ble especially on the back of the shell opposite the aperture). Last 

 whorl oblong, convex, much higher than broad. Aperture oval, 

 much higher than broad ; peristome whitish, thick, strongly and 

 uniformly reflexed all around except on the columellar margin, 

 which is narrowed somewhat, and becomes nearly cylindrical, and 

 noticeably tortuous. A straight parietal callus unites the ends of 

 the peristome, and covers the umbilical region with a small callus.

Reeve and Pfeiffer have confused this species with H. oviformis 

 and its variety phenax. From these it differs entirely in the more 

 tortuous columella, smaller size and the obliquely descending wrin- 

 kles of the surface. 



Boettger (Nachrichtsblatt d. Deutschen Mai. Ges. 1889, p. 44) re- 

 ports it from the island of Nossi-Be ; but whether he had the true 

 Goudotiana or not I do not know. 



I have not seen the species, my description being compiled from 

 Deshayes' account of the original specimen. All doubtful refer- 

 ences have been purposely omitted in the above synonymy.
