GLESSULA. 441 



in size and shape ; their dimensions are as follows : fig. 138 a, 

 26xl2mm.; fig. 1386, 25 x 11-25 mm.; tig. 138 c, 24x9-75 mm.; 

 fig. 138 d, 23-75 x 9 mm. In the British Museum are four 

 shells from Timievelly, composed of 8| whorls and measuring 

 19 x 7'75 mm. 



Var. exigua, n. 



Differs from typical jilosa, besides being smaller, in having 

 the whorls more tumid and the suture deeper ; the last whorl also 

 contracts somewhat towards the aperture. 



Length 12-5 mm., diam. 6 mm. (8 whorls). 



Hob. India : Sirumullay Hills, Dindigul. 



This form I found in the Beddome collection intermixed with 

 G. subfilosa.

Original description : " Testa elongato-turrita, tenuis, fulvo- 

 cornea, distincte plicato-striata ; spira elongata, ad apicem sub- 

 obtusa, elongato-conica ; sutura impressa ; anfractus 10 planiusculi, 

 ulthnus subcariuatus ^ longitudinis tortius vix asquans ; apertura 

 lunato-subovalis ; peristoma tenue ; columella valde arcuata, 

 oblique abrupte truncata. 



"Long. lb', diam. 5 mm.; apertura 5 mm. longa, 3 lata." 

 (Beddome.) 



Hob. India : Sirumullay Hills, Dindigul ; Kurnool (Beddome). 



"The prominent sculpture is like that of filosa, but it is a 

 very much smaller shell, with a much more elongated apex." 

 {Beddome.) 



The type, which is in the British Museum, appears not quite 

 full grown ; it possesses 9| whorls, and measures : length 17'5 mm., 

 diameter 6*5 mm. It will be seen that these details do not agree 

 with those given by Beddome when describing the species. 



The principal character separating this species from G.filosa is 

 the attenuated spire, concave near the apex, which is obtuse, not 

 acute as in the latter. The aperture is also less high in proportion 

 to its width.
