78 MARCH. 



There are multitudes too of a charming little kind, 

 which, on account of the pure whiteness of the crown 

 of tentacles, is known as the Snowy. 1 The disk is of 

 the same spotless hue ; and the column of a light drab 

 deepening into pale olive towards the summit. "With 

 the exception of its colours, this species has a very 

 close resemblance to the Rosy, with which it is gener- 

 ally associated, even as we see it here. And here is the 

 Orange- disk, 2 one of exceeding loveliness, which you 

 might fancy a cross-breed between the Rosy and the 

 Snowy, having the rich brown column of the former, and 

 the white tentacles of the latter; but that it has a 

 character of its own in the disk being of the most 

 brilliant orange-red. ALL these are scattered in the 

 most abundant profusion, looking like gems sown on 

 the rough rock; or, as I compared them before, like 

 gorgeous composite flowers, of which you might easily 

 fancy the little tufts of green and purple Algae, to be 

 the proper leaves. There are also others, less con- 

 spicuous, the Daisy, the Sandalled, the Cave-dweller, 

 the Translucent, 3 more or less numerously mingled with 

 the rest, of which I have not space here to speak, but 



1 Sagartia nivea ; two of this species, one closed, the other partially 

 opened, are seen at the left corner of the foreground in Plate vn. 



4 Sagartia venusta, a group of which occupies the right-hand side of 

 Plate ix., including both expanded and closed individuals. 



8 Sag. bellis, sphyrodeta, troglodytes, pura.
