hue exists alone, by a separation of its constituent elements, blue and 
yellow. We may distinguish the following varieties : — 
o. Hepatica. The liver-brown condition above described, which is the 
most common (fig. 2). 
* Approaching the red. 
j8. R uhra. Column dark crimson ; disk and tentacles as before. In 
youth this and the following variety are of a pellucid light crimson 
(fig. 5). 
y. Chiococca, Column rich scarlet ; basal line flesh-colour or non- 
apparent ; disk and tentacles full crimson ; spherules pure white (fig. 7, 
labelled A. chiococca). The A. Forshdlli of the Red Sea, the A. cerasum 
of the Scottish Coast, the A. chiococca of St. Ives and other parts of Corn- 
wall, must be considered as belonging to this variety ; nor can I separate 
from it the A. tabeUa of the Cape Verd Isles, except that this approaches 
the var. 
** Approaching the green. 
5. UmhAna. Column, disk, and tentacles, a yellowish umber-brown ; 
spherules (as in all the following) azure; basal line (as in all of this 
section) blue (fig. 3). 
€. Ochracea. Column, disk, and tentacles orange-bufiF. 
f. Olivacea. Dark olive. 
t]. Glauca. Pellucid bluish green ; tentacles pale greenish blue (fig. 1). 
0. Prasina. Fine leek-green ; tentacles the same, pellucid. 
*** Colours interrupted. 
/. Opora. Leek-green, with longitudinal broken lines of light green or 
pure yellow ; spherules and basal line blue (fig. 4). 
K. Tignna. Red, streaked with yellow (Tugwell). 
Fragacea, Liver-coloured, or dark red, studded with numerous spots 
of light green ; no basal line. Attains a very large size (fig. 6). 
The most marked of the above varieties is undoubtedly 
the last, — the Strawberry, as it is familiarly named. Its 
constancy of colour and pattern, its tendency to an ovate 
form, and its great size, distinguish it from its fellows ; 
and yet I cannot, after much consideration of the subject, 
in the presence of the animals themselves, convince myself 
that it is entitled to specific distinction. I have found 
specimens in which the spots were small and crow'dcd, 
others in which they were large and scattered, others in 
which they were small and scattered ; sometimes the 
spots are portions of lines irregularly interrupted, and not 
seldom considerable regions of the surtacc are quite des-
