siderably protruded from the cell, below the diver- 

 gence of the tentacles. The great circular aperture 

 on the upper surface, appears to have a rim. (See 

 fig. 4). 



June \%th. A week old : no material alteration 

 from last record. I found, however, the next day a 

 gemmule represented at fig. 5, which perfects the series. 

 It was in a state intermediate between figs. 1 and 2. 

 Its length is ;^th inch. The edges are pellucid, and 

 have an appearance of radiating fibres. The redness 

 is curdled, but not wholly separated. This continued 

 for several days, the red mass slowly concentrating •

 broken accidentally ; granular matter came out, leav- 

 ing a glassy cell attached to the side of the vessel. 

 The species was probably Lepralia coccinea ; but 

 eight spines are more than are ascribed to any of 

 our species.

June 18. — In the glass jar that contains Actinige, 

 &c., that I brought from Torquay, I found on the 

 Membranipora, a very young specimen of Volycera 

 A.-lineata, about \ inch long : very pretty. Some of 

 the cells of the polype appeared to have been recently 

 gnawed, probably by this little mollusk. 



In the same vessel I found another species of 

 Coryne. (Plate XIY, figs. 4 — 6). It is sessile on a 

 decaying frond of some Alga, about g^inch in height 

 in medium extension, with no appearance of tube. 

 The polype is sub -cylindrical, slightly clavate, round-
