has informed me in a note that the species I have described under 

 the name of decipiens is identical with this species, H. mirabilis, De F. 

 I suspect that he may be right in his opinion, and will take the ear- 

 liest opportunity of re-examining all the varieties of both, together. 

 " At present I will proceed to describe the principal varieties which 

 have occurred to Mr. Cuming, and which are unquestionably refer- 

 able to the mirabilis of De F." 



a. Shell rather thick and strong, with three dark bands, one of 

 which is close to the suture, and much narrower than the others. 



b. Shell very thin, with bands similar to the last. 



c. Shell with the spire much produced, and with three dark bands, 

 of which the middle one is very slender. 



d. Shell very thin, with a narrow sutural band, and a broader cir- 

 cumferential band. 



e. Shell thick and strong, with only a very narrow antesutural band. 

 /. Shell thin, and entirely destitute of bands. 



Helix fulgens. Hel. testa globoso-pyramidali, crassiusculd, im- 

 perforatd, Icevi, nitidd, albidd; spird prominuld, obtusd; anfractibus 

 A\ ventricosis, castaneo-niyroque fasciatis ; lineis incrementi tener- 

 rinie insculptis ; aperturd suborbiculari, inttis alba ; fasciis nigris 

 subconspicuis ; peritremate rejlexo, albo ; columella latiusculd, alba, 

 profundi ineunte. 

 Long 1*5, lat. 1*15 poll. 



Hab. ad Puerto Galero insulse Mindoroensis Philippinarum. 

 Two principal varieties of this brilliant species have been found 

 by Mr. Cuming; the one has black and chestnut-coloured bands, 

 beautifully relieved on a light-coloured ground, and the other has 

 the posterior part of each volution nearly white, one dark band close 

 behind the circumference, and three close-set dark bands in front. 



Helix chrysocheilus. Hel. testa subglobosd, crassiusculd, Icevi, 

 nitidd, imperforatd ; spird mediocri, obtusd ; anfractibus quinque, 

 ventricosis ; lineis incrementi tenuifer insculptis, epidermide palles- 

 cente indutis ; aperturd suborbiculari, intus alba ; peritremate in- 

 crassato, rejlexo, aurantiaco ; columella latiusculd, aurantiacd, pro- 

 funde ineunte ; labio interno tenui. 



Hab. supra folia arborum ad Banqui provincial Ilocos septentrio- 

 nalis ad insulam Lugon Philippinarum. 



A very beautiful species, and apparently very distinct from any 

 that have hitherto been noticed. It is extremely rare. 



The second paper is by G. B. Sowerby, Esq. 



Helix metaformis. De F. var. 



It seems proper to notice the following additional varieties of this 

 species, varieties which have been found by Mr. Cuming in the 

 Philippine Islands, viz. — 



a. Shell pale yellow brown, irregularly covered with a very pale 

 hydrophanous epidermis; circumference of the columella nearly 

 black; one pale brown band anterior to the circumference of the 

 shell ; apex white. Found on leaves of trees near Manilla.
