Species 110. (Alus. Cumuig.) 



Heli.x s.\rcodes. Uel. testa vix unibilicatd, temtUsund, 

 l(Bm, fragili, stramuieo-corned, pellucidd ; apird pariim

 convexii, ultimo multo majore, injlato ; aperturd la-

The flesh-tinted Helix. Shell unibilicaled, verj- thin, 

 smooth, fragile, straw-coloured horny, transparent ; 

 spire but little raised, suture margined ; whorls four, 

 flatly convex, last whorl much larger, inflated ; aper- 

 ture very broadly lunar ; lip simple, columellar edge 

 thinly reflected. 



Pkeiffer, MSS. Mus. Cuming. 



Hub. Pliilippine Islands ; Cuming. 



This species has more tiie form of Filriita than II. Fi- 

 trinoides, by reason of the Ijroader and more inflated 

 growth of the last whorl. 



The shell represented at Fig. 1 17 a, i, named in Mr. 

 Cuming's cabinet II. suicentralis, Beck, proves to be a 

 variety of Sp. 150, //. ceralodes. 



Species 118. (Fig. a, b, Mus. Cuming.)

TiiF. remaukable Helix. Shell scarcely umbilicated, tur- 

 biuately depressed, solid, vei-y shining, horny yellow, 

 sometimes encircled by a n^d or blackish band ; spire 

 more or less raised, often reddish at the apex ; whorls 

 five to six, rather convex, the last angled below the 

 band ; aperture broadly lunar ; lip simple, acute, co- 

 lumellar edge a little reflected, covering the umbilicus. 



Pfeiffer, Pro. Zool. Soc. 1845, p. 41. 



Hub. Islands of Samar and Leyte, Pliilippines ; Cuming. 



A rather solid, shining, horny species, mostly encircled 

 with a conspicuous band. The shell can hardly be said 

 to be umbilicated.

Helix similaris. Uel. testa aiigiisti umbilicald, lubdr-

The similar Helix. Shell narrowly umbilicated, sorae- 

 w^hat deprcssly globose, minutely striated, diaphanous, 

 pale horny, sometimes encircled by a red zone ; spire 

 more or less raised ; whorls five in number, rather 

 convex ; aperture rotundately lunar ; lip white, re- 

 flected, columellar margin slightly dilated.

Whilst most Helices are extremely local in their liabila- 

 tion, this obtains a singularly wide range. It is found 

 with little variation in all the localities above recorded.
