The antennze somewhat shorter than the antennulz, the first joint a little shorter and thicker 
than the second, the third joint short, and its seta scarcely as long as the two last joints 
combined. Of the maxillule I have only found two sete. The second and third joints of the 
maxille proportionally pretty long; all joints smooth. The second joint of the maxillipeds 
shorter than the third one. The seta on the posterior angles of the first abdominal segment 
reach far beyond the caudal stylets, which are small and distinctly separated from the small 
third segment. The body not having quite reached its final shape, the relative length of 
the terminal sete of the caudal stylets cannot be indicated with full certainty, but they 
are probably half the length of the body. 
POST-LARVAL DEVELOPMENT. Unknown. 
HABITAT. The marsupium of Bruzelia typica Boeck from Norway. The species 
was discovered by Prof. G. O. Sars, who sent me one female and eight ovisacs mutually 
glued together, two of them with the lary described. Later on he presented our Museum 
with some specimens of the host taken at Mosterhayn in a depth of 150 fathoms, and in 
one of these specimens I found two ovisacs, beneath them the female represented, and 
behind this female eight ovisacs glued together in a lump (none of them containing larvee), 
but I am uncertain whether all these ovisacs were laid by the female found, or whether 
eight of them were not rather laid by a female which may have fallen out. At last I 
bought Prof. Sars’ whole material and found in one specimen a female (the largest), a male 
and four good-sized ovisacs mutually glued together. 
REMARKS. The species is nearly related to S. Holbdlli, yet both sexes distinguish 
themselves from it by several good characters, the female e.g. by the fringe of hairs on the 
frontal margin and by the hairs in front of the maxillipeds, the male by the structure of the 
first pair of legs. 
17. Sphzronella capensis n. sp. 
(PI. V, fig. 4a—4c; pl. VI, fig. la—id.) 
FEMALE. The only specimen (fig. 4a) was ‘52 mm. in length and 45 mm. in breadth, 
shortly ovate, broadest in front of the middle and scarcely as thick as broad. The head, 
which is well defined, and the genital area are both found on the ventral surface of the 
body, at some distance from the anterior and the posterior end respectively. The frontal 
margin naked. The antennule of medium length, with long sete, the terminal seta much 
longer than the whole antennula (fig. 1a). The antenne, the mouth, the maxillule and the 
maxilla much as in S. intermedia; the maxillipeds with a somewhat shorter, naked basal 
joint and with a pointed terminal joint, without distinct secondary spines. The sub-median 
skeleton with a moderately narrow list inside the maxilla, naked all over; behind the 
maxillipeds two transverse lists between the head and the trunk. The lateral margin of 
the head naked. The trunk naked; only one trunk-leg is supposed to be found. The genital
