Q74 Mollusca of Middlebury, Vt. and Vicinity, 
found it near Boston. {It is not rare here, and is associated with 
H. arborea; under logs, &c., both in moist and in dry lands. Dr. 
Gould has found it only near the water’s edge. 
This species is remarkable for its close resemblance above to 
H. indentata, Say, and beneath to H. arborea, Say. This te- 
semblance is so striking, that a view of either side alone would 
lead any one to place it with one or the other of these species. © 
A comparison of both sides easily distinguishes it.* 
H. multidentata, Binney. This beautiful little species was 
discovered by Dr. Binney several years since, in Strafford, Vt. 
Subsequently it has been found in this town very sparingly. It 
is remarkable for the roseate color of the animal, seen through 
the semi-transparent shell, and for the teeth. These are placed 
in rows, far within the aperture, on its outer and lower half. 
The rows are curved, with the convexity towards the aperture, 
and contain four to six closely approximate teeth, appearing 
through the shell like glass beads. The number of rows varies 
from two to four, of which never more than one is visible from 
the aperture. * 
H. minuscula, Binney. This species, recently discovered in 
Ohio, has also been found in this town. Under a log, in wet 
land, I found a large number, but have not found many ¢ 
where. It exactly resembles H. pulchella, Miill., in size and 
color, but that species is easily distinguished by its reflected lip, 
enlargement of the last whorl, and small umbilicus. 
ViITRINA. 
V. pellucida, Drap. This species was observed first on this 
continent by Say, who remarks that it “was first found neat 
Coldwater lake, in lat. 483° N., under stones, fallen timber, &e. 
It afterwards occurred, in similar situations, until we approa 
Lake Superior, when it was no more seen. No species of 
genus has been hitherto found in this country; this shell is there- 
fore the more interesting. The specimens which we collected 
do not appear to differ in any respect from those of Europe."t |

A description of this species, under the name of H. Janus, had been prepared 
for this article, when I received, through the kindness of Dr. Binney, ere 
der of his excellent monograph, printed in anticipation of the next No. of the Bost. 
Jour. Nat. Hist., in which, not aware that any one had discovered it prior rs 4 
Gould, he has quoted from Dr. G.’s MSS. The two following species re descr 
bed by Dr. B. in the same paper.
