OP CONCFIOLOGY. 195 



obliquely expanded, callous within, tuberculated about the 

 middle ; columella but slightly callous and but little expanded. 

 Dark chestnut color, with an indistinct yellowish band, some- 

 times striped longitudinally, rarely wholly yellowish ; lip 

 stained with purple. 



Observations. — A terrestrial species. 



4. Paetula citeina, Pse. 



Description. — T. pyramidato-oblonga, solida, nitida, angusto 

 umbilicata; anfr. 5, convexis, sutura marginata; apertura 

 oblongo-ovalis, verticalis; labro planulatim obliquo, medio 

 versus tuberculatim calloso ; columella superne callosa. Fla- 

 vicante, obscure longitudinaliter strigata. 



Dimensions. — Long. 25, diam. 12 mill. 



Shell pyramidally oblong, solid, shining, closely umbilicate ; 

 whorls 5, convex, suture marginated ; aperture oblong-oval, 

 vertical; lip flatly oblique, tuberculately callous a short clis- 

 tauce above the middle; columella callously thickened above. 

 Citron or yellowish horn color, faintly striped longitudinally. 



Observations. — The two last-described species have been re- 

 ferred by Mr. Cuming to faba, Martyn. The former of the 

 above is quite distinct, both as to animal and shell. The 

 latter we may eventually class as a var. of faba, which is a 

 very interesting species, passing around the whole island of 

 Kaiatea near the shores, and hybridizing with the species up 

 the valleys, or throwing off varieties up the several valleys. 



5. Paetula teilineata, Pse. 



Description. — T. elongato-ovata, solida, umbilicata, longi- 

 tudinaliter striis irregularis subrugata, sub lente transversim 

 striata ; anfr. 4§, piano convexis, sutura subimpressa ; apertura 

 subrotunde ovata, vix obliqua, dentata, J longitudinis testae 

 subeequans ; labro rotundc incrassato ; columella superne no- 

 dose callosa. Flavicante, spira plerumque rufescente-fulva, 

 anfr. ultimo longitudinaliter castaneo strigato, fasciis tribus 

 intense castaneis cingulato, sutura albida marginata. 



Var. 1. Omnino intense castanea, longitudinaliter strigata, 

 sutura pallide marginata. 



Var. 2.- Omnino flavicante, longitudinaliter strigata. 



Shell elongate ovate, solid, umbilicate, somewhat roughened 

 longitudinally by coarse irregular stride, very finely striated 

 transversely; whorls 4|, flatly convex, suture somewhat im- 

 pressed; aperture rather roundly ovate, slightly oblique, den- 

 tate, less than one-half the length of the shell ; lip broadly and 

 roundly thickened; columella nodosely callous above. Cream
