that the full-grown individuals only in summer (the spawning- 
time) are to be found on the coastal banks, it seems to me more 
probable that the young stages are living at great depths where 
then also the full-grown ones are staying in the interval between 
spawning-times. 
Coryphaenoides rupestris (Gunn.). On the plate are depic- 
ted two very young Macrurids from the Norwegian coast. The 
one (fig. 3) has a total length of 54 mm., but the caudal 
part is incomplete. It was collected by the "M. Sars” in 
Hjørundfjord by a prawn-trawl at 400 metres. In all likelihood 
it has been captured in intermediate water-layers. The same 
catch contained namely four Myctophum glaciale and one 
Maurolicus miilleri, both true pelagic species. The larva is 
further closely allied to some Macrurid-larvae which by the 
“Arm. Hansen” in 1913 in the North Atlantic were taken bathy- 
pelagic above great depths. These Norwegian specimens will 
be more completely dealt with in a forthcoming paper on the 
above-mentioned Atlantic larvae. I shall here only offer some-- 
remarks on referring this stage (fig. 3) to Coryphaenoides 
rupestris. It shows considerable likeness to some small bottom- 
stages of this species of a total length 110—120 mm., the elongated 
ventrals and the plate-shaped, stalked pectorals not being considered. 
These are larval characteristics generally found in the pelagic 
Macrurid-larvae'). Of our Macrurs C. rupestris is the only one 
common in the fjords, Macrurus jabricii being a more Arctic 
form, and though occurring southwards as far as to the coast of 
Romsdal it does not enter the coastal plateau and the fjords. 
On the plate is as fig. 4 depicted a still younger larva. Together 
with four others of the same size (36—40 mm.) and a smaller 
but mutilated one (abt. 30 mm.) this larva was preserved on a 
glass labelled: “M. Sars” stat. 235—271. */s--1" 1906. — Stat. — 
235 is Borgundfjord near Aalesund and stat. 271 is N. 62° 51, — 
E. 5° 57, depth 123 metres. The other stations are all in the ~ 
vicinity of these, none is outside the continental plateau. As > 
will be seen from the report by DAMAS (1909 p. 265—68) several 
- 1), Ateleobrachium pterotum, a new genus and species of Macruridae 
established by GILBERT & BURKE (1912 p. 94, fig. 37) for a pelagic specimen, 
00 mm., from the Bering Sea, is merely such a larval form.
