In youngest Fungias observed there is a stalk and vertical thecal walls ; 
6 septa are larger than the rest, and have others intercalated between 
them ; the walls then spread out, and a disc is formed, which separates 
from the stalk by absorption across a plane in the top of the latter. The 
detached top leads a separate existence. The top of the stalk develops 
enlarged septa and a new mouth, so that a new disc is formed, which 
separates in the same manner as the old one ; Lister. 
Larvae, supposed to be those of Feachia hastata, described ; 
H addon (1). 
A young Pennatula, 7 mm. in length, is described, consisting only of 
the axial or terminal polyp, which has eight seizing arms, and is con- 
tained in a cup with eight processes. There are five buds, four lateral, 
one median ; the last has no tentacles, and is on the surface usually, but 
erroneously, called ventral. The early stages of Pennatula and Benilla 
are compared; Jungersen. 
Development of the Hydroida ; Tikhomerov. 
Arachnactis is not the larval form of Edwardsia. Both this genus and 
Cerianthue are bilateral throughout life. The primordial Anthozoon was 
a free-swimming bilateral animal, provided with an invaginated buccal 
tube, held in position by septa, producing eggs, not buds, and developing 
continuously. The fixed condition is secondary, and characterised gene- 
rally by asexual reproduction ; Vogt (1). 
A number of specimens of Scyphistoma , though kept under observation 
for ten days, showed no sign of strobilization ; several explanations are 
suggested ; Fischer (2). 
The development of a species of Oceania is described, in which occur 
buds, which, like egg-embryos, recapitulate the larval stage through which 
the parent has already passed. In this case the continuity of the germ- 
layers is unbroken ; Brooks (1). 
The species in various families are classed under the headings, having 
the value of subfamilies, Actinulipares , Planuliparee , and Medusipares ; 
Du Plessis.

Two cases of fish which live for protection among the tentacles of 
Anemones : Sluiter. 
Ovula acicularis , living on Qorgonia flabellum ) resembles it closely in 
colour ; the same is the case with Pedicularia, which also lives on corals ;

GEOGRAPHICAL DISTRIBUTION. 
The characteristic features of the different coral regions are discussed ; 
the general distribution of certain important genera is given, and a list of 
widely spread forms is added ; Ortmann, pp. 182-188.
