It is difficult to say whether this little shell should be regarded as 
a distinct species, of the same group as Str. Perotteti. Petit, and Sir. 
Watsoni, nob. or whether the three should be considered as varieties of 
the same species. The differences between such specimens of the 
three forms as we have obtained are indeed sufficiently striking, and 
such as are usually treated as indications of specific distinction. 
While the typical Str. Perotteti, has the peristome furnished with 
3 teeth and Str. Watsoni with from 3 to 5, one of the specimens of 
Str. Footei received from Mr. Foote possesses but one tooth, viz. on 
the outer lip, while another, a distorted shell, has 2 palatal teeth. 
The latter species is moreover smaller than the first mentioned and 
larger than the second. On the other hand, it is clear that the 
number and development of the teeth alone cannot be regarded with 
certainty as a specific character, for we find that both Str. Perotteti 
and Str. Watsoni vary to some extent in this respect as well as that 
before us. Several minor differences which are perceptible when 
single specimens of the three Streptaxes are compared, are found to 
vary in shells undoubtedly of the same species, such as the size of 
the umbilicus, the depth of the sutural notch in the peristome, the 
striation of the whorls, &c. On the whole we think it more pro- 
bable that the Patchumullay shell is a local variety of Str. Perotteti 
than a distinct species.

This little shell belongs to a type distinct from that of Ennea 
Pierrei and the other S. Indian species, and is more nearly allied to 
the Cuttack sp. E. seriola. From this it is distinguished by its more 
conoidal form and the possession of two well developed parietal, and
