Kroyer is quite right in separating this species from S. salmonea l,., and in 1863 he published diag- 
noses (in Latin) of both species. Especially by the size and direction of the head together with the orbicular 
bulla placed on a long or at least moderately long stalk S. Carpionis is instantly distinguished from S. sal- 
monea. 
Occurrence. — Taken by the “Ingolf’’ at a single place. 
West Greenland: Sukkertoppen (Lat. 65°25’ N.); on a gill-arch of Salmo alpinus; 1 female (together 
with Salmincola alpina Olss.) 
Kroyer records it from West Greenland and Iceland on what he names Salmo carpio — in reality 
Salmo alpinus —, but without special localities. It has been found numerous times at West Greenland on 
S. alpinus, on the inner side of the operculum or — and sometimes in large number — on the tongue and 
the roof of the mouth; special localities are: Godhavn (Lat. 69°14’ N.), Fiskenzes (Lat. 63°05’ N.), and Ju- 
lianehaab (Lat. 60°43’ N.). (The Rev. P. H. Sorensen in Julianehaab has sent to our Museum specimens 
taken on Salmo sp. and besides a specimen according to the label taken on Sebastes marinus, which seems 
somewhat improbable, though perhaps possible). — In East Greenland the parasite has been taken at two 
places, viz. at Danmarks O (Hekla Havn, Lat. 70°27’ N.) (Wesenberg-Lund 1895), and on a large “Salmo 
salvelinus”’ taken by the Danmark-Exped. in the large lake behind the Hvalrosodde, Lat. 76°55’ N. (K. 
Stephensen). 
At Iceland S. Carpioms has been taken some four times; the only special locality noted is Ofjord, 
North Iceland, where it was found on Salmo alpinus.

Professor Dr. Jagerskj6ld, Director of the Museum in Goteborg, has most benevolently lent me 
Olsson’s type-specimens of Lerneopoda alpina, for which I beg him to accept my sincere thanks. A direct 
comparison of these specimens with my figures and the specimens from Greenland and Iceland shows the 
most complete agreement not only in general outline but in antennule, maxillule, maxillipeds and above 
all in the antennz. Olsson’s figure of the whole animal is not good, and as to general shape of the body and 
the insertion of the ovisacs my animals agree with Wilson’s figure of S. oquassa. 
Cephalothorax is, as said by Wilson, “narrow and much longer than wide, forming with the trunk 
a crescent or semicircle’, and seen from in front it agrees with his fig. 37; the trunk is “pear-shaped, strongly 
narrowed anteriorly but without a definite neck; squarely truncated posteriorly’. — The ovisacs vary both 
in Olsson’s types and in the numerous specimens from the “Ingolf’’ area very much in length and relative 
thickness, from being as long as trunk plus head to a little shorter than the trunk.
