a small exopodite on pl—p2; I have not been able to discover any 
such on p3. On the ventral side at the base of p4—pd (i. e. at each pair) 
are a pair of short appendices, apparently inarticulate, which I have 
not been able to determine. — Length abt. 11 mm. 
Spirontocaris (Fabricii?) juv. (Fig.14). 
Bredefjord St. 61, 12,5—13 m. (22/vir), 3 spec.; St. 66, 9-11 
m. (23/уп) about 15 spec.; St. 69, 16—17 m. (31/vm), 7 spec.; St. 104, 
7—20 m. (5/vıu), 50 spec.; St. 123, 5—8 m. (25/vıu), abt. 10 spec. 
At these stations, some specimens of a Spirontocaris juv. were 
taken. The shape of the telson is very characteristic. Length 10 mm. 
With regard to general appearance nothing is to remark. The 
carapace is cylindrical, with a fairly long rostrum (nearly as long 
as the eye minus the facetted portion). Behind the rostrum are 2 (in 
cases 3) spines, but there is no supra-ocular spine. There is, however, 
one beneath the eye, and one on the anterior lower corner of the cara- 
pace. There is a distinct median eye. The sides of the telson are ab- 
solutely parallel, with three pair of lateral spines, the middle pair, how- 
ever, in some cases lacking, while at the posterior corners there is 
one short spine and one long. There are two ciliated setae on the me- 
dian portion of the telson’s posterior edge, with two setae between 
these and the corner spines. Both oral parts and pereiopoda show that 
the stage in question is fairly far advanced. There is a gill at the base 
of mxp 3 and pl—p5; exopodites on pl1—på. 
There would seem little room for doubt that this is the young stage 
of Sp. Fabricu. There are four species without supra-ocular spines, 
ciz.: Sp. Gaimardii, Sp. Fabricii, Sp. pusiola and Sp. macilenta. Sp. pu- 
siola is out of the question here, as it is not found in the material, and 
Sp. Gaimardii may be excluded for a similar reason, as it has not been 
taken in Bredefjord, where all the young stages in question were pro- 
cured, but only in Kvanefjord, and there but a single specimen. Sp. 
macilenta is likewise barred, being a deep sea species. 
There remains then only Sp. Fabricii, and that the specimens in 
question should belong to this species is rendered the more probable 
by the fact that Sp. Fabricii was taken in great numbers everywhere, 
especially at those stations where the young stages were found.
