206 A. E. Verrill — New Actinians. 



smooth wall, much thickened at the submarginal fold. There 

 are 16 to 24 pairs of perfect mesenteries, the number being 

 variable ; their longitudinal muscles are thin and diffuse. The 

 perfect and part of the imperfect mesenteries are gonophoric, 

 in the type. Tentacles are numerous and rather stout.

Column and base very versatile in form ; the base may be 

 broadly expanded or much contracted ; and when detached may 

 become small and puckered or swollen and conical. Column 

 may be cylindrical, or almost hour-glass-shaped, or bottle- 

 shaped, these changes taking place very rapidly. The wall is 

 smooth in expansion, more or less wrinkled when contracted ; 

 there are neither verrucse nor suckers ; a distinct thickened 

 marginal fold or collar may be formed in contraction. Tentacles 

 rather long, tapered, moderately stout, versatile, often per- 

 forated, banded ; 96 or more in the larger specimens, in two 

 or three crowded marginal rows, the outer ones distinctly 

 shorter and smaller. Disk very changeable, convex or concave. 

 Mouth often raised ; siphonoglyphs two ; lips with numerous 

 (about 14) small folds on each side. 



Color variable, usually bright and translucent ; column gen- 

 erally pale pink or flesh-color, irregularly splashed and mottled 

 with rose red, carmine, or scarlet, except just below the mar- 

 gin, where there is usually a zone without spots ; sometimes 

 the whole surface is plain flesh-color, or pale greenish white. 

 Tentacles usually pale pink or flesh-color with three bands of 

 rose-red or carmine, of which the distal occupies the tip ; from 

 the proximal band a narrow line of red usually runs along each 

 side of the base to the outer part of the disk, where it may 

 form a short radial line ; but these are often interrupted, so as 

 to form a circle of red spots on the disk ; another circle of 

 small red spots usually occurs near the mouth. There is 

 usually a flake-white spot at the inner base of each tentacle. 



was not originally referred to the genus by Edw. and Haime. The same is true 

 of P. Peruviana (Less.), adopted as type by Andres. 



AUoadis, new genus. Type A. excavata (Hert.). Paractidas with the circular 

 muscles of the tentacles unequally developed at the base, it being much thick- 

 ened on the inside. Wall sulcated. No mesenterial stomata. 



A. excavata was taken in 1375 fathoms by the Challenger.
