valueless; two points in his good description quoted ought to be 
mentioned. When he said that the first joint of the "claw” of 
second thoracic legs is serrated along the front margin he is most 
probably in wrong; on the length of the outer ramus of the uropods 
as compared with that of the inner ramus he has not expressed 
himself so directly that one may be able to judge of the proportion 
between these dimensions with absolute certainty. In my specimens 
the inner ramus is from scarcely two and a half to nearly three 
times as long as the outer. That the Danish specimens belong 
to T. gracilioides Lilljeb. captured at three localities off the Swedish 
coast of Skagerak is, I think, quite certain, the only difference 
being that Lilljeborg says that in his females the inner ramus 
of the uropods is about twice as long as the outer. The question 
is whether L. gracilis Kr. and L. gracilioides Lilljeb. are identical; 
the specimen from Spitzbergen is somewhat larger than the spe- 
cimens from Sweden and Denmark, but the other points are men- 
tioned above, and having examined an enormous material of Lepto- 
gnathia (with numerous new species) from the deep sea around 
and from the coasts of Greenland, Iceland and the Færoes I have 
arrived at the conclusion that L. gracilioides, of which I possess 
sSpecimens from Denmark, Norway, West Greenland and the Kara 
Sea, is identical with L. gracilis. 
In 1898 G. O. Sars kindly presented our Museum with a 
number of Leptognathia named by him L. longiremis Lilljeb. The 
majority of the specimens are L. Sarsii H. J. H., 9 specimens 
belong to L. longiremis Lilljeb. but not Sars, 3 specimens to L. 
gracilis Kréyer. As the two last-named species are not mentioned 
in Sars's fine work, I can here add them to the fauna of Norway.
