﻿THE COASTS OF RHODE ISLAND AND NEW JERSEY. 141 



Var. sahnonea. I found two specimens of an anemone of the same form as that of 

 Actinia marginata, about an inch in diameter, and of a bright salmon color, which I 

 suppose to be only a variety of the latter species. It was attached to large mytili, 

 appeared to be more active than the undoubted A. marginata, and when irritated 

 ejected jets of water from large pores of the body, a phenomenon I did not observe in 

 the more ordinary variety. 



The filiferous capsules of Actinia marginata are numerous in the tentaculae, but 

 especially so in the white cords of the interior of the body. (PI. X, figs. 17, 18). 

 They are elliptical in form, and measure about the .OG mm. in length by the .004 

 mm. in breadth; and they contain a spirally coiled thread and a style extending from 

 one pole about two-thirds through the centre. The ejected contents of the capsules 

 present two different forms. In the one case the style assumes the appearance of a 

 spindle-shaped tube, several times its original length, apparently having the extrud- 

 ed thread of the capsule coiled within it and having on its exterior long ciliary ap- 

 pendages, as represented in figure 21. In the other case the extruded style assumes 

 the appearance of a long narrow tube, apparently with the projected thread partly 

 coiled within it and partly everted from its distal extremity as represented in figures 

 19, 20. 



14. Actinia neglecta, Leidy. Body when closed, obpyriform, or shortly cylin- 

 drical ; when expanded, cylindrical, about an inch in length by one fourth of an inch 

 in breadth, smooth, translucent olive green. Mouth elliptical, with the lip composed 

 of six greenish white lobes. Tentacles numerous, up to half an inch in length, brighter 

 olive green than the body. A single specimen was found in the mud of a sound, in 

 the vicinity of Atlantic City. 



POLYZOA. 



15. Membranifora pilosa, Johnston. The stellate variety is very abundant at 

 Point Judith, encrusting the ruffled borders of Laminaria saccharina. It is also found 



' encrusting Chondrus crispus, the shells of Mytilus edulis, etc. In all the specimens I 

 observed, the cells possessed four lateral spines and a posterior spine, and this in no 

 case was developed to the dimensions which would give it the name of a bristle. 



16. Escharina lineata, Leidy ; fflustra Uneata, Lin. (PI. X. fig. 22.) Polypidom 

 crustaceous, circular. Polype cells oblong oval ; mouths large, with about ten inclined 

 spines on each side. Found by Mr. Ashmead, on pieces of anthracite coal from a 

 wreck, at Beesley's Point. 



17. Escharina pediostojia, Leidy; Lepralia periostoma, Hassal. (PI. X. fig. 2o.) 

 Polype cells, six-sided oval, closely punctured; mouth subtenninal, quadrate with 

 rounded angles, and slightly constricted at the sides. On shells. Beesley's Point. 

 Obtained by Mr. Ashmead.
