If any conclusions with regard to the occurrence of the three mentioned types can be drawn 

 from the above, it must be that Ps. Dinjor is onh- found in the open sea in Davis Strait, probably 

 not at the surface, tliat Ps. rloigatus 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, 

 especiall\- in sj^ecies in which the manducatory limbs are rudimentar}-, onl\- live a comparatively 

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

 the pro])agation 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 Fseroes '^•.^ 1895 and in 4 samples '5 — ^'^ 1S96, 

 in the Iceland-Fasroe Channel at 3 stations n/j— '3/, 1895 and ^°\^ 1896, south-west of Iceland '3 ,, and
