(2.) H. hortensis var. pallida Ckll. 
Magnolia, Mass. This variety is pale purplish or purplish-brown, 
without bands. 
(3.) H. hortensis var. quinquevittata Moq. 
Magnolia. This is yellow with five bands. 
'(4,) H. hortensis var. rufozonata CkIl. 
Magnolia. Three specimens. Straw colored with red-brown bands, 
five in number. 
(5.) H. hortensis var. subalbida Locard. 
Magnolia. Very pale yellow, or whitish, bandless. 
(6.) H. hortensis var. lutea Moq. 
Magnolia. Pale yellow and bandless. This specimen belongs 
also to hybrida Jeftreys, because it has the lip of the shell tinged pale 
brown. This variety, combining the characters mentioned, may 
accordingly be written var. lutea-hybrida. 
(7.) H. hortensis var. subglobosa. (Binney.) 
Shell greenish or brownish-yellow or honey-color. Parietal wall 
pale yellow, sharply defined from the darker (external) part of shell. 
Outer wall within white. This example, from Magnolia, is rather 
larger than the others, max. diam. 223 mill. This interesting variety 
is the H. subglobosa of Binney. 
The varieties above enumerated from Magnolia, Mass., were sent 
to me by Mr. J. A. Singley, who obtained them from E. W. Roper. 
They were marked “ introduced.” 
All the above varieties are known in Europe except subglobosa. 
Vars. vallotia, quinquevittata, subalbida and lutea were described 
from France orginally, while pallida and rufozonata were first de- 
scribed from England. 
Mr. F. R. Latchford informs me that the examples he has of H. 
hortensis, collected by Prof. Macoun on Anticosti Island, are some 
plain yellow, and others with five brown bands. These will belong to 
lutea and quinquevittata respectively.
