29^ "The Irish Naturalist. [Nov., 



Donegral Plants.— In ih^ /otimal of Botany for September, Mr. H. C 

 Hart records Cusaita Epithytjmm, Galium J\Tollugo, and Reseda suffruticulosa 

 from the vicinity of Rosapenna Hotel, and Cochlearia granlandica from 

 several headlands of north-west RossguU. 



Medlcagro sylvestrls In Scotland.— With reference to my paper 

 in last number on the occurrence of this plant in Ireland, it is worth 

 giving prominence to the fact that at a meeting of the Natural History 

 Society of Glasgow, held on Sept. 30, specimens of M. sylvestris from Heads 

 of Ayr, Maybole parish, were exhibited on behalf of Mr. Andrew Gil- 

 christ and Rev. D. Landsborough, who found the plant growing there 

 abundantly in August last. I have to thank Mr. A. Somerville, B.SC, for 

 a copy of a local paper containing a report of the meeting.

Matricaria dlscoldea DC. at Howth.— This curious rayless 

 Matricaria^ whose occurrence in several stations in Co. Dublin has lately 

 been recorded by Mr. Colgan (/. A^., III., 215, 1894), has now made its 

 appearance at Howth, where I observed it on Sept. 18 growing on waste 

 ground by the new road between the police station and the chapel. M, 

 discoidea has not yet been observed in any other Irish county : it is a 

 native of North America, now naturalized in several countries of Northern 

 Europe, though as yet very rare in Britain.

ZOOLOGY. 



HYDROZOA. 



British Hydrolds and IVIcdusae.— Readers of Mr. E. T. 

 Browne's list of the Medusas ofValentia harbour in the July number 

 oi 'C^Q. Irish Naturalist will turn with interest to his paper "On British 

 Hydroids and Medusae "in Proc. Zool. Soc. Land. (pp. 459-500, pis. xvi,, 

 xvii.), in which several of the Irish forms are described in detail and 

 figured. 



CRUSTACEA. 



Frcc-swlmmlng Copepoda from the West Coast of Ire- 

 land. — Under this title, Mr. J. C. Thompson contributes to the Trans. 

 Biol. Soc. Liverpool (vol. x,, pp. 92-102) an account of the copepods 

 collected at Valentia Island by Mr. E. T. Browne by tow-netting. 

 Twenty-two species are recorded, of which the most noteworthy are 

 Metridia armata, Candacc pecdnata, Pscudocalamcs arviatiis, Monstrilla rigida, 

 Corycdus speciosus, and Oncixa mediterranea. The two last are of special 

 interest as distinctly southern forms. The Oncaa has occurred at Ply- 

 mouth, but the Coryacus appear new to British waters. Mr. Thompson 

 also gives a list of the copepods taken on the west coast of Ireland by 

 Prof. Herdman in the " Argo " in 1890.
