or A. Marginata, but quite distinct. The largest specimens 

 obtained were an inch, in diameter. Specimens of this size have 

 about 150 tentacles, conical, transversely striated, and uniform in 

 size, placed at the margin of the disc in about three rows. The 

 disc rises when expanded considerably above the plane of the ten- 

 tacles. The body below the tentacles is short, and expands to- 

 ward the base. When contracted the form is blunt conical, with 

 a, smooth outer shin, apparently destitute of tubercles and pores.

The colour, when contracted, is a fine reddish salmon, arranged 

 in vertical stripes on a light ground. When expanded the lip 

 and oral bands are reddish ; the tentacles are salmon colour, 

 deeper toward the tips. The disc between the tentacles and the 

 oral bands is dull purple, with two rows of pure white spots This 

 beautiful species is comparatively locomotive and active ; and 

 when placed in a basin, removed from its stone, and crept around 

 in search of a more convenient situation. 



I think it very probable that Stirapson's A. Carneola is the 

 young of this species; but my specimens do not include any so 

 small as that which he figures, and the colour and tentacles differ. 

 If distinct from A. Carneola it is probably new. Its description 

 is as follows: — 



Body short, cylindrical, smooth ; colour red, arranged in 6tripes ; 

 tentacles triserial, short, conical, striated, reddish ; disk promi-
