а list of species in alphabetical order, any information desired will be 

 easily found. 



Only in connection with those species which have not previously 

 been recorded from Greenland, or where other circumstances make it 

 desirable, will any references to literature be made. New, or in other 

 ways interesting, species are marked with x .

X Brachyurid-larva (Hyas coarctattis Leach?). 



Between St. 2 and the mouth of the fjord a few specimens of the 

 SQime Brachyurid larva which I have described in the report of theTjalfe 

 Expedition (Vid. Meddel. Naturh. Foren., Kbhvn., vol. 64, 1912 (1913), 

 p. 127, fig. 33) were taken in the surface Plankton. In the place above 

 cited I mention that it greatly resembles the larva of Hyas araneus, 

 from which it differs, however, in some respects. Now, we have here 

 before us the interesting case, that of the three crabs which are found in 

 Greenland {Chionoecetes opilio, Hyas araneus and H. coarctatus). Dr. Nord- 

 mann's collections only contain specimens of the one species, Hyas 

 coarctatus, and as both the other species are larger forms, it is inconceiv- 

 able that they should not have been included in his material if they 

 really occur in the fjord. True, the larva was found at the mouth of 

 the fjord, so that it is possible that the specimens originated from adult 

 crabs from Baffin Bay; but yet I think, on account of the close resem- 

 blance to the larva of Hyas araneus, that there is little doubt that the 

 larva in question is that of Hyas coarctatus.
