XXXII. — Description of a neio SjJecies o/" Helix. 

 By Edgar A. Smith, Zoological Department, British Museum. 



Helix (Merope?) Barnaclei. 



Testa imperforata, conoideo-globosa, levis, tenuiuscula, nitidissima, 

 t'ulva, nigro-fiisco bifasciata ; spira conoidea, vix convexa, apice 

 obtusiusctilo ; anfractus 4|, convexiusculi, sutura distincta alba 

 sejuncti, lineis incrementi arcuatis sculpti, ultinius subventricosus 

 ad aperturam breviter deflexus, ad peripberiam albiis obsolete 

 carinatus, infra in medio impressus ; apertura obliqua, irre- 

 gulariter lunato-triangularis ; peristoma leviter incrassatum, 

 reflexum, albidum, extus castaneo marginatum, margine colu- 

 mellari recto, calloso albo. 



Diam. max. 24 millim., min. 21 ; alt. 15. 



Testa junior ad peripberiam anfr. ultimi acute carinata et fascia 

 lata alba, nigro marginata, cincta, anguste perforata. 



Shell imperforate in the adult state (narrowly umbilicated 

 when immature and acutely angled at the periphery), conoidally 

 globose, with a very shining surface, of a rich fulvous or deep 

 fawn- colour ; the upper whorls become gradually paler than 

 the last, and towards the apex are semitransparent horn- 

 colour and encircled by a single narrow dark brown line just 

 above the suture, which is white ; this line becomes much 

 broader upon the body-whorl, which has a second similar baud 

 beneath the more or less white periphery ; this is obsoletely 

 keeled or angulated near the upper end of the lip, the keel 

 vanishing altogether on the last half of the whorl ; whorls 4^, 

 a little convex, having no other sculpture than the arcuate 

 lines of growth (except in young shells, where they are obso- 

 letely spirally striated), the last somewhat ventricose, very 

 shortly deflexed at the aperture ; beneath paler or horn-colour 

 and a little concave in the middle or umbilical region ; the 

 aperture is very oblique, very irregularly triangular-lunate, 

 white within, banded with black and brown (the latter not 

 visible exteriorly) ; lip not much thickened on the outer and
