JAMES A. GRIEG. [2nd ARC. EXP. FRAM 



Like the arctic form of the Solaster papposus^ of the North At- 

 lantic, the older, fully-developed specimens from Jones Sound have 

 numerous inter-radial paxillee. The 'number of these, however, as the 

 table shows, is subject to individual variations. 



The abactinal skeleton (PI. 1, fig. 1) consists of a network of tiny 

 calcareous plates. This network is not so wide-meshed, however, as that 

 in some specimens from Spitzbergen that I have had for comparison. In 

 the specimens from Jones Sound also, there are more solitary calcareous 

 bodies in the meshes than in the Spitzbergen specimens. There are 

 one or more papulae in the meshes, according to the size of the latter. 

 In the larger meshes in a specimen from Havne Fjord, 71 mm. in 

 diameter, there are as many as 7 papulae. In other respects, the abactinal 

 skeleton is subject to variations, and specimens are to be found in 

 which it recalls the Solaster papposus living on the west coast of 

 Norway. This resemblance was most marked in two large eleven-armed 

 specimens from the mouth of Stor Valley, in which the abactinal skeleton 

 was wider-meshed and more robust than in the other specimens from 

 Jones Sound. In these two specimens, also, the abactinal paxillse dif- 

 fered from those in the others. The paxillse in the latter recall those 

 in specimens from the arctic regions of the North Atlantic, whereas in 

 the Stor Valley specimens they bear a greater resemblance to those 

 found in specimens from the west coast of Norway.

There is only one specimen from each of these localities. Their

 the Norwegian Sea.
