enables me to contribute something to a settlement of some 
doubtful points respecting one or two of the terrestrial 
molluska of that island. Unfortunately my state of health 
prevented me from doing as much as I had wished ; and the 
excessive heat of the weather (from 92° to 94° in the shade 
every day) rendered active exertion difficult. 
I append a list of the land-shells of S. Vincent, in which 
are distinguished those named in Bland’s list (Ann. Lyc. 
Nat. Hist., New York, vol. vii., 1861) and those which I 
have found, but which are not recorded in his list. I proceed 
to remark on such of the species as appear to deserve par- 
ticular notice. 
Land-shells are much scarcer in S. Vincent than in Grenada 
and Dominica and other islands of the Antilles. Nevertheless 
the mountains seemed exceedingly favorable for the develop- 
ment of mollusks, yet they were rare ; and I attribute this 
fact to the action of birds. I met with many dead shells, 
the contents of which had evidently been extracted by birds. 
Of Guppya livida I only found a few specimens ; these 
were in different stages of growth, and enabled me to ascer- 
tain the fact that my Conulus vacant found in Trinidad is the 
same species, and that therefore the name given by me must 
be abandoned in favor of Guilding’s. 
This, it appears to me, is a suitable occasion to make 
an observation on the use of the name Stenopus , applied by 
. / $ 2. 2 
Guilding^ to two species of land-shells found by him in 
S. Vincent. The name Stenopus was originally given by 
Latreille ^fo 1 a crustacean, it is therefore inapplicable to a 
mollusk. I noticed this fact when describing my Conulus 
vacans in Ann. and Mag. Nat. Hist. 1866, 3 ser. , vol. xvii. , 
p 53 ; upon which Morch proposed the name Guppj r a
