maxille. Hach maxilliped proceeds from a chitinous list (fig. 1 e,h), projecting between the 
bases of the maxilla. The proximal part of the abdomen two to two and a half times 
broader than the distal part. Hach of the triangular caudal stylets (fig. 1g, t) has four 
setze, the foremost of which is short, the apical one moderately long. 
MALE. A well developed specimen is 196 mm. long and ‘11 mm. broad — thus 
good-sized in proportion to the female (fig. 1c: fig. 1a). So the body is a good deal longer 
than broad (fig. 1i). On the ventral side, stretching from the base of the antennule outside 
the maxille, the maxillipeds and the legs, backward towards the abdomen, and from the 
appendages towards the lateral outline, are found a comparatively small number of irregular 
stripes or grooves. On the basal part of the first pair of legs we see some irregular pro- 
jections and taps; similar though blunter taps or knots are spread more scantily over the 
dorsal side of the animal, whereas the frontal part is closely covered with larger knots. 
Antennule shorter than in the following species. The basal joint of the maxillipeds longer 
than that of the maxillz and more robust than in the following species. In the second 
pair of legs the apical spine on the inner branch is frequently somewhat curved, but not 
hooked. Of the setze on the caudal stylets, the apical one is thick and longer than the 
others. — A frontal thread was found in a few cases; it was about as long as the animal 
(fig. 1 ¢), simple and somewhat dilated towards the distal end. 
EGGS. They are very large (fig. 1d compared with fig. 1a), and are deposed in a 
large, loose, irregular lump, or in two (or very rarely three) lumps; the greatest number 
found is forty-two, the usual number is about thirty. 
LARVA (fig. 11). Length of the body (except caudal sete) 22 mm., which shows 
that it is longer than the male, though its volume is somewhat smaller. Cephalothorax 
oval, somewhat longer than broad. The front has a transverse band which curves backward, 
ending at a short distance from the base of the antennule. Antennule 3-jointed; olfactory 
seta at least double their length, reaching a little behind the middle of the cephalothorax. 
Antenne of medium length, 3-jointed; basal joint broad and longer than broad, about the 
same leneth as the second joint; third joint short, terminating in two or three sete, one of 
which is stout and as long as the second and third joints together. Second and third joints 
of the maxillipeds of about equal length. The longest seta at the hindmost angle of the 
first abdominal segment a little longer than the second segment. Each caudal stylet fur 
nished with five setee, one of them a little longer than the abdomen, two of the others a 
little longer than the last segment plus the caudal stylets. (See besides the diagnosis of 
the genus). 
POST-LARVAL DEVELOPMENT. Unknown. 
HABITAT. On Metopa Bruzelii (Goés) from two localities near the western coast 
of Greenland. In a glass labelled: »Godthaab, deep water [probably 40—60 fathoms], in 
Sertularia, Holboll«, were found numerous specimens of Met. Bruzelii (Goés) and of M. sinuata 
G. O. Sars, as well as a number of specimens of M. longicornis Boeck, M. longimana Boeck
