Ilab. Philippine Islands. 



A thin shining ivory-white shell, tinged with canker- 

 green, more especially next the suture. 



Species 1266. (Mus. Cuming.) 



Helix lacera. ITel. testa imperforald, oblongo-ghbosa, 

 solidiusculd, oblique tenuistriatd, fulvo-brunned, epi- 

 dermide hi/drophand oblique slrigatd ; spird tumidd,

 turas minute marginatis ; aperturd oblique ovatd, labro

The torn Helix. Shell imperforated, oblong-globose, 

 rather sohd, obliquely finely striated, fulvous-brown, 

 obliquely streaked with a hydrophanous epidermis; 

 spire swollen, very obtuse; whorls four, slightly con- 

 vex, minutely margined at the suture ; aperture ob- 

 liquely ovate, lip reflected ; columella very broadly 

 callously appressed. 



Pfeiffer, Pro. Zool. Soc. 1851'. 



Ilab. Philippine Islands. 



Of a peculiar oblong-globose form, very broadly callous, 



appressed at the columella, difl"cring characteristically in 



form from any of the species collected in the same locality 



by Mr. Cuming. 



The liEALTiFUL Helix. Shell narrowly umbilicated, 

 depressly orbicular, excavated around the umbilicus, 

 olive-brown, broadly chestnut-banded below the pe- 

 riphery and around the umbilicus ; spire convex, spi- 

 rally minutely grooved, arcuately striated, the stria? 

 being faintly plicated at the suture ; suture rather 

 impressed ; whorls five, convex ; aperture obliquely 

 lunar, lip simple. 



Pfeiffer, Pro. Zool. Soc. 1854. 



Nab. Ceylon ; F. Layard. 



Very closely allied to U. Juliana. 



Species 1268. (Mus. Cuming.) 



Helix microspira. Jlel. testa imperforald, globosd, in- 

 Jlatd, l<pvigatd, albidd, fasciis duaiiu purpureo-mgris 

 cinctd, epideniiide corned nitente induid ; spird parrd, 

 obtusd; anfractibus quatuor, convexis, ultimo maxinw, 

 tumido ; aperturd ampld, late lunari, labro rijleio ; 

 columelld lati calloso-appressd. 



The small spired Helix. Shell imperforated, globose, 

 inflated, smooth, whitish, encircled with two purple- 

 black bands, covered with a shining horny epidenuis ; 

 spire small, obtuse; whorls four, convex, the last 

 very large, swollen ; aperture large, broadly lunar, 

 lip reflected; columella broadly callously appressed. 



Pfeiffer, Pro. Zool. Soc. 135-1. 



Ilab. Philippine Islands. 



Tliis species is closely allied to //. coccomelos, but the 

 last whorl is much larger and more inflated. 



Species 1269. (Mus. Cuming.) 



Helix difficilis. Uel. tfstd imperforatd, orbiculari- 

 depressd, subinflatd, albidd, fulBescenie tinctd, zonia 

 bruntieia tribus distant ibiis cingulald ; spird brevi, ob- 

 tusd ; anfractibus quatuor, plano-concexis ; aperturd 

 subampld, subquadrato-lunari, labro refiexo ; columeUd 

 latissime calloso-appressd. 



The difficult Helix. Shell imperforated, orbicularU 

 depressed, rather inflated, whitish, stained with ful- 

 vous and encircled with three distant brown lones ; 

 spire short, obtuse ; whorls four, flatly convex ; oper- 

 turo rather large, somewhat squarely lunar, lip re- 

 flected ; columcll.i very broadly callously appressed. 



Pfeiffer, Pro. Zool. Soc. 1854. 



Ilab. Philippine Islands. 



Of thc'samc typical character as the preceding species, 



but more depressly convoluted.
