PLATE XVI. 



1, SlGAJRETUS?^ DkEWI, EL.Sp. PI. XYI, Fig. I. 



Shell large, siibglobose, omamented with close, delicate, slightly 

 tindulating spiral lines, a somewhat stronger riblet at irregular 

 distances ; whorls 5, spire small, the whorls slightly rounded, first 

 two polished, body-whorl large and rounded ; aperture ovate, a little 

 produced anteriorly ; columella slightly curved, callous and reflected, 

 almost concealing the narrow chink-like umbilictis, outer lip thin. 

 Length 39, breaclth 34 mm. 



Form and Loc, — Pliocene, sand and blue clay : "Wanganui (Drew). 



Type. — Wanganui Museum. 



This species difEer's from *S'. undulatus, Hutton,^ in its larger size, 

 stouter shell, and less anteriorly produced aperture ; in sculpture 

 they are much alike. I name the species after my friend Mr. S. H. 

 Drew, Hon. Curator, Public Museum, Wanganui, who, by systematic 

 collecting, has added much to our knowledge of the Pliocene fossils 

 of this district. 



2. Ciesojtella? Neozelanica, n.sp. PI. XYI, Pigs. 2-6. 



Shell small, ovate, perforate, periostracum very thin, horny- 

 fuscous ; whorls 5, smooth, spire small, with the apex slightly eroded, 

 the whorls somewhat rounded, the last about thi'ee-fourths of the total 

 length and rounded, under an inch objective it is seen to be finely 

 striate with growth - lines ; sutures well marked ; aperture ovate, 

 somewhat oblique, columella thickened and slightly reflected, outer 

 lip thin and simple ; a callus extends from the insertion of the outer 

 lip to the columella, partially concealing the narrow umbilicus; 

 operculum horny, consisting of about two rapidly increasing whorls. 

 Length 2'lh, breadth 2*3 mm. 



[In attributing this shell to the genus Signretus the author has evidently followed 

 Hutton, and owing to the impossibility of communicating with him in time for 

 publication we have left it so, merely adding a ' ?,' but it is evidently nearer 

 to Ampullina. — Kd. Malac. Soc]
