Norwegian Solenogastres 43 
The coelomoducts are furnished with a bunch of small vesicule 
seminales anteriorly and with separated openings, as characteristic 
of the genus (fig. 63). 
A sensory organ, observable by dissection, is situated on the 
dorsal side between the pericardium and the end of body. 
In the cloacal cavity the wall carried some distinct folds 
which, however, were certainly due to the contraction, as they 
had a concentric direction round the aperture, not a radiating 
one like true branchial folds. 
The pharynx is long and muscular (fig. 62), and a short and 
rather wide dorsal oesophagus leads into the intestine. Into the 
radula sac debouch two tubular salivary glands, which are narrow 
anteriorly and become wider to the rear; they extend to a con- 
siderable length. The intestine has a dorsal coecum protruding 
above the pharynx as far as the brain, and on each side a series 
of hollow-shaped diverticula between the powerfully developed 
dissepiments (fig. 62). 
The sum of characteristics of this form shows entire conformity 
with the genus Anamenia NIERSTRASZ 1902, which differs from the 
nearly related Strophomenia only in the possession of a radula. Of 
the four species of Anamenia which were previously known three 
have a round body without dorsal keel, and the fourth, A. tri- 
angularis, has a very high one, which results in the body having 
a triangular section. The present species thus differs distinctly 
from all others in its thread-like dorsal ridge and its somewhat 
depressed body. In the brief diagnosis given by KorEN & 
DANIELSSEN, this dorsal keel is said to be richly beset with short 
thick spicules. This statement is liable to be misunderstood; the 
ridge does not differ from the remaining cuticula except by marking 
a line where the spicula are more crowded. The ridge is formed 
exclusively by the cuticula; the underlying tissue does not partake 
in its construction. 
Fam. Lepidomeniidae. 
This family is represented in the Arctic region by one species, 
Nematomenia arctica, described by THIELE from Spitzbergen, and 
the same genus also comprises a Norwegian form: 
Nematomenia banyulensis PRUVOT var. norvegica n. var.
