THE NAUTILUS. 
eously, and, probably, at the same locality. In view of this con¬ 
clusion, also of the fact that the specimens are in some respects dis¬ 
tinct from any heretofore known to me, or, so far as I can learn, to 
any writer on conchological matters, I assume the responsibility of 
naming and describing them as follows : 
Olivella gracilis Gray. Yar. Gaylordi Ford. PI. II, fig. 14. 
Shell similar in outline to 0. gracilis , but much smaller, general 
color bluish-grey, with a well defined interrupted band of a lead’ 
black hue bordering the upper part of the final or body whorl. 
Smaller spots of a like hue also appear at the upper edge ot the 
fasciole. Circling the middle portion of the whorl is a number of 
irregular brownish lines, which also occur less prominently on the 
fasciole. In some specimens a splotch or two of the same color as 
the interrupted band referred to, appears on the upper part of the 
preceding whorl. Apex very acute and free from spots. Length of 
aperture rather more than one-half that of the shell; dorsal port ion 
of the extreme base creamy white. Average length of specimens 
9 to 10 mm., width 3’2 to 4 mm. Hab., Gulf of California. 
Mrs. Gaylord, for whom the variety has been named, is not only 
a practical collector, but an unusually earnest and capable con¬ 
chological student also. It gives me great pleasure, therefore, to 
associate her name with the beautiful specimens referred to. 
FERUSSACIA SUBCYLINDRICA AND TWO NEW SPECIES IN JACKSON 
CO., ALABAMA. 
H. E. SARGENT, WOODVILLE, ALA. 
The pleasure which thrills the field naturalist upon locating with 
in his range, a species previously unknown to the region, must be 
experienced to be appreciated. It is my privilege at this writing 
to report three such finds. 
Late last November, at the end of a shell hunt of two hours, 
which had among other things brought to light several fine speci¬ 
mens of H. obstrida Say var. y, I chanced to detect for the first 
time a specimen of F. subcylindrica L. 
Its station was a fiat surface rock about thirty feet square, at an 
angle of 30°, with a north exposure. Having a sack with us, my
