CRUSTACEA COPEPODA. II. 9 
Dermatomyzon Claus. 
Only a single species has been found within our area. 
7, Dermatomyzon nigripes Brady. 
1880. Cyclopicera mgripes Brady, Mon. Brit. Copep. Vol. III, p. 54, Pl. LXXXIX, figs. I—IT. 
1899. Dermatomyzon — Giesbrecht, Asterocheriden, p. 7, 77, 101; Taf. 1, Fig. 4; Taf. 5, Fig. i—14. 
!IQt5. — — G. O. Sars, Account, Vol. VI, p. 95, Pls. LIX & LX. 
Occurrence. — Not taken by the “Ingolf’”’, but by Dr. F. Borgesen in May 1808. 
Feroes: Glyvenzs near Thorshavn, Strém6; 4 adult females. 
Distribution. — “Not unfrequently along the whole Norwegian coast, from the upper part of the 
Christiania Fjord to Vads6, in moderate depths” (G. O. Sars). Recorded from the Norway Islands at Spitz- 
bergen, between algze (G. O. Sars), from lat. 76°17’ N., long. 21°36’ E.., 60 fath. (Th. Scott), and from Franz 
Joseph Land off Hast Glacier, Cape Flora (Th. Scott). At Great Britain found in many places and in moderate 
depths, from Shetland to the Channel, f. inst. near Plymouth (various authors), finally at Naples (Giesbrecht). 
— Whether D. elegans Claus from Triest (Claus) and Pas de Calais (Canu) is the same species the future 
must decide. 
Scottocheres Giesbrecht. 
Of this genus only a single form has been captured. 
8. Scottocheres gracilis n. sp. 
(PL. I, figs. 5 a—5 d.) 
Female. — This species is similar and closely allied to S. longifurca Giesb., but differs from Gies- 
brecht’s representation in some particulars. — Head and thoracic segments nearly as in S. longifurca. — 
Genital segment (fig.5d) more narrow than in that species, being half as long again as broad, and the anterior 
broader part is very much shorter than the part behind the lateral teeth, as these originate slightly behind 
the end of the anterior third of the segment, while in S. longifurca they are placed slightly before the middle; 
finally each lateral tooth has on the interior margin an angular protuberance wanting in the other species. 
Second abdominal segment (fig. 5 d) not half as long as the first and nearly half as long again as the third, 
which is very slightly broader than long, thus more slender than in S. longifuvca. Caudal rami slightly more 
than twice as long as the terminal segment and slightly shorter than second and third segments combined, 
five times as long as broad, thus longer and more slender than in S. longifurca. 
Antennule (fig. 5 a) agree with those in S. elongatus and differ from S. longifurca in having third 
and fourth joints completely fused; the eight distal joints are proportionately more slender and longer than 
in S. longifurca as figured by Giesbrecht. — The length of the sipho, maxille (fig. 5 b), and maxillipeds (fig. 5 c) 
nearly as in that species; the same is the case with the setee on the endopod of third legs. In the specimen the 
left fifth leg preserved reaches conspicuously beyond the lateral tooth of the genital segment, while in Gies- 
brecht’s figure these legs terminate somewhat before the base of these teeth. 
Length 1.05 mm.
