BLANFOUD : AEIOPHANTA DALTI, K". STJBSP. 283 



AriopTianta interrupta (Bs.) : syn. Helix Himalayana, Lea. Bengal, 



Behar, Orissa, Vizagapatam (not Himalayas). 

 Ariophanta immerita (Blf.). South. Canara. Doubtfully separable from 



the last. 

 Ariophanta Bajadera (Pfr.) : syn. Helix ammonea, Yal. Bombay and 



neighbourbood. 

 Ariophanta intumescens, Blf. Mahablesbwar. 

 Ariophanta cysis (Bs.) : syn. Helix auris, Pfr. ; H. cystis, Ev. ; 



H. ampullar oides, Rv. ; and var. A. Dalyi, Blf. Southern 



Sahyadri, from Mysore to the Nilgiris. 

 Ariophanta thyreus, (Bs.) : syn. Helix rhyssolenima, Alb. Balarangam, 



Nilgiri and Anarmalai Hills, S. India. 



'No species is known from either the Himalayas or Ceylon. For 

 this reason the name Himalayana, applied to a species by Lea, is 

 misleading, and Benson's name interrupta, given a year later, should 

 be preferred. For similar reasons the name Nicoharica is objectionable. 



Theobald, in his Catalogue of the Land and Fresh-water Shells of 

 British India, p. 22, includes a species A. cyclotrema, from the 

 Sumeysur (Someshwar) Hills, at the base of the Himalayas, north 

 of Tirhut. I have a typical specimen given to me by Mr. Theobald, 

 and I have no doubt the species belongs to Playiispira or Trachia, 

 a section of Helix proper. Colonel Godwin- Austen has lately shown 

 reasons for removing the Moulmein H. retrorsa from Ariophanta,'^ and 

 uniting it to Hemiplecta, or some similar generic group. It thus 

 appears probable that Ariophanta proper is confined absolutely to the 

 Peninsula of India. So far as is at present known the dextrorse 

 forms of the same genus {Nilgiria, G.-A.) are similarly restricted, 

 except that some of them occur in Ceylon.
