606 MR. S. HANLEY ON NEW INDIAN SHELLS. __[ Nov. 16, 
The specimen described seems old, though in fine condition; of 
course its characters will be modified in less-mature examples. I 
state this because I suspect that some young fragile shells from the 
Naga hills may prove identical.

Only four specimens are known to me, all from the Cottyam Hills : 
two are young and rather narrow in proportion to the fine but broken- 
lipped example I have described, which once belonged to the cele- 
brated Indian conchologist W. Benson ; it will be figured in the 
*Conchologia Indica’ (pl. 155. f. 4). 
4. Acuatina (GLEssuLa) tsts, Hanl.

pallida, nonnunquam vitta angusta fulva, lineis perparvis fulvis 
confertis circumeincta : vitta variabilis seu sepius versum basim 
anfractuum superiorum et supra medium anf. ultimi posita. 
Anfractus circiter 10, convert, sensim accrescentes, ad suturam

excepto) quam alti: apex obtusus. Apertura angusta, quartam 
partem totius altitudinis paululum superans, Columella brevis,

Mus. Hanley. 
A figure of this will be found in the ‘ Conchologia Indica’ (plate 
155. f. 5). The hair-like lines and narrow fillet seem peculiar to 
the species: the fillet, however, is neither constant, nor fixed as to 
position. 
5. Unio vuucanus, Hanl. 
T. solida, inequilateralis, subovata, viridis, undique (nisi fortasse 
ad extremitatem anticam) plicato-rugosa ; plice (seu tubercula 
elongata confluentia) undatim angulariter et oblique ordinate.

Costa umbonalis nulla ; area postica nequaquam concava. Lu- 
nula lata, haud multumimpressa. Margarita alba, viz minime 
iridescens. Margo cardinalis latus ; dentes cardinales solidi,
