DESCRIPTION. OF A NHW SPECIES OF PAT 
AND REMARKS UPON A HYALINE 
By Gro. W. Harper, A.M., Principal of Woodward High School. 
PATULA BRYANTI, Harper. 
Fig. 1, dorsal view, magnified 3 diameters; fig. la, ventral view, magnified 3 diameters. 
Shell broadly and perspectively umbilicate, discoidal, nearly flat above, 
and deeply excavated below; whorls, five, gradually increasing, regu- 
larly ribbed, outer whorl bicarinate; color, light brown; aperture, small, 
rhomboidal; peristome, simple, acute, having its extremities united. 
Greatest width, 64, least, 54; height, 2 ; width of umbilicus, 44 mill. 
Habitat, found buried deeply under old logs. 
Locality, Mitcheli county, North Carolina. | 
Discovered by A. G. Wetherby, F. W. Bryant, and Geo. W. Harper. 
Notre.—The above species bears some resemblance to the carinated 
varieties of the P. perspectiva, and some may consider it a variety of 
the latter. If it proves to be so, then we are strongly inclined to the 
opinion that the P. cumberlandiana is only a carinated variety of the 
P. alternata, as the analogy between the two is very close.

HYALINA SIGNIFICANS, Bland. 
Fig. 2, dorsal view, magnified 3 diameters; fig. 2a, ventral view, magnified 3 diameters. 
Shell narrowly, but deeply umbilicated ; pale horn color, epidermis, 
smooth, shining; whorls, six, increasing slowly, last somewhat in- 
flated ; irregularly striate, smooth on under side; aperture, lunate; 
peristome, acute; spire, slightly elevated; base rounded, slightly in- 
dented around the umbilicus. 
There are three pairs of pearly teeth within the base of the last 
whorl, which are plainly seen through the shell. 
From the peculiar arrangement of the teeth, this shell is readily dis- 
tinguished from the H. multidentata, as the latter has its teeth 
arranged in rows of five or six in each row. It isa curious fact that 
as the H. significans grows old, its teeth gradually disappear. 2 
Norre.—This shell was found by Prof. A. G. Wetherby and myself, — 
while on an exploring expedition in east Tennessee, during the ©
