low the three upper spines, the first (uppermost) of which is very 
prominent and peculiarly straight. Below the notch the cutting 
edge is densely armed with spines, two of which are much stouter 
than the others, and almost reach the size of the upper spine. The 
lower and outer part of the maxilla is densely furnished with hairs. 
The external shape of this species recalls Heteralepas (Para- 
lepas) peduncnlata (Hoek), and Heteralepas (Paralepas) percarinata 
Pilsbry; but the presence of scuta separates it from both of 
these forms. It is also nearly related to Heteralepas (Paralepas) 
Dannevigi, with which species it has the scuta in common; but the 
entire lack of a carinal crista in Heteralepas scutiger separates it 
from the named species, and moreover the structure of the basal 
segments of the rami of the cirri and the numbers of segments in 
the cirri, and the caudal appendages besides differ so much that 
the species must be kept apart. 1 ) 
Heteralepas (Paralepas) nodulosa n. sp. 
3 miles S. W. of Tueuran; 300 fathoms. 10/III 14. One specimen on a 
spine of Cidaris sp., together with Megalasma striatum, and 
Verruca Kr uger i. 
The capitulum is globular without carinal crista; the orifice is 
situated at the upper side of the capitulum and directed obliquely 
upwards, with feebly lobed margins. Scuta are indicated as triang- 
ular rudiments. The peduncle is sharply limited against the broader 
capitulum. The surface of the animal is finely transversally striped, 
and set with small, well defined, scanty, almost thornlike warts. 
The species (Fig. 37) is at once characterized by its small spines 
or warts, which are especially found on the capitulum, although 
they also occur on the peduncle. The animal is in aleohol of a 
dark brown colour, the peduncle a little lighter in hue. The thick 
outer layer is more transparent. The cuticle is transversally feebly 
wrinkled or striated, somewhat more prominently in the peduncle; 
this may be due to contraction. The peduncle is by an abrupt nar- 
rowing distinetly separated from the capitulum. 
Scuta are present as small chitinous triangular rudiments just 
below the orifice. They are only with difficulty traced. 
Possibly identical with Heteralepas (Paralepas) typica Nilsson-Cante 11 
(1921).
