Belgium (v. Beneden). The Copenhagen Museum possesses specimens from the west coast of Norway, from 
Skager Rak, and Kroyer mentions it from Kattegat. Wilson records it from Cape Ann, Mass.; but when 
Brian (1898) records it from Pegli (Liguria) on Ovthagoriscus mola, the determination is probably wrong.

Wilson gives the full synonymy with discussion, and he is probably right in his interpretations. — 
Scott describes the ramus of fourth legs as three-jointed, which is correct, but in his fig. 3 on Pl. XVII and 
fig. 3 on Pl. XLVIII the ramus is only two-jointed. 
Occurrence. — Not taken by the “Ingolf’. 
Feeroes. Taken on Hippoglossus vulgaris in 1863 by Sysselmand Miller; 11 females, 5 males. 
Distribution. — On the gills of Rhombus maximus at various places in the British Islands from 
southern Scotland to Plymouth and Cornwall (various authors). Kroyer mentions it as taken on Rhombus 
maximus and LR. levis both from Kattegat and the North Sea, probably the west coast of Jutland; Steenstrup 
& Liitken received it from Bohuslan, where it has been found by Malm and Olsson. Wilson mentions a spe- 
cimen taken in Woods Hole, Mass., and a specimen from the mouth of Cynoscion nobilis captured at La Jolla, 
California.

The Copenhagen Museum possesses 2 old specimens marked Greenland, consequently West Green- 
land, “Skjeellax’’, consequently Salmo salar. 
At West Iceland this species has been gathered at Hvita in Borgarfjord on Salmo trutta by Mag. sc. 
B. Semundsson; 12 females, 1 male.
