ISTORY.—Hygromia hispida (hispida, 
hairy) was first noticed by our famous 
countryman Dr. Martin Lister, if his Cochlea 
subfusca claviculad modicé producta be really 
this species, as surmised by Morton in 1712; 
but the publication by Petiver is, however, 
the generally accepted record of its first 
discovery in this country. 
It is the Helix hispida of Linné, and the 
type specimen existed in the Linnean 
Collection, and may still be in existence, 
and have escaped the search made for it by 
Mr. Roebuck and myself when we examined 
and isolated all the British land and fresh- 
water shells in the Linnean cabinets. 
ZZ 
a a Mr. Hanley recorded its presence in the 
Linnean collection, and I saw it there when I 
looked over the specimens about thirty years ago. As stated by Mr. Hanley 
it was clearly the somewhat flat, widely umbilicated form described as 
Helix concinna by Dr. Gwyn Jeffreys. 
The present species is dedicated with profound respect to the late Dr. 
Carl Agardh Westerlund, the distinguished conchologist, of Ronneby, 
Sweden, who has rendered such immense services to the investigation of 
the Palearctic terrestrial mollusca. 
There has been considerable divergence of opinion amongst conchologists 
in reference to the group of species or varieties clustering around /7. hispida. 
The H. hispida of Moquin-'l'andon must be a different species to our own 
if his description of the reproductive organs is to be relied upon, as he 
describes his species as possessing only one dart-sac, whereas our species 
is always provided with two, each furnished with a love-dart, and also an 
accessory superimposed glandular sac; while Dr. Paetel regarded the
