remain the shell figured in the Conch. Misc. [though not de- 
scribed] which we all unite in considering= M. menkeana.

subvar. microstoma. 
A small and remarkable form, apparently from the same locality 
as typical var. B.of Benson, from which it can be distinguished 
by the small and almostrounded aperture, the more produced and 
perfect spire, and whorls less convexly swollen; two brown 
bandsat the base, as in typical var. B., but the upper whorls also 
possess a distinct central band; two specimens have subnodular 
ribs on the last two whorls, the upper ones being perfectly smooth, 
the third specimen has nodulose ribs on the three last whorls, 
the fourth has them on the last whorl only; these nodulose 
ribs are variable in number and relatively distant.

Melania spinata, Godwin-Austen, P. Zool. 8. 1872, Kopili River. 
This remarkable form, excellently figured by the author 
[pace M. Brot], preserves its characteristics in both young and 
adult. M. Brot makes the strange error of supposing it might 
be the young of the form figured [correctly] as M. episcopulis, 
Lea, in the Con. Indica; I have both forms in all stages, and 
need scarcely say that they are widely different. Possibly, indeed, 
it might also be classed as an extreme variety of M. variabilis ; 
the peculiar, “foliaceous”” tubercles are very characteristic. 
It bears also some resemblance to a form of Mel. baccata, Gld.
