Amended description. 



Glessuia nevilli, G.-A. No. 447 B.JI. 



LocaUti/. Toruputu Peak, Dafla Hills [GoJivin- Austen). 



Shell finely elongate, turreted ; soiiliiture, well-marked close 

 irregular striutioii ; colour white; spire very slender and lengthened, 

 apex blunt; suture impressed; whoris 12, the six last almost 

 equal in diameter ; aperture small, narrowly and vertically ovate ; 

 columellar margin convex. 



Size : maj. diam. 2'25 ; length 14 mm. 



Var. major, G.-A., Pichola ^'ulla, Durrang District. This has a 

 very smooth surface with very indistiuct striation, and has a green 

 tinge. The largest specimen measures 17*75 mm. in length by 

 3'5, and has 12 whorls. 



Although I refer to the Toruputu habitat of the Granite Peak on 

 the main mountain mass 7322 I'eet above sea-level, and the Pichola 

 Nulla low down and (juite out in the plains, I now note, 40 years 

 later, there is a ditt'erence something more than " far finer .speci- 

 mens," and that those from the Granite Peak are very different, 

 particularly in size, proportion, and sculpture. Man}' oonchologists 

 would consider them distinct species — however, it is sufSoient that 

 G. nevilli stands for the mountain form, the one first found by me, 

 and that of the plains be considered a variety major. 



3 a. The Miri Hills. 



From the great Valley of the Subansiri no species of Glessula 

 have been received ; it is a large unworked area of 250U sq. miles. 



4. Eastern Assam ivith the Sinypho Hills and Patlcoi Range.
