smooth, and has the peculiar glossy surface which is so characteristic 

 of this species. It is at this point, the commencement of the fourth 

 volution, that the irregularity of growth commences, and is indicated 

 hy a deep erosion. What caused the sudden depression of the upper 

 part of the succeeding whorls is not evident, hut I am convinced that 

 it is abnormal. M. Granger points out that the upper part of the 

 operculum does not fit the aperture, a feature not shown in his figure. 

 Such being the case practically proves the abnormality of the shell, 

 for in this genus the operculum is invariably modelled to the form of 

 the aperture. The latter is precisely similar to that of A. polita, of 

 which A. pagoda, Morelet, 1 is a synonym. The interior is of the same 

 deep purple-brown tint, the columellar margin is reddish, within the 

 outer lip is a slight thickening, and the extreme margin is almost 

 black, all of which peculiarities are characteristic of A. polita. This 

 species occurs commonly in Camboja, 2 the country whence A. Brohardi 

 was obtained.
