than the following outer ones, which vary between 45 and 50, 

 giving the following formula 50 -f- 10 — 1 — 10 + 50. On the inner 

 lateral teeth the median cusps are very long, pointed and hooked ; 

 the outer dentical is small and the inner almost obsolete. The 

 outer lateral teeth become very rapidly bicuspid and narrow. 



The examination of other species of this genus must shew which 

 of the characters are to be regarded as particularly distinctive 

 in comparison with allied forms. The small size of the centre 

 tooth may be a useful character ; but the chief difference probably 

 lies in the genital organs which are quite peculiar, and require 

 further explanation and comparison. 



The typical species of Sesara are all from the limestone hills 

 about Moulmein. They are mfrendens, Gould, pylaica, Benson, 

 Ticlcelli and Attaranensis, Theob. Three other species, helicifera, 

 Basseinensis and mammillaris of Blanford are very probably also 

 referable to the genus ; they differ from the typical forms by pos- 

 sessing a thin simple outer lip. All three are also from the Bur- 

 mese province.

There can be no doubt that the two forms, described by 

 different authors under the above headings, are identical as to 

 species. Neither Benson nor Pfeiffer could have compared Gould's 

 original figure, otherwise they could not have mistaken the identity 

 of the two species. Theobald's TicJcelli, (Journ. Asiat. Soc. Beng., 

 1859, xxviii, p. 306; eadem, Pfeiffer; Hanley and Theob., Conch. 

 Icon., pi. xv, fig. 3), appears to differ from it merely by a sharp 

 peripherical keel.* Usually the two outer teeth of the basal 

 outer lip are much closer together, than they themselves are 

 with respect to the inner tooth of the lip. The former always 

 have a common base, which becomes especially apparent when 

 viewed from the internal side. It is extremely rare to find a
