In this variety hardly any stripes are visible, except ujion the 

 body- whorl. 



Var. g. Ex albido pallide et obscure vh'escens, fascia basali lineatd 



lata; aperturd alba ; columella violaceo-subpurpured ; labii limbo 



vix pallidissime rubente. 

 Var. h. Sordide virescens lineis transversis obscuris vittata ; fascia 



basali sordide bruniied lata ; aperturd albd ; columelld violascente ; 



labii Umbo pallide rubente. 

 Var. i. Cinerascens ; fascid basali latd, lineatd, brunned; aperturd 



sordide albd; labii limbo brunneo-nigricante. 

 The ground-colour beneath the epidermis is rich brown, which is 

 exposed where the epidermis is abraded.

Var. k. Grandior, ex albido cinerascens lineis transversis obscure 



brunneis cincta ; fascid basali Uneato-vittatd brunned latd ; aper- 

 turd albidd ; labii Umbo purpurascente. 

 In this variety the ground-colour is browTi : the riband-like, 

 broad basal band is dark brown. 



Var. /. Productior, e brunneo cinerascens, vittis brunneo-nigricanti- 



bus cincta ; fascid basali latdbrnnneo-nigricante; aperturd obscure 



purpurascente ; labii limbo nigricante. 

 The ground-colour of this variety is brown, which becomes deeper 

 on the lower whorls, and is exposed where the epidermis is abraded.

In none of the varieties do the markings appear before the third 

 whorl, and in several only on the two last. 



This species varies in size from about 2\ inches long by 2 broad, 

 to 1^ inch long by 1^ inch broad. (W. J. B.) 



BuLiNUS GuiMARASENSis. Bul. tcstd obovutd, nitide glabrd, anfrac- 

 tibus 5 subventricosis ; lineis incrementi oblique longitudinalibt/s 

 striatd ; aperturd et labii Umbo albis. 

 Var. a. Ex-albido-subvirescens ; fascid basali obscuriore ; apice sub- 

 rose o. 

 Var. b. Anfractibiis superioribus, fascid suturali, ultimo fascid sub- 



basali castaneo cinctis ; apice castaneo-roseo. 

 This species is nearly allied to Bulinus citrinus, but differs from it 

 in many points. B. Guimarasensis is without transverse striae, and 

 the whorls are comparatively ventricose. In B. citrinus all the 

 striped varieties which I have seen are marked longitudinally. 



The var. b. of Bul. Guimarasensis has a narrow chestnut trans- 

 verse line very near the suture of the body-whorl, the base of which 

 body- whorl, below the transverse band, becomes greenish. A brown 

 stripe adjoins and borders the columella.^ 

 Var. a. is 2^ inches long by 1^ inch broad. 

 Var. fj. is less. 

 Hab. in insula Guimaras.
