frotacula, where they are frequently found, or into the sto- 
^ch. On many occasions, when forcibly pressing the A. 
.J^^wbryanthemum, several of the young have been forced 
hrougb the tentacula. The ova which are yellowish, arc 
c '°tlied with cilia, and become frequently developed into the 
P°lype internally. It would be out of place here, and tend to

H p e passed lightly over. The first and most common mode 
re production is by ova, the second by budding, as is ob- 
f ef ve ( ] only in the Zoanthus. In this genus the trailing lleshy

at intervals into papillary eminences, and afterwards becomes 
ev cloped into polypes.

lv ision. Having kept some specimens of A. dianlhus in 
■PbRnenient, it was found that they would occasionally

j. ‘be Hicquemare describes as the union of two individuals

are so gregarious as to be actually iu contact, and

Zoanthus Couchii is the only compound species of our 
? r es. It may be characterized as a number of small actinias

^"jted genus and tiil the discovery of a species on our shores 
^J°rt time since, had no representative in Europe.
