Report on the Echinoderms of North-East Greenland.

traceable in the composition of the littoral fauna. The littoral fauna 

 may be expected to be in the main purely arctic along the coast of 

 Greenland, but below 200 m we may expect to find the Atlantic 

 boreal fauna represented along the Southern Coast, from Angmag- 

 salik to Holstensborg, or upon the whole as far as the influence of 

 the warm Atlantic water makes itself sufficiently felt for making the 

 conditions suitable to the boreal forms. This is exactly what occurs 

 in regard to the Echinoderm fauna, as I shall try to show. 



The total number of Echinoderms, littoral and deep-sea forms, 

 known from Greenland is 72. In this number are included also 

 those met with in the deeper parts of the Davis Strait and of the 

 deep sea oft" the East Coast. The list of Echinoderms known from 

 the Greenland seas is as follows:^

The species marked * have onh^ been recorded from the sea between Jan Mayen 

 and East Greenland. The Swedish Zoological Polar Expedition 1900. (Öster- 

 gren. Zool. Anzeiger. 1901. Nr. 642. p. 252). The species marked" have not 

 hitherto been recorded from Greenland but there are specimens from there in 

 the Copenhagen Museum (partly from the "Tjalfe" Expedition), about which I 

 shall give information later on, in the reports of the "Ingolf Expedition.
