AMPHIDBOMUS. 189 



This species in contour approximates most nearly to A. physalis, 

 but the shell is thiuneraud is ornamented with narrow pale brown 

 spiral fasciic. The specimen figui'ed in Conch. Ind. only possesses 

 two bands, whereas the type, figured by Chemnitz, has three. 

 The shell depicted by Keeve, from Benson's collection, is also 

 encircled by three bauds. The specimen in the Benson collection 

 — presumably the one figured by Eeeve- — kindly forwarded to me 

 for inspection by Dr. L. Doncaster, in charge of the University 

 Museum of Zoology, Cambridge, has somewhat deteriorated, having 

 a considerable hole in the body-whorl and two small ones near the 

 parietal callus ; the peristome is also damaged. This is probably 

 owing to its having been stuck on a tablet. The above diagnosis 

 has been drawn up from this shell.

Original description : — " Testa subobtecte perforata, ovato-conica, 

 tenuiuscula, oblique striatula, albida, niteute ; spira conica, apice 

 obtusato ; sutura leviter impressa ; anfractibus 5| superne sub- 

 planatis, primis granulatis, caeteris striis spiralibus minutissimis 

 decussatis, ultimo tumidiusculo ^ longitudinis aequaute, ad peri- 

 pheriam plerumque angulato, apertura ainpla, obliqua, truucato- 

 pyriformi ; perisfomate expanso, marginibus refiexis, callo tenui 

 junctis, columellari superne latissimo, appresso, oblique leviter

Long. 27-28, diam. 1(5-17 mm. ; long. ap. 14-16, lat. 9-10 mill. 



Ilab. India : Khoonda Ghat, Nilgiris (Jerdon) ; Anamullay 

 Hills (Beddorne). 



" Well distinguished from the Cingalese species : alhizonatus, 

 ceylanicus, and intermedius, by its ventricose form, the more ample 

 aperture, and the mode of sculpture. A perfect specimen in the 

 Museum of Indian House and a young one from Dr. Jerdon have 

 the periphery angulate, an adult specimen of Dr. Jerdon's being 

 deficient in this feature." (Benson.)
