28 LAND AND FRESHWATER 
Amended description. 
GLessULA NEVILLI, G.-A. No. 447 B.M. 
Locality. Toruputu Peak, Dafla Hills (Godwin-Austen). 
Shell finely elongate, turreted; sculpture, well-marked close 
irregular striation ; colour white; spire very slender and lengthened, 
apex blunt; suture impressed; whorls 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 Nulla, Durrang District. This has a 
very smooth surface with very indistinct 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 feet above sea-level, andthe Pichola 
Nulla low down and quite out in the plains, I now note, 40 years 
later, there is a difference something more than “ far finer speci- 
mens,” and that those from the Granite Peak are very different, 
particularly in size, proportion, and sculpture. Many conchologists 
would consider them distinct species— however, it 1s sufficient that 
G. nevilli stands for the mountain form, the one first found by me, 
and that of the plains be considered a variety major. 
3a. The Miri Hills. 
From the great Valley of the Subansiri no species of Glessula 
have been received ; it is a large unworked area of 2500 sq. miles. 
4. Eastern Assam with the Singpho Hills and Patkow Range. 
Glessula maiamensis, n. sp. Pl. CLX. figs. 10-11. 
dihingensis, n. sp. Pl. CLXIV. fig. 4 (apex). 
GLEssULA MAIAMENSIS, n. sp. No. 1737. (Plate CLX. fig. 10.) 
Type. 
Locality. Maiam Peak, Singpho Hills; a single specimen 
(M. Ogle). 
Shell oblongly turreted, rather tumid; sculpture: strong, 
rather distant, engraved striation, showing strong near suture; 
colour ochraceous with a greenish tint; spire elongately conoid,
