Original description : — " A. testa subcyliudraceo-turrita, stria- 

 tula, obsolete et minutissime spiraliter decussata, polita, trans- 

 lucente, luteo-cornea ; spira versus apicein ad latera subconvexa, 

 vertice obtuso, sutura distincte impressa ; anfractibus 8, sub- 

 convexis, brevibus, 4 ultimis in diametro lente accrescentibus, 

 ultimo subtus rotundato \ longitudinis aequante ; apertura sub- 

 obliqua, ovata, superue subtusque angulata, marginibus callo 

 juuctis, coluniellari leviter arcuato, oblique truncato, dextro 

 basalique tenuibus. 



" Long. 12, lat. 4 mill. Apert., long, 3, lat, 2^ mill.*' (Benson.)

" The nearest JS'ilgiri form is A. corrostda, Pfr. The more 

 cylindrical form below, the sculpture, shorter whorls, &c., safely 

 distinguish it." (Benson.) 



"A type-specimen sent me from Mahableshwar by Mr. Fair- 

 bank, and a few other examples I have seen in the Benson 

 collection and elsewliere, are all young shells with unformed lips. 

 It is smaller than hehes, but I cannot point out how it differs 

 otherwise.'* (Beddome.) 



While agreeing that the two forms are closely alUed, they 

 appear to me sufficiently distinct to be retained as separate 

 species. G. hehes is not only proportionately larger but the last 

 whorl is shorter in proportion to the spire than is the case in 

 fairhanli, a feature which would still further be emphasized if one 

 or two whorls \vere added to the latter, whereas the reverse 

 would be the case if it were an immature form of hehes. 

 Glessula fairhanhi differs from G. hehes principally in the convex 

 upper part of the spire which becomes cylindrical at the last 

 three whorls. It further differs in being more polished, in tlie 

 striae being much finer, and in the whorls being less closely 

 coiled; all, except the last whorl, show numerous opaque, 

 narrow, spiral lines. Hanley's figure of the species is very 

 good. 



A specimen in the British Museum, from the type-locality, 

 possesses 8| whorls, but it has the same dimensions as the 

 type. 



Major Peile possesses a single specimen from Mahableshwar 

 composed of eight whorls.
