374 Linnean Society. [April 3, 



The following British species are of doubtful position, viz. A. coc- 

 cinea, intestinalis , biserialis and vermicularis. The very curious A. 

 biserialis has a close parallel in Dana's Rhodora ; and these may 

 perhaps form together another genus when more is known about 

 them. A. intestinalis and Vermiculum show, in their slender 

 lengthened form, an approach to the free condition of Peachia, &c. 



Mr. Gosse next exhibits in a tabular manner one of the modes in 

 which the British non-coralligenous Actiniadce may be artificially 

 distributed ; and under the head of each genus comments on its 

 structure, limits, and affinities, concluding his paper with a diagram 

 intended to express, as nearly as such a representation can, the varied 

 consanguinities and cross- alliances of the group. 



The paper was illustrated by figures of Peachia hastata ; and by 

 magnified representations of the thread- cells and threads of several 

 species of Sagartia.

The following letters were read : — 



" 12 South Frederick Street, Glasgow, 

 "Dear Sib, 22nd March, 1855. 



" At Dr. Hooker's suggestion I send you, for the herbarium, two 



specimens of a rare British plant (^Hierochlo'e horealis), which, after 



having been erased from the list, was rediscovered near Thurso by 



Mr. Robert Dick, who states that it flowers so early in the year as 



May and the beginning of June, disappearing soon afterwards ; so 



that there was no wonder I and others could not find it in Don's 



station, Glen Kella, Angusshire, as botanists seldom go there before 



the end of July. 



" I am, dear Sir, yours truly, 



" R. Kippist, Esq." " Wm. Gourlie." 



The specimens forwarded with this letter were marked as gathered 

 by Mr. Robert Dick, at "Thurso, Caithness, May 1854."
