Species 32. (Mus. Cuming.) 



Melania sobria. Mel. tesl<i acute subulata, ad basin 

 subangulatd, solidinsculd, virente-olivaced ant rvfes- 

 cente,prope suturas obscure rnfo-maculald, anfractibm 

 undecim ad duodecim, planatis, tenue oblique striatis, 

 anfractibiis perpaucis primis minute costatis ; aperturd

The sober Melania. Shell sharply subulate, slightly 

 angled at the base, rather solid, greenish-olive or 

 reddish, obscurely red-spotted near the sutures, 

 whorls eleven to twelve, flattened, finely obliquely 

 striated, the first few whorls minutely ribbed; aperture 

 rather small, columella! - margin callously incurved. 



Lea, Pro. Zool. Soc. 1850, p. 181. 



Hab. Island of Siquijor, Philippines (in very small streams); 

 Cuming. 



A shell of solid growth, with a shiuing olive epidermis, 

 obscurely red-spotted beneath the sutures. The first few 

 whorls are minutely ribbed. 



Mr. Lea's M. cochlidium appears to me, from a careful 

 comparison of his types, to be a variety of this species in 

 which the last whorl is produced round the upper part 

 into a prominent thickened shelf. 



Species 33. (Fig. a, b, Mus. Cuming.) 



Melania juncea. Mel. testa elongato-subulatd, tenui, 

 pallescente-olivaced, pellucidd, rufo-Jlamniulatd, inter- 

 diiin purpureo-fuscd aut nigricante, suturis albidis. 

 anfractibiis duodecim, convexis, superne subdeclivi-in- 

 curvo, spiruliter sulcato-striatis, striis plus minus dis- 

 tantibus ; aperturd pun ii. 



The bulrush Melania. Shell elongately subulate, 

 thin, pale-olive, transparent, flamed with red, some- 

 times purple-brown or blackish, sutures whitish, 

 whorls twelve, convex, somewhat slopingly incurved 

 round the upper part, spirally groove-striated, striae 

 more or less distant; aperture small. 



Lea, Pro. Zool. Soc. 1S50, p. 189. 



Hab. Island of Luzon, Philippines (in Lake of Taal, and 

 in small streams) ; Cuming. 



A slender, gracefully subulate species, of light sub- 

 stance, marked with red flames in its typical state, but 

 varying in colour to a dark chocolate-brown, or black. 



Species 34. (Fig. 34 a, Mus. Cuming. Fig. 3 1 b, Mus. 

 V. d. Busch.) 



Melania Mtndoriensis. Mel. testa conico-subulatd, 

 tenui, tumiduld, virente-olivaced, anfractibus undecim 

 ad duodecim, plano-convexis, striis elevatis lirisque 

 planatis, quorum interstitiis excavatis, undique cingu- 



latis ; aperturd oblongo-ovatd, margine columellari 

 calloso-incurvo. 



The Mindoro Melania. Shell conically subulate, thin, 

 rather swollen, greenish-olive, whorls eleven to twelve, 

 flatly convex, encircled throughout with raised striae 

 and flattened ridges, the interstices between which 

 are excavated ; aperture oblong-ovate, columellar 

 margin callously incurved. 



Lea, Pro. Zool. Soc. 1850, p. 187. 



Hab. Puerto Galero, Island of Mindoro, Philippines (in 

 small streams) ; Cuming. 



Of a characteristic conically subulate form, encircled 

 throughout with more or less regularity by flattened ridges 

 or striae, between which the interstices are often exeavateil 

 with particular distinctness. Another character to be 

 noted is that the shell is painted with a profusion of red 

 dots, which appear only on the ridges, never in the in- 

 terstices. 



Species 35. (Mus. Cuming.) 



Melania cincta. Mel. testa subulata, tenuieuld, rufo- 

 castaned, ait basin fascia angustd luteold ciugulatd, an- 

 fractibus duodecim, plano-convexis, ad suturas submar- 

 ginatis, primis panels spiraliter sulcato-striatis et con- 

 spicue oblique corrugalo-plicatis ; aperturd parvius- 

 culd, margine columellari calloso-incurvo. 



The girdled Melania. Shell subulate, rather thin, 

 reddish-chestnut, encircled at the base with a narrow 

 yellowish band, whorls twelve, flatly convex, slightly 

 margined at the sutures, the first few spirally groove- 

 striated, and conspicuously obliquely wrinkle-plaited ; 

 aperture rather small, columellar margin callously in- 

 curved. 



Lea, Pro. Zool. Soc. 1850, p. 183. 



Hab. India. 



The narrow yellow band which is seen at the base of 

 this species is a very characteristic feature. In the con- 

 voluted portion of the -lull it i? concealed by the over-
