LUCERNARIAD.E. 
(?) POCILLOFORA INTERSTINCTA (Mliller). 
At a meeting of the Royal Society of Edinburgh (Trans. 
!March, 1846), Dr. Fleming exhibited a characteristic draw- 
ing of a Focilloj)ora presumed to be of this species, which 
was obtained by Dr. Hibbert in the Shetland Seas. Dr. 
Fleming had expected that a detailed description of tliis 
would have been published before the appearance of liis 
“ History of British Animals,” in 1828. It is, however, I 
believe, still a desideratum. 
The genus is marked by the following characters : 
Corallum massive or sub-trcc-like, with thick, imperforate 
walls. Visceral chambers divided by well-developed hori- 
zontal partitions, or floors, in successive stages. Plates 
rudimentary. Calices shallow, with a thick ring at the 
bottom of each, forming a sort of columella. 
LUCERNARIAD.E. 
Contrary to my original intention, I have determined to 
exclude this family from my work. Their true affinities 
arc with the Ilydrozoa and Meduscp.. The gelatinous tex- 
ture, the expanded umbrella, the ovaries in the substar.ee 
of the umbrella, the four-lipped mouth placed at the end of 
a free peduncle,* and the quadripartite arrangement, arc all 
!Medusan characters. The tentacles in marginal groups are 
found in Bouffainvilhva, and their form, — knobs at the tip 
of long footstalks, — agrees more with Slahheria than with 
Corynactis and Cay'yojdiylUa.
