individuals that have evidently just become ovigerous, it is not 
improbable that this species like Crangon vulgaris (ef. page 26) 
has two hatehing periods in the year. The ova spawned in the 
early part of the summer become fully developed towards the be- 
oinning of autumn, new spawning subsequently takes place, and 
the young from this second lot of ova are hatehed out in the fol- 
lowing spring. Unfortunately I am without material from the 
autumn and am therefore not in a position to elucidate this 
question properly. 
Maturity, &c.: NORDGAARD brought back from the Kamstad- 
fjord (47: 1899) a berried specimen, with very highly-developed 
ova, whose length was only 37 mm. This is the smallest ovigerous 
individual of this species in the whole of the copious material in 
the Bergen Museum. All other ovigerous specimens were as å rule 
several millimeters larger. 
The largest specimen measured had a length of 93 mm. [S/s 
*Michael Sars”. Jan Mayen */s 1900, 50—70 fathoms]. This too 
was å berried female. 
The small newly-hatehed larvae found amongst the ova on 
some ovigerous specimens in the latter part of April had å length 
of 3 mm. From the middle of April we have several small speci- 
mens partly a little under and partly a little over 30 mm. These 
small specimens which corresponded moreover in structure with 
the larger individuals were most probably hatched in the pre- 
vious year. 
We have, as previously stated, found specimens in March that 
were no more than 37 mm. long, but had highly-developed ova: 
and it is not unlikely that Sabinea septem-earimata becomes mature 
the year after hatehine. However the larger number of ovigerous 
females were, as stated, several millimeters longer: so that the age 
of maturity may be supposed not to commence as å rule, till the 
second year after leaving the egg. 
Sabinea sarsi, SmitH. 
Habitat: I have found this species not only in the Brevik- 
fjord (60—70 fathoms) but also on the south and west coasts of 
Norway (Ferkingstad islands 30—50 fathoms; Herløfjord near Ber- 
gen 60—100 fathoms and west of Stat 150 meters), and Nor»b-
