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 I0 / 7 as far 

 north as 74°28 Lat. North (i5°36 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.
