margins, eight or nine in a series, large, ovate, muricate, 

 affixed by a narrow base, the three hinder pairs small : foot 

 with plain margins : veil above the mouth enlarged, truncate, 

 entire : tentacula dorsal, simple, long, filiform, exserted from 

 a wide trumpet-shaped sheath uneven on the margin ; imme- 

 diately in front of them there are two very short processes or 

 tentacula, without any sheath, and there is a small prominent 

 orifice on one side between the first pair of branchiae : a few 

 minute tubercles are scattered over the back. 



The remarkable branchiae of this species, which Montagu 

 has aptly compared to a pine tree in miniature, point it out as 

 the type of a new genus, which the structure of the tentacula 

 confirms.

 interesting kind of matter, the laws, list of members, &c. 

 For the public there are eighty-two pages, and seven copper- 

 plates filled with figures, some of them coloured, for the book's 

 price. The titles of the subjects treated of are as follows : —
