50 CRUSTACEA COPEPODA. II. 
off; third joint conspicuously broader than long, increasing in breadth from base to end, its terminal margin 
is partly concave, with a long, strong, curved spine on the anterior angle so that a kind of imperfect chela 
is formed; a small and thin spine is inserted on the end close at the strong spine mentioned. — Maxillul 
(fig. 2m) in the main as in the female, differing especially in having the apical robust sete on the three 
terminal branches rather long, and the palp seems to be unjointed. — Maxillee (fig. 2 n) with first joint ex- 
tremely broad, at the inner margin terminating in a triangular, robust process with its inner margin and 
the end serrate; the “claw” is robust, extremely broad at the base, and its terminal portion is strongly curved, 
lying on the posterior side of the process mentioned. — Maxillipeds (fig. 2 0) with the proximal, well chitin- 
ized joint somewhat flattened and consequently considerably broader than thick, and besides nearly twice 
as long as broad; it increases considerably in breadth from the base to much beyond the middle; the major 
part of its outer margin is rather convex, and at the distal part of the inner margin two very small, sharp 
protuberances are found; the inner, distal corner is produced into a strong, oblong-triangular, acute process; 
the claw is very robust, very thick at the base, and its distal half is extremely curved. — Each of the two 
anterior segments of the trunk has a pair of minute legs, a little longer than broad, and with a single seta 
or two small sete on the end. 
Length of the single male 1.93 mm. (caudal rami not included). 
Remarks. — This fine species is in general aspect rather similar to Lerneopoda longibranchiata 
Brian, by Wilson referred to his genus Levneopodina. But it is instantly distinguished from Brian’s species 
in having the posterior processes ventral to the ovisacs, while they are dorsal to the genital openings in the 
genus Lervneopodina. The female of the new species agrees with Levneopoda as characterized by Wilson; 
the male differs not only from the genus but from nearly all genera of the family in possessing two very 
distinct pairs of legs on the trunk. The difference between the two females hitherto known as to length and 
development of the maxilla is most noteworthy. 
Occurrence. — Not taken by the “Ingolf” but by the “Thor” and the “Michael Sars”’ at the following 
places, in both cases on Centrophorus squamosus. 
South of Iceland: Lat. 63°05’ N., Long. 20°00’ W., 920 m; the “Thor’’ (Dr. Johs. Schmidt), July 16, 
1903. One female without ovisacs at the pectoral fins of the host. 
South-West of the Feeroes: Lat. 61°07’ N., Long. 9°33’ W., 400 fathoms; the “Michael Sars’ (Cand. 
mag. Ad. Jensen), Aug. 14, 1902. One female with ovisacs and a male. 
72. Lernzeopoda Sebastis Kroyer. 
1863. Lerneopoda Sebastis Kroyer, Nat. Tidsskr. 3. Rekke, B. II, p. 353, Tab. XVII, fig. 7, a—h. 
Kroyer had two mutilated females; the poor condition of the preserved fragments of these speci- 
mens makes it impossible to add anything to his description or figures, and the species has never been found 
again. 
Occurrence. — Kroyer had 2 females from West Greenland; he found them in the branchial cavity 
of Sebastes marinus.
