CYPR&A. 21 



61. umbilicata, Sowb., (f. 42, 43, 44). — Testa pyriformi, 

 postice ventricosa, antice attenuata, lactea, fulvo-nebulosa, 

 maculis rotundia parvis fuscis ad dorsum variegata, spira 

 profundi umbilicata ; extremitate spirali ad latera depressa 

 subexpausa, extremitate antica in aream trigouam depressa ; 

 basi subplanata, minutissime granulata; apertura angusta, 

 tortua, postice retrorsa ; columella? et labii extremitatibus 

 productis, acuminatis, columella superne ventricosa denti- 

 bus brevibus tenuibus, infra medium inflata dentibus lon- 

 gioribus, plica terminali nulla ; labii dentibus tenuibus, an- 

 ticis longioribus. 



Note. — The resemblance of this species to 0. pantherina 

 is very superficial. The peculiar depression of the anterior 

 extremity, and obsoleteness of the terminal columellar tooth- 

 fold, would bring it into Cyprceovula, if that genus were 

 established. 



62. melanostoma, Leathes, (f. 34, 35). — C. testa ovata, ex- 

 tremitatibus prominentibus ; dorso rotundo, pallide fulvo, 

 cinereo fasciato, maculis rotundis albis floccato, ad apicem 

 subumbilicato, latere dextro ad extremitates tantum albo 

 marginato ; basi rotunda, alba ; apertura intus violacea, la- 

 this cula; dentibus columellas parvis interstitiis violaceo- 

 nigricantibus, labii rotundis interstitiis albis. 



Note. — This species is usually associated for comparison 

 with vitellus, but no specimens of it exhibit any tendency to 

 lateral thickening, and transverse lineation of the base and 

 sides. It is also of a pyriform shape, with the ends produced. 



63. lynx, Linn., (f. 85*, 86*, 87*, 88*).— C. testa ovata, 

 crassa, obtusiuscula ; dorso albido, fulvo et caarulescente 

 nebulato et guttato ; maculis fusco-nigrescentibus, hinc illic 

 interspersis ; hiatu dorsali angusto, lineari ; basi longitudi- 

 naliter callose univaricosa, alba ; lateribus albicantibus ; den- 

 tibus rotundis, brevibus, interstitiis vivide sanguineis. 



Note. — This species is subject to great variations in form 

 and colouring, among others, to one which has been re- 

 cently published as distinct under the name of C. Caledo- 

 nicus, Crosse, which is simply a produced and narrowed dis- 

 tortion, bearing the same relation to the normal form as 

 G. eglantvna (Arabica), G. Barthelemyi (moneta) , and several 

 others do to their respective species. 



64. eekones, Linn., (f. 156, 157, 158). — C. testa oblongo- 

 subpyriformi ; dorso subdcpresso, flavido, maculis minutis-
