510 Mr. Jeffreys's Supplejnejit 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.

Var. a alba. Neighbourhood of Salisbury ; and rejecta- 

 menta of the Thames at Battersea. 



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. Carfhusianella. 



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 lona. 



H. nitida,
