Our knowledge regarding the distribution of the Crustacea at 

 East Greenland is very imperfect, only a few, very restricted areas 

 having been investigated; for West Greenland we have much 

 better information. Nevertheless, even there it is only the coastal 

 animals whose distribution can be indicated in any way completely. 

 The only work existing on the Greenland Crustacea with all the 

 localities known at the time is that by H. J. Hansen mentioned above 

 on the Malacostraca of West Greenland from 1887. By merely 

 turning over the leaves of this \vork we can at once see, whether a 

 species belongs to the coastal belt, or if it is a deep-water form 

 ( — at that time practically nothing w^as known about the true 

 plankton forms — ); the list of the localities for the coastal forms 

 fills namely perhaps a couple of pages, whilst the deep-water species 

 must be contented with some few lines. Though 25 years have 

 passed since then, the conditions have not essentially altered, although 

 there are naturally many new localities on the whole (and new 

 species). Further, as each new expedition brings home new species 

 belonging especially to the deep-water forms and the plankton or 

 increases our knowledge greatly with regard to the distribution of 

 Ihe already known species, we can see that, in spite of our appar- 

 ently very good knowledge of the Crustacean fauna of Greenland, 

 much is still w^anting before we can state the distribution of the
