58 CRUSTACEA COPEPODA. I. 
shape. — The maxillipeds (figs. 3 b and 3 e) originate a little longer from the proboscis than from the maxille; 
as already mentioned each maxilliped is situated on the end of a large, oblong, subconical part, which looks 
somewhat thin-skinned, projects freely forwards and contains muscles (shown in fig. 3 e); the first well 
chitinized joint is very small, oblong, broadest at the middle; second joint is slender and terminates in a 
normal claw, below which an accessory short spine is observed. 
Length of the body 5.1 mm., of the maxille 10.5 mm. 
Remarks. — This is the most interesting species among the new forms of parasites from the “Ingolf”’ 
area; in the remarks on the genus reference is made as to the most deviating features. 
Occurrence. — Secured by the “Ingolf”’ at a single station. 
Davis Strait: Stat. 35: Lat. 65°16’ N., Long. 55°05’ W., 362 fathoms, temp. 3°.6; 1 female firmly 
fixed on a scale on the front of Macrurus Fabricit. 
Brachiella Cuvier. 
Of this genus only a single species has hitherto been found in the “Ingolf’’ area, but some two or 
three of other forms taken at Scotland may probably later be found at the Feeroes.

Occurrence. — Not taken by the “Ingolf”’. 
This species lives on the gills of Hippoglossus vulgaris and H. pinguis. It has been taken several 
times at West Greenland; special localities are Godhavn, Lat. 69°14’ N. (Olrik), and Julianehaab, Lat. 60°43’ N.

Distribution. — Shetland (Wilson); North Sea (T. & A. Scott); Roscoff (C. Vogt); Storeggen, 
west of Norway (Olsson) ; Kattegat (Kroyer). Finally Woods Hole region, Mass. (Mary Rathbun) and Georges

(Anchorella Cuvier, Kroyer). 
This genus taken in the sense of T. & A. Scott (1913) comprises 5 species from our area, and 2 among 
them are new, found on deep-sea fishes. In 1915 Wilson divided the genus into 4 genera, using especially 
characters drawn from features in the anterior free appendages, viz. whether the antennz are uniramose 
or biramose, the maxillule bipartite or tripartite, the antennule 3-jointed or 4-jointed. While the two first- 
named characters are always sharp, the joints in the antennule are sometimes difficult or perhaps impossible 
to count with certainty. My two new species have the antennze biramose and therefore they cannot belong
