We have thus from this station 1 spec. of the youngest larval stage, 
and 2 of a somewhat older stage. " 
The youngest stage agrees entirely, as far as I have been able to 
see without dissection, with BJörck’s description of this stage in Arkiv 
f. Zoologi, vol. 7, Nr. 15, 1911, p. 4 seq. (Bidrag til Kånnedomen om De- 
capodernas Larveutveckling, 
1, Pasiphaea); the rostrum, 
however, is less pointed on 
the whole, being rounded with 
a sharply defined point, as 
here shown in the older stage. 
This older stage is of an 
age between that of the oldest 
and the youngest described 
by Bsörck 1. с. Length abt. 
10mm. which corresponds well 
enough to the length of 9mm. 
for the youngest stage, and 
11—12 for the oldest (BJörck). 
I must here admit that my 
drawings are not as good as 
I could have wished. On being 
placed in glycerine, which I 
always use for specimens to 
be drawn, the legs swelled up

quite correct; in addition, I 
found considerable difficulty in determining the articulation. The 
shape of the antennae is between that of the 1. and that of the last 
larval stage. There is a very small exopodite on mxp 1, and a slighly 
larger one on mxp 2; i. e. about the same as in the youngest stage. 
Mxp 3 is about the same length as the foregoing, but the exopodite is 
longer. With regard to pl—p5, nothing particular to remark, save that 
på is, as in the adult form, longer than p4. There are, however, at least
