Original description : " Testa pyramidali, turrita, tenuis, cornea, 

 polita, nitida, levis, vix striatula ; spira elongate conica ; apice 

 sub-acuto ; sutura impressa, minute corrugata. Anfr. 8 convex!, 

 ultimus longitudinis vix sequans, subtus rotundatus. Apertura 

 fere verticalis, ovato-oblonga ; peris torn a obtusum, albescens ;. 

 coluniella valde arcuata, antice oblique truncata. 



" Loug. 12|, diam. 4'4, ap, long. 4, lat. 2| mm." (Stanford.) 



Hob. India : Singhur near Poona (Blanford). 



" This is allied to the Nilgiri G.jerdoni, Bens., but the sides of 

 the spire are less convex, the shell being more regularly pyramidal 

 with a less obtuse apex. In some of the specimens of this species- 

 collected alive, but in which the animal had subsequently dried 

 up, I found young shells. It would thus appear to be viviparous. 

 I have observed the same circumstance (the ocurrence of youngf 

 inside the old one) in G. cassiaca, Bs. In other species of this 

 genus I have found small round eggs with a calcareous shell, but 

 these may be hatched, before they are deposited by the parent." 

 (Blanford.) 



The Cuining collection in the British Museum comprises five 

 specimens from the type locality, which measure 12 x 4-5 mm, 

 I possess shells from Poona, received from the late Colonel 

 Beddome, which are a little darker in colour than the type and 

 have the apex a little more acute. 



G. singhurensis is allied to G. naja, Pilsbry, but it is smaller 

 and has the last whorl proportionately higher.
