kinds of Gramineae and Cyperaceae, which indicate a soil surcharged with 

 moisture, and in great need of drainage. Shelter and drainage, in my 

 opinion, constitute the basis of all permanent improvement which can 

 be effected on the lands of Erris. 



In summing up the foregoing remarks, I may state, first, that the 

 !■ iv valence of Erica carnea and Saxifraga umbrosa distinguish the Flora 

 of Erris from that of the east coasts of Ireland, as well as from any 

 other part of the British Islands ; which, taken in connexion with the 

 prevalence of Pinguicula lusitanica, Uypericwn elodes, and Anagallis te- 

 nella, affords further proof of its tendency to the Floras of western Spain 

 and France. 2nd. Respecting the theory I have noticed at the com- 

 mencement of this communication, the results of my late journey to the 

 west are such as to confirm it. Localities in England and Scotland, 

 with mountains of similar altitude and extent — having intervening glens, 

 lakes, and bogs, and particularly so large a sea-board — would certainly 

 produce a far more extensive and varied Flora than is to be found in 

 Erris, as would also be the case on the east coast of Ireland.

ON A NEW SPECIES OF PENTACBINITE FBOM THE OXFORD CLAY, WEYMOUTH, 



DOBSETSHIBE. 



This beautiful fossil crinoid was discovered by the Rev. Osmund Fisher 

 in the Oxford clay, Green Hill, "Weymouth, Dorsetshire, and presented 

 by him to the Dorchester County Museum. The late Professor Edward 

 Forbes since named it, in MS., after his friend the discoverer, and as it 

 had never been published, it has been intrusted to me for that purpose. 

 The following, therefore, is the description of the species : — 



Class.— ECHINODERMATA. 

 Order. — Cbinoidea. Genus, Pentacrinus (Mrlller). 



Pentacrinus Fisheri (Forbes). (Plate I., Fig. 1). 

 Sj). Char. — P. calyce parvo laevi ; articulis basalibus clypeiformibus, 

 quinque; articulis radialibus amplis quinque; articulis brachialibus 

 amplis, triangularibus, quinque; brachiis decern bifurcatis, articulis 

 cuneiformibus alternis ; pinnulis articulis octo ; columna pentagonal© ; 

 ramulis articulis contiguis.
