All these evidently belong to one and the same species. The two 
oldest stages have a spine below (in front of) the anus, this spine, however, 
I have not been able to discover in the youngest stage. The oldest stage 
is that described and drawn in greatest detail; in the case of the others, 
I have only mentioned and shown the features in which they differ from 
the oldest stage. : 
Youngest stage (Fig. 8). 5—6mm. In ant. 1, the endopodite is very 
small, the peduncle still consists of but two joints, and has no spine on 
the underside. In ant. 2 the flagellum is half as long as the squama, 
terminating in a point with 
spines. Mxp. 1—3 are as in the 
next stage, as also pl1—p2, the ex- 
opodite, however, lacks natatory 
setae; this stage must therefore 
probably be described as an old 
Zoea. P3—p4 are cleft without ar- 
ticulation, p5, on the other hand, e 
lacks the exopodite. The pleo- Be 
poda are apparent asa very slight 
bulge on the ventral side. In the 
uropoda, there is still no arti- Are 
culate connection between the T+Up 
branches and the peduncle, the ‘Fig. 8. Spirontocaris-larva Nr. 3, 1. stage. 
outer ramus has a few, the inner 
ramus only two, pennate bristles. The telson is fairly broad, with a spine 
on either side. The posterior edge is slightly convex, and armed with 7 pairs 
of spines, of very characteristic lengths. Counting from the centre we 
find Nr. 1 very small, Nr. 2 abt. 3 times as long, and Nr. 3 twice as long 
as Nr. 2; Nr. 2 slightly longer than Nr. 2, Nr. 5 a little longer than Nr. 
3, and Nr. 6 again a little longer. The tip of Nr. 7 is lacking, so that 
its length cannot be seen; it would seem, however, to have been about 
the same length as Nr. 6.
