Hyalinia nitidula (Drap.). 
Nomenclature.—The correctness of the application of the name 
nitidula to the present species has recently been challenged by several 
writers, some of whom believe that Hyalinia pura, which Draparnaud’s 
figure in their opinion more resembles, was intended to be indicated. 
his opinion they consider is strengthened by his inclusion of Hyalinia 
radiatula as a variety; but it must be remembered that Draparnaud 
expressly described the variety as much smaller, and figured it as such. 
An examination of Draparnaud’s original description and figures will allay 
any doubts that may exist in this respect. 
For the convenience of those not able to conveniently consult Drapar- 
naud’s work, the original diagnosis given on p. 68 is now supplemented by 
the original description and a copy of his figure, the latter by some error 
of the author or printer being attributed therein to Helix erystullina. 
Original Description.—H[elix)]. nitidula.—ANIMAL pearly-grey, with black and 
white specklings.
