East and South-East of the Faeroes. To the east and south-east of the Faeroes mature females 

 of Ps. gracilis were only taken 7/. 1895 and 6 / 5 1896, while those of Ps. elongatus were taken in 3 

 samples (5/ s and l 9/ 8 1895) and in 9 samples by Ingolf 1896 (4/ 5 _ 6 / 5 and l6 / 8 ). Mature males were taken

 1896 (4/ 5 — 6 / 5 ; l6 / 8 — 17/3), young animals (IV) only in 5 samples (4/ s — 6 / 5 and x 7/ 8 1896), jun. (Ill) in 3 

 samples (4/ 5 , 6 / 5 , i7/ 8 1896) and juniores (II) M s and I2 / 8 1896. 



E. Bay has «/ 6 1891 58^3 Lat. N. 2°o8 L W. taken 50 f?, 31 y? (V), 16 y? (IV), 3 fc?, 16 yc? 

 (V), 19 yc? (IV), 9 y (III) and 2 y (II). Morten sen has 3/ 6 1899 at Kalbarsfjord, the Faeroes, 40 — 10 fm. 

 taken 3 females with spermatophores and Rink has l8 / 3 1848 at the 0rkney Islands taken 6 f<j>, 4 y<j>, 

 3 fc? and 3 yc?. 



If any conch;sions with regard to the occurrence of the three mentioned types can be drawn 

 from the above, it must be that Ps. major is only found in the open sea in Davis Strait, probably 

 not at the surface, that Ps. elongatus is often found at the very surface, most common in samples 

 taken comparatively near the coast, though in no wise scarce in those from the open sea, and that 

 Ps. gracilis seems to be a more northern and more oceanic form. 



Propagation. As it is generally recognised that the mature males of the pelagic copepodes, 

 especially in species in which the manducatory limbs are rudimentary, only live a comparatively 

 short time, we are right in concluding that the seasons in which we find mature males are those of 

 the propagation of the species; specimens with spermatophores attached to the genital somite and 

 with egg-balls indicate the same. 



Mature males have been found south-east of the Faeroes 6 / 5 1895 and in 4 samples 4/ s — 6 / 5 1896, 

 in the Iceland-Faeroe Channel at 3 stations IJ / 5 — - L M S 1895 and 20 / 5 1896, south-west of Iceland r 3/ 6 and 

 7/ 8 1896, in Denmark Strait at 2 stations x 9/ s — 2 °/ 5 1895, in various Icelandish fjords, in 5 samples 3/ 5 — 

 3°/ 5 1895 — 1 9°2, at the 0rkney Islands l8 / 3 1848; 3/ 6 1899 a female with spermatophor was taken at the 

 Faeroe Islands; IT / 6 1891 mature males were taken south-east of the Faeroes; north-east of Iceland (as 

 far north as 66° Lat. North) mature males were taken 2 5/ 7 1895 (+ females with spermatophores)
