Mr. H. J. Carter considers the Ammothea which occurred 

 abundantly in Barents Sea, and of which Mr. Grant brought 

 me many specimens, distinct from A. Luetheni of Maren- 

 zeller. He has drawn up the following description : — 



Ammothea glomerata. 



Cauliflower-like, consisting of more or less verruciform 

 polyps aggregated into tuberose, globular masses, arising from 

 a longitudinally corrugated stem. Colour, in spirits, white. 

 Texture cartilaginous. Surface irregular, on account of the 

 variety in size and variable amount of projection of the 

 polyps. Composed of subcartilaginous material charged with 

 calcareous spicules. Polyps octotentacular, the largest about 

 l-24th inch in diameter ; tentacles tubular, coated both inside
