Plate IV. Figs. 7, 7 a. 



The main stem is upright, without polyps, giving off cylindrical branches 

 along the sides; from these, small lateral branchlets arise all along the sides as 

 well as at the ends, each bearing a cluster of three to live, or more, prominent 

 polyp-calicles, which are larger than in A. carnenm, and, when contracted, are 

 obovate, incurved, and show the bases of the eight tentacles as small terminal 

 lobes. The surface or outer layer of the polyp-bodies and bases of the tenta- 

 cles is filled and covered with spicula, so as to render them decidedly rough, 

 rigid, and incapable of complete contraction. The calicles are more or less 

 distinctly eight-ribbed; the stouter spicula project slightly in rough points 

 along the ribs, while those in the intervals, which are more slender, fusiform 

 and warted, are imbedded in the integument. 



The coenenchyma is rather firm and stiff, due to the abundance of the spicula. 



The larger spicula (Fig. 7 a, I) are rather large, long, stout, mostly club- 

 shaped in f(jrin, with the smaller end thickly covered with small warts, and 

 the large end covered with large, roughly lacerate warts, sometimes taking the 

 form of ragged spinules, in other cases having the form of lacerate* flattened 

 lobes; with these are some roughly warted fusiform spicula, of similar size 

 (Fig. 7 a, c), and uumerous smaller rough spicula, some of which are fusiform 

 (Fig. 7 a, d) and others club-shaped, some of them slender and others stout. 



Height, in alcohol, 60 to 80 mm. or more (about 3 inches) ; breadth, 35 to 

 50 mm.; diameter of contracted calicles, 1 to 1.25 mm. 



One small specimen was dredged by the Blake, at Station 339, in 1186 

 fathoms, off Delaware Bay. Several examples were dredged in 1877, oft' Hal- 

 ifax, N. S., in 52 fathoms, by the U. S. Fish Commission. Several good
