Valparaiso, Chili. Exp. Exp. 



In one variety, the body, with the disk and tentacles, is of a deep 

 rich green colour ; the centre of the disk a little paler, the marginal 

 tubercles a bright yellow, and the under part of the foot yellow. In 

 another, the body is a deep crimson, with the tubercles of the lateral 

 surface deep green, and the marginal tubercles vermilion ; the ten- 

 tacles dark lake, and the central part of the disk, a paler lake ; under 

 surface of the base, a bright orange, approaching to vermilion. The 

 disk is very broadly dilated, and forms four or five lobes or folds, by 

 an upturning of the margin. J. DRAYTON.

The disk of this species is usually in five folds, and the tentacles 

 cover a breadth of half to three-fourths of an inch. The surface of 

 the disk, between the tentacles and the mouth, is strongly marked by 

 numerous radiating lines. One variety has a royal smalt colour, with 

 the small papillae of the surface a fine ultramarine, the disk a paler 

 blue, and the marginal tubercles pearly white. Another is verdigris 

 green, with the papillae of the same colour, and the marginal tubercles 

 yellow. Another (fig. 8), apparently the same species, though a little 

 higher (near 3 inches), has the papillae of the lateral surface of a sap-
