510 Mr. Jurrreys’s Supplement to the “Synopsis of 
H. concinna, p. 336. 
H. depilata. | Pfeiffer, i. 35. t. ii. f. 18? 
By a careful examination of many hundred specimens from 
different localities, I am inclined to think that the above-named 
species must be eventually referred to the H. hispida. It is the 
H. rufescens of Swiss authors. The variety a abounds in the 
environs of Dover and the opposite coast of Calais. 
The H. plebeium of Draparnaud is sometimes found in com- 
pany with this species, and is probably another of the numerous 
varieties of the H. hispida. 
H. rufescens, p. 337. 
Var. « alba. Neighbourhood of Salisbury ; and rejecta- 
menta of the Thames at Dattersea. 
H. hispida, p. 338. 
The H. conspurcata of Draparnaud is different from this spe- 
cies, being allied to our H. caperata. 
Dr. James Lindsay, in a letter addressed to Roderick Impey 
Murchison, Esq., F.R.S., and lately read before the Society, 
states his having found the H. obvoluta alive and in consider- 
able plenty in Ditcham Wood near Buriton, Hants. Mr. G. B. 
Sowerby had previously favoured me with a specimen from the 
same place. But its confined locality and the circumstance of 
its having remained so long unnoticed by British authors might 
warrant a suspicion that it may be of the same recent and preca- 
rious indigenousness in this country with the H. Carthusianella. 
H. ericetorum, p. 338. 
I am quite satisfied of this being the H. cespitum of Drapar- 
naud. 
. A more produced variety was obligingly favoured me by the 
Rev. R. T. Lowe, who tells me he found it many years ago in 
great abundance at Iona. 
H. nitida,
