tudinal furrows, as in some other species of that genus. There are 16 
tentacles alternately long and short. 3 principal varieties, cornea^ ornata, 
and simplex^ are recognized.

Contains a description of the histology of Anemonia sulcata and 
Actinia equina. There is a deep fibrillated layer beneath the ectoderm, 
from which may be separated granular, nucleated, “ epithelio-muscular ” 
cells, provided with a singly or doubly pointed basal fibril. In the 
tentacles they are much more distinct, club-shaped, and connected with 
the fibril, which is hero very short, by a peduncle. The author regards 
them as having botli epithelial and sensory functions, and as sometimes 
giving rise to muscular fibres. The longitudinal muscles of the tentacles 
are composed of extremely long fibres, which, owing to the fact that 
they possess numerous nucleated prominences on one side, must be looked 
upon as compound, and as such are termed “ pluricellular.” The meso- 
derm has firm walls, and in section resembles hyaline cartilage. There is 
also an account of the development of some species. Lacaze-Duthiers’s 
conclusions as to the development of the mesenteries are confirmed. The 
so-called mesoderm is developed frorti the ectoderm. In Actinia equina^ 
the gastrula is formed by invagination, and the alimentary canal by a 
kind of secondary invagination, the edges of the gastrula mouth being 
turned inwards and downwards into the cavity, which becomes filled by 
large vitelline masses.

Contains an account of the different kinds of gemmation occurring in 
corals. In Madrepora, increase takes place by what the author terms a 
patriarchal growth. In other forms, simple division occurs. The growth 
is, as in a tree, though not perpetual, unlimited.
