SAGARTIAD^. 
To Mr. W. P. Cocks, of Falmouth, to whose scientific 
research our zoology is largely indebted, Dr. Johnston 
owed the admission of this species into his “ History of 
British Zoophytes.” I am under obligations to the kind- 
ness of the same gentleman, who has favoured me with 
some additional notes on the species, and a beautiful 
coloured sketch, which I have copied in Plate VI. 
The generic position of this beautiful form I indicate not 
without doubt. The short conical tentacles, crossed with 
bars, suggest a relationship with Tealia / and this affinity 
had occurred to its diseoverer, who in one of his MS. notes 
has added the words, — “ allied to crassicornisy On the 
other hand, the marginal line around the base, and the 
gonidial tubereles being distinguished by a different colour 
from the rest of the animal, while agreeing inter se, suggest 
Actinia, of whieh these peculiarities are characteristic. 
There is, too, a well-known variety of A. mesemhryan- 
thenium, whieh is green, marked with lines of yellow dots, 
and of this circumstance I ventured to remind Mr. Cocks. 
Ilis reply was as follows : “ In the A. mesemhr. var. the 
stripes and spots are as in cJirysosplenium, but several 
shades lighter, and the labial tubercles, as well as the 
edging of the base, are bright blue ; the tentacles arc 
uniformly of one colour, and are much more numerous, 
slender, and tapering.” 
The character of the surface, however, decidedly separates 
it from both the Actiniadoe and Bunodidee. ]\Iy friend had at 
first written, — “ Suctoreals numerous, scattered, embedded ;” 
but he afterwards added the following particulars : — “ When 
I examined the body of the cJirysosplenium with a lens of 
two inches’ focus, the surface appeared to be pierced or 
punctured, and in appearanee resembled a piece of smooth 
India-rubber when pierced with a pin ; not the slightest 
trace of tubercles apparent. Tlic body when contracted
