GLESSULA. 433 



Original description: " T. turrita, tenuis, sub lente capillaceo- 

 striata, nitida, pellucida, virenti-cornea ; spira elougata, apice 

 obtusula ; anfr. 7| convex!, ultimus 3 longitudinis vix aequans, 

 peripheria obsolete angulatus ; apertura vix obliqua, sinuato- 

 ovalis ; columella arcuata, oblique truncata ; perist. simplex. 



" Long. 9, diam. 4 mill., ap. 3 mill, longa, 2 lata." (Pfeiffer.) 



Hub. Ceylon (Thwaites) ; Haycock Mountain (Beddome). 



The type in the Cuming collection only measures 3'5 mm. in 

 diameter, not 4 as stated by Pfeiffer. There are also three speci- 

 mens, presented by Mr. Preston, one of which is composed o 

 nine whorls and measures 12 mm. in length and 3*5 mm. in 

 diameter. 



This species is allied to G. collettce, but has the whorls more 

 closely coiled and a broader base.

"Allied to G. sattaraensis, H. Ad. (=G. fusca, H. Ad., nom. 

 prceocc.), which is recorded from " Saharumpore, Ceylon," in the 

 Couch. Ind. ; but I do not know on whose authority. It was 

 described and Hgured from " Sattara, Bombay," by Adams, and it 

 may be remarked that the figure in the Conch. Ind. (pi. Ixxviii, 

 fig. 4) does not quite resemble that given by Adams (Proc. Zool. 

 Soc. 1868, pi. iv, fig. 10). I expect that the G. sattaraensis of 

 Dr. Jousseaume, cited from JVuvvara Eliya, is the present species, 

 which is more elongate and slender than the true G. sattaraensis" 

 (Sykcs.) 



"Topotyes before me are rather dark yellowish chestnut 

 colored, with sculpture of impressed vertical grooves. These 

 are rather widely separated on the later whorls, but close above. 

 Nearly two whorls at the summit are smooth. Length 8, diam. 

 2-9, aperture 2'9 mm. long whorls 6|. Compared with G. p. 

 taprobanica, this is a more slender shell ; hence the whorls appear 

 longer, and they are more evenly convex, the suture being less 

 narrowly impressed." (Pilsbry.) 



I find G. collettce is allied to G. gracilis, Bedd., but it is darker 

 in colour, the spire is a little more slender, and the aperture
