﻿150 Gotlwin-Austen — New species of Ali/cceincs. [No. 3, 



Hahitat. — Foot of the Bhutan Himalaya at the debouchement of the 

 Barovvli River, Assam ; collected by Mr. J. Burt, to whom m}^ thanks are 

 due for this and some other interesting shells. 



It is close to A. 'polygonoma^ but the form of constriction is slightly dif- 

 ferent, the peristome is well crenulated, and tlie sculpture stronger. At 

 Kamakia hill near Gowhatty, I obtained specimens of an Alycceus still 

 nearer in form io polygonoma, only that the sutural tube is but about half 

 the length, ending abruptly, while in polygonoma it is long and thread- 

 like. I shall describe it in my next paper. 



A. crenatus was found as far east as Shiroifurar, also at Kezakenomih 

 and Yemai. 



A. Ingrami, var. is the commonest form in the Naga Hills and has a 

 great range in altitude, being found at Dimapur in the Dunsiri valley under 

 300 feet and as high as 7,000 feet at Khunho Peak on the Burrail range, also 

 at Laisen Hill and Sikhami, and on the east side of the Munipur valley on 

 the slopes of Nongmaiching and Mungching. 



A. Nogaensis I have from Kezakenomih, Kopamedza, Prowl, Laisen, 

 and Nongmaiching. 



A. Khasiacus occurred as far east as Kopamedza Peak, where it was 

 associated with the nearly allied form above described, A. multirugosus. 



A. urnula, Bens, is a very abundant shell all along the Burrail range, 

 it retains the tjqie form more persistently than any species of the genus 

 known to me. Very fine large specimens were collected at Kezakenomih, 

 Naga Hills ; dimensions, alt. 0-20," diam. 0-20". 



A. cUagonius and A. C7^ispatus, I found again in the Dunsiri valley, 

 Dimapur, and lower spurs of the eastern Burrail. 



A. prosectus, Bens., so common in the Khasi Hills, is very rare in the 

 easte;:ji Naga Hills and I procured 2 or 3 specimens only ; these shew a 

 transition, for they are not quite identical with the type form from Teria Ghat.
