 pressed, lenticular, thiu, pellucid, light chestnut or 

 pale yellow, ornamented with a brown or black band 

 at the suture ; suture sometimes edged witii white ; 

 whorls five, rather flattened, the last sharply keeled ; 

 umbilicus rather large, wide open ; aperture nearly 

 horizontal, compressly ovate ; lip thin, simple. 



Hab. Dalaguete, Plulippines; Cuming. 



A tliin flatly depressed transparent shell, formed very 

 nmch like a Solarium, cncii-cled with a characteristic dark 

 baud next the suture.

The wheel Helix. Shell umbilieatcd, depressly lenti- 

 cular, rather flat above, inflated at the base, keeled, 

 irregularly crisply wrinkled, the basal ribs being 

 stronger ; dull white or fawn-colour, encircled with 

 narrow chestnut bands, two above and" one below the 

 keel, which is sharp and undulated with white tuber- 

 cles ; whorls four to five, flattened, the last suddenly 

 deflected anteriorly ; umbilicus middling, open ; aper-

 margins joined, basal margin one-toothed. 



Carocolla rota, Broderip, Pro. Zool. Soc. 1841, p. 45. 



Hab. Island of Sitjuijor, Phili[)j)ines ; Cuming. 



This very pretty species is well chnracterizcd by its 

 numerous concentric crisped wrinkles, while the keel at 

 the periphery of the shell obtains a crimped pattern. 



Species 129. (Fig. a. A, Mus. Cmning.) 



Helix .marginata. Ilel. testd umbilicatd, lenticulan, 

 acute carinatd, oblique striata, pallide/ulrescenle,fa»ciii

 quatuor, planiusculis, ultimo jujcta aperturam mtperne 

 injlalo, valde deflexo ; carina albd, usque ad apicem com- 

 spicud ; umbilico angmto, pertio ; aperlurd horizon- 

 tali, ellipticd ; peristomate simplici, marginibusjnnctit. 

 supero late expanse, basali re/lexo. 



The margined Helix. Shell umbilieatcd, lenticular, 

 sharply keeled, obliquely striated, pale fulvous, orna- 

 mented with numerous red lines; spire but little 

 raised ; whorls four, rather flat, the last inflated at 

 the upper part near the aperture, very much deflected, 

 keel white, conspicuous as far as the apex ; umbilicus 

 nan'ow, open : aperture horizontal, elliptical ; lip 

 simple, margins joined, upper margin broadly ex- 

 panded, basal reflected.

 Helix srabrosa, Ferussac. 

 Helix Grayana, Pfcifter. 



Hab. Island of Camiguing, Philippines ; Cuming. 



Dr. Pfeifi"er refers this species to H. marginata of Mui- 

 ler, but it is diflicult to identify it without some doubt. 



Species 130. (Fig. a, 4, Mus. Cuming.) 



Helix GaLLINCLa. Hel. testd umbilicatd, lenlicuiart, 

 acute carinatd, solidd, flavescenti-grised, /dsciis hohhuI-

 crassato, marginibus callo tenui junctis, batali rrflezo, 

 ad umbilicum mediocrem, perrium arcuato. 



The little men Helix. Shell umbilieatcd, lenticular, 

 sharply keeled, solid, yellowisli-grcy, omomentcd 

 with some rctl bands and n hydrophanous epidermis 

 forming light triangular blotches ; whorls four to fire.
