 remain the shell figured in the Conch. Misc. [though not de- 

 scribed] which we all unite in considering=Jf. merikeana.

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 almost rounded aperture, the more produced and 

 perfect spire, and whorls less convexly swollen ; two brown 

 bands at 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. episcopalis, 

 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. variab'ilis ; 

 the peculiar, " foliaceous " tubercles are very characteristic. 

 It bears also some resemblance to a form of Mel. baccata, Gld.
