specimen, however, the calcareous bodies do not form a coherent net- 

 work ; most of them he quite isolated upon the disc, and only towards the 

 edge of the disc begin to be sufficiently numerous and coherent to justify 

 the appellation of network. The inter-radial dermoskeleton (PI. 1, fig. 5) 

 consists, just as in the North Atlantic specimens, of tesselated irregular, 

 polygonal, calcareous plates. In the Havne Fjord specimen, however, 

 the plates are farther apart, thus making comparatively larger inter- 

 stices in that specimen's skeleton. In the Havne Fjord specimen, more- 

 over, the interstices between the marginal plates are larger. A more 

 detailed description of the skeleton of the North Atlantic Solaster 

 furcifer will be given in a work on the starfishes collected by the 

 "Michael Sars" (Grieg, 16, p. 69).

There is only one specimen from each of these localities, their arm- 

 radius being respectively 15 and 22 mm., disc-radius 8 and 14 mm., the 

 breadth of their arms at the base 8 mm. and 12 mm., the proportion 

 of the disc-radius to the arm-radius being thus 1 : 1.88 and 1 : 1.57,
