496 A. K Verrill — JVew American Actinians. 



umn was plain yellowish brown ; tentacles a lighter tint of the 

 same. Acrorhagi without differentiated pigment and hence 

 not conspicuous. The form of the body and tentacles were the 

 same as in the typical variety. 



This species closely resembles some of the varieties of the 

 common European species, but appears to differ especially in 

 the less numerous and larger acrorhagi, and in the fewer and 

 larger tentacles. Figures of this species will soon appear in 

 the Trans. Conn. Acad. Science.

Phymanthus (pars) Andres, Attinie Golfes Neapel, p. 285, 1884 (non Edw.). 



The generic name Epicystis was proposed for the Actinia 

 crucifera Les., A. ultramarina Les., and A. granulifera Les. r 

 the first being put in Sect. a. Therefore it is necessary to 

 take the former as the type of the genus, which is evidently 

 entirely distinct from the true Phymanthus.

This species is common in crevices and holes of the coral 

 reefs of Bermuda, where I collected specimens which were 6 to 

 8 inches in diameter of disk when fully expanded. It is a very 

 handsome species, when living.

 24-33, 1884 (development and structure). 



Column, in expansion, very long, slender, often flattened, 

 soft. In the oldest stages observed by me it was still without 

 external covering, but Prof. Mark figures it in one case with 

 a loose and imperfect coating. Tentacles, in the oldest para- 

 sitic stage seen by me, eight short, obtuse ; in a later stage 

 sixteen have been observed and figured by Prof. Mark. Mes- 

 senteries eight, in the largest specimens studied. 



Color of column whitish, flesh-color, or pale rose, translucent, 

 with eight longitudinal stripes of white or pale salmon-color. 



Length while parasitic, in extension, up to 1 inch or more 

 (20 to 30 mm ), diameter -5 to l'5 mm . 



The young, in various stages of growth, are frequently found 

 as parasites in the interior of a common ctenophorus jelly-fish 

 {Mnemiopsis Leidyi Ag.) on the southern coast of New Eng- 

 land. It is common at Wood's Holl, Mass., and Newport, R. I. 

 Several specimens of different ages are often found together.
