As recorded above 2 of the specimens from St. 1a carry their 
ova. In "On propagation and early development of Euphausiidæ” 
in "Archiv for Mathematik og Naturvidenskab”, vol. 20, 1898, No. 
11, p. 9, G. 0. Sars mentions but 4 species carrying their ovisacs, 
viz. Nyctiphanes Couchii (see also Holt & Tattersall, Schizop. from 
the N.E. Atlantic Slope, Ann. Rep. Fish. Ireland, 1902—03, No. 4 
(1905) p. 104, Pl. 17, fig. 2), N. australis, Nematoscelis microps 
and Stylecheiron carinatum. Sars says "it is.... very probable, 
that these cases are quite exceptional, and that in the far greater 
number of Euphausiidæ the ova are at once ejected into the water”. 
I have from the literature not been able to find later additions 
to Sars' list,

Nematoscelis megalops carries, as is shown by the figure (fig- 2), its 
ova in an ovisac pointed in front; seen from below it seems to be
