a ring a little deeper than the general hue ; the region below the warts

marked with alternate lines of pellucid and opaque white.

North Sea : deep water. 
The acquisition of tlie magnificent animal above de- 
scribed, for which I am indebted to the kindness of Mr. 
D. Ferguson, of Coutham, not only enables me to augment 
tlie genus Bolocera, and at the same time the British Fauna, 
with another species, but also makes me better satisfied 
with the establishment of such a genus. Equal in dimen- 
sions to B. Tucclice, and presenting much in common with 
that species, there are peculiarities in this specimen wliich 
compel me to consider it specifically distinct. These are 
the brilliant hue of the column, its striate surface, the 
thinness of the integuments, the much feebler sulcation 
and constriction of the tentacles, and the rings of positive 
colour which adorn them, together with their power of 
complete retractation. All these characters make the pre- 
sent species a decidedly nearer approximation to Tealia. 
Indeed, when fully expanded, so remarkable is the resem- 
blance in form, size, and colour, to a fine T. crassicornis, that 
I have little doubt the reason of its having been liitherto 
overlooked, is that it has been passed over as that fiimiliar 
species. Yet tlie minute warts, the (really though slightly) 
constricted and furrowed tentacles, and the non-retractility 
of the margin, determine its place in this genus. 
The nobleness of its tout enscmhle, and especially the
