292. if K. STEPHENSEN. 
In order to make sure that I had not after all here to deal with 
small specimens of Hal. fulv. I examined several specimens of that spe- 
cies at about the same size; these were certainly somewhat different 
from the grown specimens, there being for instance at times small teeth 
in the emargination of the telson, while the tooth on the 7. joint of 
the mesosome can be somewhat small; in spite of this, however, the 
two forms were easily distinguishable; there were no real intermediate 
forms. 
The specific name of bispinosus refers to the fact of there being 
only 2 teeth in the dorsal line. 
73. Calliopius laeviusculus Kr. 
Conspectus p. 179, 426. ; 
Bredefjord St. 66, 9—11 m., 7 spec. (?); St. 89, 16—17 m., 6 
spec. (?); St. 104, 7—20 m., 8 spec. (?); St. 123, 5—10 m., 1 spec. 
The specimen from St. 123 is determined with certainty; 1t mea- 
measured 11 mm., the others only about 8 mm. And with regard to 
the others, I] am not certain as to the correctness of the deter- 
mination, as they closely resemble C. Rathkei, a point which Hoitmes 
remarked some years back in the case of the smaller specimens 
(Bull. Bur. Fisheries, Washington, vol. 24, 1904, p. 494). The terminal 
lappet of the last peduncular joint. of the ant. 1. is too short, and the 
hook on the 3. epimeral plate of the metasome is of an intermediate 
shape between those of the two species.

Kvanefjord St. 21. surface, 1 spec, (?). — Bredefjord St. 61, 
12,5—13 m., 1 spec.; St. 85, surface, 1 spec. 
The specimens from St. 61 and 85 are doubtless correctly deter- 
mined; there is some uncertainty, however, in the case of that from 
St. 21, which, with the longer lappet on ant. 1, resembles C. laevius- 
- culus; the hook on the 3. epimeral plate of the metasome, however, 
agrees with Sars’ figure (Account, Pl. 157, fig. 2). This species has, 
by the way, only been found in W. Greenland near Disko. 
75. Rhachotropis aculeata Lepechin.

m., 6 spec.; St. 109, 125—140 m., 1 spec. — Skovfjord St. 156, 70— 
140 m., 2 with ova. 
Strangely enough, this species is not hitherto known from between 
Julianehaab (abt. 6034° N.) and abt. 66%° N.
