232 AXTHOZOA HELIANTHOIDA. 



apertures : one sent forth his seminal filaments in company with the 

 limpid stream. The ground is literally covered with them. The 

 oral disc and tentacula present a variety of tints, — dark brown, — 

 light fawn, — dark and light ochre, — cream, &c. — all the tentacula 

 (one excepted) are annulated. I have fourteen individuals in my 

 experimental bottles, — each of them has the ochre-coloured or white 

 tentaculum (nearly one- third larger than any of the others) making 

 one of the central row ; and a white or buff mark or line extends 

 from it to the angle of the mouth on each side." 



The Actinia hellis of Professor Forbes in Ann. of Nat. Hist, v, p. 

 182, may prove to be a distinct species. " The body is cylindrical, of 

 a reddish or reddish-white colour, regularly and finely striated longi- 

 tudinally and transversely, and having glands of a bright yellow colour, 

 small and not very numerous, scattered over the surface. At the oral 

 end the body bulges, forming a calyx, on which the furrows are fewer 

 but more granulose. When the disc is expanded, this calyx laps 

 back, and is then almost even with the expanded tentacula. Disc 

 angular, in my specimens square, surrounded by three or four rows 

 of short tentacula, thickly set, of a white or brownish colour, 

 variegated, having generally a white line down the centre of each. 

 The disc is broad, brow^nish or orange, with white lines. The margin 

 of the mouth is bright orange. The animal can project its disc 

 forward in a pouting manner. Tentacula and disc are retractile. 

 The specimens described were about one inch long when expanded, 

 but I have seen larger." E. Forbes. — My accomplished friend per- 

 mits me to illustrate this description with figures copied from his 

 drawings. 



The Actinia hellis of Mr. Couch (Corn. Faun. iii. p. 76) is appa- 

 rently a variety of Act. coriacea ; and there can be no hesitation in 

 referring his Act. Tevipletonii to the true Act. bellis.

 marJced in the centre loith clavate radiating lands ; tentacula 

 numerous., irregular, the outer small and forming round the 

 margin a thicTc filamentous fringe. Ellis.
