58 SMITH : NEW SPECIES OF SHELLS. 



stated by Reeve and Frauenfeld. J This error in the locality 

 doubtless misled Kobelt, who however has noticed the marked 

 difference in the apices of the two species, observing that 

 ' sollte die Reeve'sche Art Wirklich einen spitzen Wirbel haben 

 und derselbe nicht bios erganzt sein, so musste unsere Form 

 von ihr getrennt werden.' 



The specimen figured in the ' Conchologia Iconica,' by 

 Reeve, is in very perfect condition and has the acute apex 

 depicted in the figure. It is moreover a more solid shell, of a 

 greener tint, with spiral colour-bands and distinct spiral striation, 

 and the shape is very different. Whether it be the same as 

 that characterized by Lea is a little doubtful as his description 

 does not well apply to Reeve's species. He says that T. ingalls- 

 iana is obtusely conoid and thin, that the spire is obtuse, 

 the whorls rather flat, and that the aperture is subangulated 

 below. On the contrary, P. ingalhiana of Reeve is acutely 

 conical, thickish (for a Paludina), has a sharp spire, moderately 

 convex whorls, and does not exhibit any angulation at the lower 

 part of the aperture. 



Kobelt's figure (plate xi. fig. 2) gives a fair idea of the 

 ordinary form of this species, but it does not indicate the 

 presence of the faint spiral carinae which are traceable in most 

 specimens.
