GlESSTJLA (EiSHETIA) SUBACULINA, D. sp., CoU. G.-A. No. 3555 

 B.M. (Plate CLiX. fig. 9.) 



Locality. Landomodo Trigonometrical Station. Type. N. Khasi 

 Hills (7 specimens); The ilaotlicritlian Ridge (No. :3556) (4 speci- 

 mens) ; South Jaintia (1 specimen). Tura, Garo Hills (/S". IF. Kemp). 



Shell elongately turreted ; sculpture irregular, well-developed 

 rather coar.^e striation, but varying much in difierent shells ; 

 colour ochraceous; spire elongate, sides flatly convex, apex blunt; 

 suture rather shallow; whorls 12, sides not quite flat; aperture 

 narrowly ovate : columella curving subobli(iuely, broadly trancate. 



Size : maj. diam. 7'ii5 ; length 31'0 mm. 



This approaches the Sikhim G. haculina Bs., but is rather 

 broader than that species, the whorls near apex increasing more 

 rapidly. It is not so smooth and shiny. 



No. 77 of Nevill's ' Hand list,' p. 170, Gless. lacuVtna — 3 Khasi 

 Hills, presented by me, are suhaeulina ; tlicy have been sent home 

 (1916) by Dr. N. Aunandale and compared by me. 



Glessula (Kishetia) SUBACULINA, G.-A., No. 1560 B.AI. (Plate 

 CLIX. tig. 4.) 



Conch. Ind. pi. svii. fig 5 as G. theohalcU, Hanley MSS. 



Locality. Teria Ghat, foot of Kliasi Hills (^Godwin- Austen). 



Shell elongately turreted, slender; sculpture: striation of growth 

 strongest below the suture and most regular on the 5th and tith 

 whorls ; colour umber-brown or dull ochraceous ; spire elongate, 

 apex fine ; suture shallow ; whorls 12, sides flat, proportion spire 

 to last whorl 100: 24-4; aperture narrowly ovate; peristome 

 outer lip thin ; columellar margin regularly convex, not solid. 



Size: maj. diam. 9'5 ; alt. axis 34'75 mm. 



There are two specimens in my collection now in the Natural 

 History Museum (No. 1580 B.M.); their history is of interest and 

 important with regard to the exact habitat of G. theohaldi, 

 Hanley. 



Considerable confusion surrounds this species, owing to the 

 authors of the 'Conchologia Indica' working apart when it was 

 passing through the press — one (Mr. Hanley) in England, the other 

 (Mr. Theobald) in India, dealing with shells from two very different 

 localities. Hanley first describes the shell very briefly of AeJudina 

 theohaldi. Conch. Ind. p. 9, 1870 ; in explanation of pi. svii. fig. 5, 

 from "Near the Salwen," he says, "Difiers from A.cassiacn, of which 

 it has been considered a variety, by its smoothness, more convex 

 ■whorls, &c." The sliell was therefore a Bacillum, and we can 

 presume the species recorded by Theobald from the Shan Stales was 

 also a Bacillum, vide a paper in the ' Journal of the Asiatic Society 

 of Bengal,' 1870 (not 1871 as given by Gude), vol. xxxix. p. 395.
