a subverticillate arrangement. The inside whorls are separated about 

 one-tenth of an inch. Polypes small, 12 or 14, in the median whorls 

 somewhat crowded. Tentacles slender, elongate, with slender, rather 

 distant lateral lobes along nearly their whole extent. 



" Length 1| inch, diameter in the middle rather more than one- 

 tenth of an inch." — VerrUl, 1. c.

" Polypi dom long and very slender, decorticated ; stem circular or 

 elliptical in section, smooth on the surface. Polypiferous lobes 

 slender, erect ; canals acute at the tips, and broad at the base, 

 arranged obliquely and alternately on the an tero -lateral faces of the 

 stem. These lobes occiipy the upper half of the polypidom, retain- 

 ing their full size to the extreme apex, but diminishing below, so 

 that on the middle of the stem they are exceedingly minute, and an 

 inch or two below are only represented by a slight ridge on the sheath, 

 in which arc 2 or 3 cells. The lower portion of the sheath is dilated 

 to about three times the thickness of the rest of the stem, 



" Length 19 inches ; diameter of the naked stem 0-03 inch, smallest 

 diameter of stem with the sheath 0-04 inch ; diameter of expanded 

 base 0-13 inch ; length of largest lobe Olo inch. 



" Known from T^ eJonf/atn, Gabb, by its more slender form, its 

 proportionally large polypiferous lobes, its cylindrical stem without 

 any grooves, and by the comparatively smaller portion of the stem 

 bearing the lobes." — Gabb, I. c.

" It consists of a thin, straight, fleshy stem, with alternate rows 

 of polypi on each side, and surrounding an elastic stony axis, varying 

 in length from 8 inches to 2 feet. The stem at one extremity is 

 truncate, but at the other is terminated by a vermiform fleshy 

 appendage. The stony axis, which gives strength to the stem, may 

 be traced at this extremity into a mere vessel filled with granular 

 matter. At low water hundreds of these zoophytes might be seen, 

 projecting like stubble, with the truncate end upwai'ds, a few inches 

 above the surface of the muddy sand. When touched or pulled they 

 suddenly drew themselves in with force, so as nearly or quite to
