ledge than the fact." Tliey show what has been done, but faintly 

 shadow what remains to do. As the following table gives some 

 idea of the character of the ground on which these animals are 

 found in the greatest numbers, and the extent searched, I give 

 it in full, but in making any comparison it must be borne in 

 mind that all the long tracts of shore given, have not been searched, 

 but only in parts here and there, more or less fully. 



1st. The Shetland, including the Orkneys, and Scotland as far 

 as Kinnaird's Head, from which thirty species are recorded. 



2d. The North Sea, including the coast from Kinnaird's Head to 

 Spurn Head; fourteen s^Decies. 



3d. The Eastern, from the Humber to the Thames, a flat low 

 shore ; seven species. 



4th. The South-east, from the Foreland to St. Alban's Head, 

 chiefly chalk cliff's; nine species. 



5th. The Devonian, from St. Alban's to St. David's Head, a' 

 rugged rocky coast; fifty-one species. 



6th. The Irish Sea to the Mull of Cantyre, including Man and 

 the Irish shore; twenty species. 



7th. The Hebridean, from Cantyre to the Orkneys; six species. 



8th. The South Irish, from Carnsore point to Mizen Head; 

 seven species. , 



9th. The Atlantic, from Mizen Head to Rathlin Island; 

 twenty-one species. 



10th. The Channel Islands; twenty-two species. 



In all, seventy-five species; but as five of these are in some 

 degree doubtful, there remain seventy good species. 



It can easily be shown that some of these provinces or divisions 

 have only yielded fragments of what they contain. The Clyde 

 division, if included at all, comes under that of the Hebridean, 

 which only represents six species. If we thus make the Frith of 

 Clyde a sub-province of the Hebridean and give the Cumbraes as 

 a small point of it, the subjoined list shows for that portion alone 

 twenty-four species, and of these eight are new or not previously 

 recorded from Scotland, viz.: — Sagartia venusta; Sagartia nivea; 

 Sagartia imrasitica; Bunodes thallia; Peachia hastata; Peachia 

 triijhjlla; Edivardsia callimorpha; and Edwardsia carnea.
