R. J. L. GUPPY LAND- SHELLS.

(Journ. Conch. 1867, p. 256), on account of my having stated 
that the teeth of Conulus vacans were like those of Testacellus. 
My remark, however, only referred to the lateral teeth ; for 
those of the median portion of the odontophore are not like 
the teeth of Testacellus. In 1870, Prof. Ralph Tate re- 
described the genus Guppy a (Amer. Journ. Conch., vol. v., 
p. 154), and I apprehend that that name, in default of a 
better, must stand for the group of which C. vacans is a 
member, and of which Guppya selenkai may be regarded as 
the type. The name Stenopus was adopted by Woodward 
in his Manual to replace Nanina and Ariuphanta ; but it is 
almost superfluous to say that this very doubtful improve- 
ment in nomenclature was not accepted by naturalists. 
I collected a single example of a mollusk, which I take to 
be the Stenopus cruentatus of Guilding ; but I cannot regard 
it as congeneric with Guppya livida. I was unable to extract 
the animal without injury to the shell ; and having only one 
specimen, I was unwilling to sacrifice it. It appears to me 
that it is a Zonites, or perhaps even a Macrocyclis. The foot 
was singularly long and narrow, and of a deep yellow. 
Bulimulus stramineus is nearly akin to B. vincentinus ; the 
former is broader in its proportions, with more rapidly 
increasing whorls, and of a delicate transparent golden yellow, 
like the typical form of B. aureolas. I have some suspicion 
that B. vincentinus is not confined to Trinidad, as lately sup- 
posed, but is also found in S. Vincent. 
I did not find Amphibulima tigrina (Lesueur), which is 
stated to be a native of S. Vincent. Judging from its 
similarity to Amph. pardalina of Dominica, which lives em- 
bedded in the thick moss on the trunks of tre^s on the 
highest mountains, I had expected to have found A. tigrina
