Verm. ii. 46. Penn. Brit. Zool. iv. 137* Mont. Test. Brit. 411. — 
Shady places, common. 
Breadth about an inch ; whorls five, wrinkled across. Colour yellowish, 
without bands, with a single band, or with several bands. These varieties 
are considered by the Reverend Bevitt Sheppard as distinct species, because 
they do not unite indiscriminately in the season of love ; and he adds, “ from 
the one-handed and many-banded sorts I have taken the spicula or love-darts ; 
that of the former is four-sided in the middle, and perfectly straight ; in the 
latter it is also four-sided in the middle, but curved as in H. aspersa." 
78. H. hortensis. — Margin of the mouth invariably white ; 
even near the pillar. 
Cochlea citrina. No. 1. List An. Ang. 117.— H. hort. Mull. Verm. 52. 
Mont. Test. Brit. 412. — Not common. 
This species closely resembles the preceding, of which it is considered by 
many as only a variety. It is smaller in size, and less common. 
79. l^.fitsca. — Shell tliin, pellucid, horn- coloured, with five 
or six whorls. 
Mont. Test. Brit. 424. t. xiii. f. 1. — In England and Ireland, not uncom- 
mon. 
Breadth less than half an inch ; smooth ; mouth lunated, narrow near the 
pillar, thin, not reflected ; whorls rounded, the last large. This seems to be 
the H.fulva of Muller, No. 249 — A variety of a white colour, glossy, and 
pellucid, was sent to Montagu from Scotland by Mr Boyes.
