Original description : " Testa ovato-turrita, solidula, cornea, 

 parum nitida, verticaliter costulato-plicata, sub-lente lineis minu- 

 tissiinis confertis spiralibus, sa3pe obsoletis, decussata ; spira 

 pyrumidalis, lateribus vix convexis ; apice obtusulo ; sutura pro- 

 funda. Anfr. 7| convex!, infra suturarn obsolete sub-angulati, 

 ultimus antice paulo ascendens. Apertura verticalis, truncata, 

 semiovalis ; peristoma obtusum ; columella mediocriter arcuata, 

 antice oblique truncata. 



" Long. 12, diam. 5 j, ap. long. 4, lat. 2 inm." (Blanford.)

" This shell resembles in form A. oreas, Bens., but it is distin- 

 guished from that and all other allied species by its stronger 

 sculpture. Possibly the two varieties should be ranked apart, as 

 there is considerable difference between them. A third form, 

 shorter and more tumid, occurs near Poona. As other intermediate 

 varieties probably exist, I prefer for the present classing all in 

 one species, but it may hereafter be desirable to distinguish 

 them.

Hab. India : Matheran, near Bombay. 



It is rather surprising that Blanford should have compared this 

 species with oreas, while overlooking its much closer affinity with 

 filosa described in the same paper, the sculpture being very 

 similar. The latter is, however, a larger shell with broader base 

 and acute apex. 



In typical specimens of G. lyrata the last whorl is not wider 

 than the penultimate and ascends a little in front, while the spire 

 is concave. The variety matheranica, on the other hand, has a 

 convex spire ; it is, moreover, considerably smaller, and the 

 sculpture is much less apparent on the base. The two forms are, 

 perhaps, as suggested by Blanford, entitled to rank as distinct 

 species, but I have not seen sufficient material to form a definite 

 opinion. Major Peile has sent me for inspection some shells 

 from Mahableshwar, one of which possesses 8 whorls and measures 

 13x6 mm. ; another, of 7| whorls, measures 11-5 X 5'25.
