This is merely a young shell dcscriijed by Dr. Pl'eifFer 

 from the circumstance of its not being referable to any 

 known adidt species. Two specimens were collected by 

 Mr. Cuming at the above-named locality in the leaf of a 

 palm-tree. 



Species 69. (Fig. a, b, Mus. Cuming.) 



Heli.\ HYDKOPnANA. Ilel. testd imperforatd, obovatd, 

 ienuiusculd, lutescente, fasciis rujis oniatd, nitidd, epi-

TiiK iiYDiioi'iiANous IIeli.x. Shell imperforated, ob- 

 ovate, rather thin, yellowish, ornamented by two red 

 bands, shining, covered with a very thin subpcUucid 

 hydrophanous epidermis ; spire very obtuse at the 

 apex ; whorls four to five, rather convex ; columella 

 nearly straight, broad, snowy-white, produced into 

 an obsolete tubercle, encircled by a black band ;

 lip rather thickened, but little expanded, white.

It is very much to be doubted whether this species is 



anytliing more than a local variety of the following. The 



shell is smaller and thinner in substance, but in structure 



and plan of colouring there is no difference whatever, ex- 

 cepting perhaps half a whorl less in convolution. 



Species 70. (Fig. a, b, Mus. Cuming.) 



Helix .metafoumis. Hel. testd imperforatd, oblongo- 

 ovatd, solidd, lavi, luted, apice rubescenle, fnaciit rufit

 anfraclilnis quinque, convexis, ultimo spird breriore .- 

 columelld crassd, dilatald, ba»i tuberculalo-lruncatd, 

 plerumque nigro-cingulald ; aperturd obliqud, lunalo-

 viter reflexo. 



The CONICAL Helix. Shell imperforated, oblong-ovatc, 

 solid, smooth, yellowish, reddish at the apex, vari- 

 ously ornamented with red bands and covcnd by 

 a thin epidermis; whorls five, convex, hist whorl 

 shorter than the spire ; columella thick, dilated, tii- 

 bercularly truncated at the base, generally encircled 

 with black ; aperture oblique, lunar-oval, milk-wbitt- 

 w ithin ; lip thickened, white, shortly reflected.

 Helix oeularis, Menke. 



Hab. Island of Luzon, Philippines ; Cuming. 



There is only one band in some examples of this species. 



and in others it is altogether wanting.

 This appears to be the coloured H. obtusa, described 

 with a figiu-e of the white variety at PI. XIV. Fig. 19.

 lumella flattened, slightly arched ; aperture nearly 

 circular ; lip slightly reflected, efi'used.
