add another to the Burmese and Malay forms represented in the hill 

 groups of that region. In 1866, I described another species, Sp. 

 Beddomei* from the Eastern hills near Vizagapatam (J. A. S. B. 

 Vol. XXXV. PI. II. p. 31). The present form differs from Sp. 

 Beddomei in several characters, the principal being the prominent 

 apex, the form of the sutural tube and the presence of a small lingui- 

 form process at the left side of the peristome near its base. The last 

 character indeed is quite peculiar, and serves alone to distinguish the 

 present species. In size, and somewhat in form, there is a decided 

 resemblance to the Burmese Sp. Avanum, in which, however, there 

 are not only important distinctions in the form of the peristome, the 

 recurved sutural tube, &c, but the operculum is also very different, 

 being flat precisely as in the Burmese forms of Pterocyclos, while in 

 Spiraculum Fairbanki, it is as convex as in Ptercyclos rupestris, or 

 Ft. bilabiatus. 



Mr. Fairbank only obtained 11 specimens of this interesting form. 

 Tbey were found in a Shola at some distance from Kodai Kanal, the 

 hill station on the Pulneys, on the road to the Kukal Shola.
