248 THE ZOOLOGIST. 
Ouse, &c. Queen Elizabeth’s Walk (B.) Hedge-banks, Hes- 
lington (H.) Museum Gardens, very abundant (H.) 
I am much surprised at the almost complete absence near the 
city of the genera Bulimus, Pupa, Vertigo, and Clausilia, and do 
not exactly know how to account for it. 
Bulimus obscurus.—Very rare. A single specimen at Castle 
Howard, some in Foss drift (R.), and two along the Dunnington 
road, are positively all that I have found or heard of. 
Pupa ringens.—I found one in drift from the Foss. 
Pupa umbilicata.— Abundant among the roots of the grass at 
the foot of the wall inside the well-known ‘“ Multangular Tower” 
(of magnesian limestone), in the Museum Gardeuns,* and still more 
so on the narrow ledges that run round it at some height from 
the ground. Drift of Ouse (R.) 
Pupa marginata.—Knavesmire (‘Observer’). Drift of Foss 
and Ouse. 
Vertigo pygmeéa.—F ound in peaty sand near Milford Junction 
about 1845 (B.) Very near my boundary. General (H.) 
Vertigo antevertigo.—Same as last species (B.) Ouse drift (R.) 
Abundant periodically at Askham (H.) Foss drift. 
Vertigo angustior.—Found also in peaty sand near Milford 
Junction about 1845 (B.) Some, presumably from this locality 
and presented by Mr. Backhouse, are in the British Museum. 
Vertigo edentula.—A few are to be found in the Far Wood at 
Askham Bog. Langwith (B.) 
Balia perversa.—Found in Acomb Wood in 1852, according 
to the ‘ Observer,’ but I distrust the record. 
Clausilia rugosa.—I have never met with it nearer to the city 
than Castle Howard, though Mr. Hey says it is quite common 
round Clifton. Longwith, Askham Bog, Holgate Lane, &c. (B.) 
Clausilia laminata.—Neither have I ever met with this close 
to the city, though it is found among the Ouse drift. Some 
specimens from Tadcaster are in the Bootham Museum. Castle 
Howard (R.) 
Azeca tridens.—Some at Thorparch. Castle Howard (H.) 
Ouse drift (R.) 
* If any future collector should discover Pupa secale at this spot, 
he need not record it as a new locality, since I am responsible for its 
occurrence there.
