DoMBEYA FASciATA. Tesia ovata, tenuis, ferrugineo-virens, 

 fusco spiraliter fasciala, creberrime plicato-striata et lineis vol- 

 venlibus minimis decussata ; spira acuta ; anfr. 6 ventricosis ; 

 sutura pallida, marginata : apertura semilunaris ; columella alba, 

 plica acuta instructa. Long, f , lat. |- poll. Hah. River Concon, 

 Chili. 



Allied to Chilina Jluctuosa^ D'Orb., but is more regular in form, 

 more ventricose and more solid ; and is noted for its very minute 

 revolving lines, its bands, and its pale suture. 



DoMBEYA OBOVATA. Testa obovata, solidula, pallide olivacea, 

 longitudinaliter colore saturation fulguralim virgata : spira curta, 

 anfr. 6, convexis, ultimo magno, antrorsum attenuate, postice 

 sub-angulato : apertura magna, elongato-ovata ; columella alba, 

 sub-recta, bene plicata : interior livescens. Long. |^, lat. J- poll. 

 Hah. Concon River, Chili. 



In size and marking it is similar to C. major, Gray, but is less 

 broad, and the suture much less impressed. It is much larger 

 and more ventricose posteriorly than C. pulchra, D'Orb., and 

 much less pictured. 



LiMNEA voLUTATA. Tcsta parva, tenuissime striata, fulva,cy- 

 lindraceo-ovata : spira decollata ; anfr. 2-3 superstitibus, obliquis, 

 convexiusculis ; sutura modica : apertura ovata, dimidiam testae 

 superans ; columella rufa, valde sinuata. Long, y^g-, lat. ^- poll. 

 Hah. Oahu. 



Much smaller than L. Oahuensis, Souleyet, and with less tumid 

 whorls, sloping gently to the suture. The somewhat cylindrical 

 aspect of the shell is peculiar. 



LiMNEA LEPiDA. Testa gracilis, elongata-conica, fragilis, di- 

 lute cornea, striis volventibus remotis et striis incrementalibus 

 undulosis decussata : spira acuminata ; anfr. 5 obliquis, convexi- 

 usculis : apertura magna, semilunaris, expansa ; plica columellari 

 pernotabili, acuta. Long, f , lat. ^ poll. Hah. Lake Vancouver, 

 Oregon. 



Allied to L. pallida, Adams, but is more delicate, more acute- 

 ly pointed, the aperture much larger, the lip expanded, and the 

 surface peculiarly decussated. The whorls are much more ob- 

 lique and less rounded than in L. desidiosa.
