of finger-like lobes, one short, and three united together longer 

 (figs. 4rt and 4/j). It represents in a sliorterform the same append:ige 

 in G. ocliniciu, in which there is one short and ten comh-like 

 notches, and the still longer one as represented by Semper in 

 (r. orojihili', wliich has led to its being described as a ftather-like 

 gland and typical of the genus; a better kno-nledge of the 

 animals shows it will only apply to a section of the genus. The 

 elongate forms certainly form another, und 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 raduia do not differ from those 

 of other species dissected. The formula is 



16 . 1) . 1 . 9 . 16 

 or 25 . 1 . 25. 



Glkssula orobia, Es., small var. (Plate CLXII. fig. 9.) 



Locality. Eichila Peak, Western District. (No. 558 P.M.) 

 ( W. liohert). 



Shell elongately conical, shining, somewhat tumid; sculpture : 

 irregular distant striation ; colour umber-brown with a greenish 

 tint ; spire rather short ; suture impressed ; whorls Qh ; columelkir 

 margin slightly curved, truncate at base. 



Size: figured shell, maj. diain. 3-75 ; alt. axis 8'0 mm. 

 largest ,, 40 „ 90 ,, 



Glesscla ceasstjla, Keeve, Bs. MS. (Plate CLXII. fig. 24.) 



Locality. Darjiliug No. 18.9.iii.l5, P.M. Typical from Ily. 

 lilanford's collection. 



Shell elongately conical, smooth and shining, slender ; sculpture : 

 •7ery few and distant striie ; colour umber-brown; whorls 6|. 



Size : maj. diam. 3'0 : alt. axis. 7'5 mm. 

 largest ,, 8-0 „ 



These are all small and shorter than dimensions given in the 

 original description, viz., 9 mm. 



In the Peddome collection are three specimens (No. 753) from 

 the Naga Hills which bear a label in Col. Peddome's handwriting, 

 G. crassula. I have compared them carefully and drawn the apex 

 (Plate CLXIV. fig. IS) much enlarged ; it differs altogether in 

 the sculpture from typical Darjiling examples of crasstda (Plate 

 CI-XIV. fig. 14) in the Planford collection (No. IS) (Plate CLXIV. 

 fig. 15). No. 753 is O. baralcensis. 



From the Karhichu in Sikhim 1 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 CLXR'. 

 fig. 15). The largest measures a little over 9 mm. in length.
