In 1872 God win- Austen stated that " the type of A. casiaca 

 in Benson's collection is a shell I obtained in the Naga Hills, 

 but never in the Khasi ; ' ' the latter being a different species, 

 which he described in 1875 as Glessula orthoceras. The local- 

 ity "Cassia Hills" given by Reeve on Griffith's authority is 

 erroneous. 



A small specimen stated to be from the N. Cachar Hills, is 

 figured, pi. 1, figs. 6, 7. It measures : length 52, diam. 10, 

 length of aperture 11 mm. The apex is broken. Fig. 5 is a 

 copy of Reeve's type figure. 



4. B. THEOBALDI (Hanley). PI. 1, fig. 8. 



"Differs from A. cassiaca, of which it has been considered 

 a variety, by its smoothness, more convex whorls, etc." (Hani. 

 & Theol).). 



Near the Salwin river, Shan States (Fedden).
