of finger-like lobes, one short, and three united together longer 
(figs. 4a and 4). Itrepresents in a shorter form the same appendage 
in G. ochracca, in which there is one short and ten comb-lke 
notches, and the still longer one as represented by Semper in 
G. orophila, which has led to its being described as a feather-like 
gland and typical of the genus; a better knowledge of the 
animals shows it will only apply to a section of the genus. The 
elongate forms certainly form another, and may possibly have to 
be included in Bacillum. 
The prostate (fig. 4) is round, short, and solid; the hermaphrodite 
duct, much convoluted and thickened, forming a mass close to the 
albumen gland. The teeth of the radula do not differ from those 
of other species dissected. The formula is 
LG 9 ollie = 6 
or Wa a IL 4 PAD. 
GLrssuLA oRoBIA, Bs., small var. (Plate CLXILI. fig. 9.) 
Locality. Richila Peak, Western District. (No. 558° B.M.) 
(W. Robert). 
Shell elongately conical, shining, somewhat tumid; sculpture: 
irregular distant striation ; colour umber-brown with a greenish 
tint ; spire rather short; suture impressed; whorls 63; columellar 
margin slightly curved, truncate at base. 
Size: figured shell, maj. diam. 3°75; alt. axis 8-0 mm.

GLEsSULA CRASSULA, Reeve, Bs. MS. (Plate CLXII. fig. 24.) 
Locality. Darjiling No. 18.9.111.15, B.M. Typical from Hy. 
Blanford’s collection. 
Shell elongately conical, smooth and shining, slender ; sculpture: 
very few and distant striz ; colour umber- brown ; ; Ww horls Ger 
Size: maj. diam. 3:0: alt. axis. 75 mm. 
largest os 5:0, 5. 
These are all small and shorter than dimensions given in the 
original description, viz., 9 mm. 
In the Beddome collection are three specimens (No. 753) from 
the Naga Hills which bear a label in Col. Beddome’s handwriting, 
G. crassula. I have compared them carefully and drawn the apex 
(Plate CLXIV. fig. 18) much enlarged; it differs altogether in 
the sculpture from typical Darjiline examples of crassula (Plate 
CLXLY. fig. 14) in the Blanford collection (No. 18) (Plate CLXIYV. 
fig. 15). No. 753 is G. barakensis. 
From the Rarhichu in Sikhim I have 7 examples (No. 2481), 
which I consider a variety of the Darjiling form. The whorls have 
flatter sides, and the apex is much more blunt (Plate CLXIV. 
fig, 15). The largest measures a little over 9 mm. in length.
