Shell broadly umbilicated ; orbicularly-depressed ; solid ; lightly decussated 
by incremental striae, and numerous fine spiral lines: color black or reddish 
brown, under the epidermis white and shining ; suture deeply impressed; spire 
depressed ; whorls 6, regularly increasing, the upper ones flattened, the last 
(jonvex, rounded below, and slightly deflected at the aperture; umbilicus broad, 
showing all the volutions clearly; aperture oblique, transversely-lunar ; in 
young specimens the decussated sculpturing of the shell on the parietal wall 
of the aperture is covered with a light callus as the animal grows, and ele- 
gantly marked with numerous fine, crowded, spiral lines ; in mature specimens 
this beautiful marking is entirely obliterated by the deposition of callus, but 
oa breaking the shell, the lines will be found to exist within ; peristome simple, 
acute, thickened within, ends slightly approximated, joined with a white 
callus. 
This species bears no close resemblance to any known American Helix. It 
belongs to the same group as H. Vancouver e7isis, Lea, but diff"ers in size, color, 
number of whorls, umbilicus, want of peculiar depression of the lip, by its 
beautifully decussated surface, and peculiar parietal wall of the aperture. I 
know of no species sharing this last beautiful peculiarity. In form alone, dead 
specimens may be compared with B. algira, Lin., of Europe, but the spire is 
flatter and umbilicus larger.

Shell perforate, ovate, heavy, white and wrinkled ; whorls 6, convex, the last 
ventricose, equalling in length b-1 of the shell; aperture ovate; peristome sim- 
ple, thickened within, the extremities joined by a heavy white callus, the 
columellar extremity slightly reflected so as partially to conceal the umbilicus. 
Belongs to the same group as Bui. dealbatus, Say, alternatus, Say, laclarius, 
Mke., Uquaiilis, Reeve, Schiedeanus, Pf., &c. The characteristics which form its 
differences are alike present in young and old specimens, and constant in all 
from the locality. I therefore consider it as well entitled to specific distinction 
as those named. 
Named from its greater size and more antiquated appearance, as compared 
with the allied species. 
Bidscription of a Phyllostome Bat from California, in the Museum of the 
Smithsonian Institution, 
BY S. F. BAIRD. 
Macrotus Californicus Baird. California Leafed-nosed bat. 
The ears of this species are very large, scantily haired, ovate and rounded at 
the tip. Their outer edge extends forward to a little behind and below the 
eye ; the inner edge is partially free. The two ears are connected by a mem- 
brane, which takes its rise about one-twentieth of an inch behind the anterior 
free edge of the ear, and is united to the corresponding strip of membrane of 
the opposite side, so as to form a kind of roof over the middle of the head, 
the entrance posterior. The tragus is narrow, lanceolate, naked and one-third 
the height of the ear. The nasal appendage is short, but rather higher than 
wide, and extending on the side and beneath the nostrils as a narrow margin. 
It is coated rather closely with short hairs. The lower jaw is slightly fissured 
anteriorly, with a small narrow wart on each side of the fissure ; a groove or 
furrow extends from the fissure along each side the lower jaw.
