4. Glandina ^quatoria, n.sp. PL VII, Fig. 4. 



Testa fusiforme-oblonga, crassiuscula, nitida, purpurascente-castanea ; 

 anfractus 6, convexiusculi, longitudinaliter creberrime plicato-striati, 

 sub lente minute transversiui striati, ad suturas tenuiter crenulati ; 

 columella recta, abrupte truncata ; apertura cinerasceate-castanea, 

 peritremate alba instructa. Long. 59, diam. 27 mm. ; apertura 

 long. aO, lat. 12 mm. 



Hah. — Peramba, Ecuador. 



Tbe single specimen of tbis sbell recently received from Ecuador 

 appears to differ from any hitherto described species. Although 

 closely allied to O. saccata, Pfr., it is darker in colour, smaller, and 

 much thicker, the longitudinal plication is closer, and the transverse 

 striation much finer ; it has also a straighter columella. 



5. Cyclophorus Underwoodi, n.sp. PL VII, Figs. 5-8. 



Testa profunde et aperte umbilicata, conico - depressa, solidula, 

 superne ustulato-castanea, inferne viridescenti-lutea, sub periostraco 

 fusco - corneo deciduo alba, ad peripheriam saturate fasciata ; an- 

 fractus 6, convexi, spiraliter undato-corrugati, infra laeves ; apertura 

 oblique circularis, peristomate simplice, ad suturam sinuato ; operculum 

 corneum, arctispiratum, conspicue lamellosum. Diam. maj. 45, min. 

 32 mm. ; alt. 30 mm. 



Hah. — Carrillo, Costa Pica. 



This shell, recently discovered by Mr. Underwood at Carrillo, Costa 

 Pica, is a fine example of an occidental Cyclophorus. It presents 

 a peculiarity in the construction of the operculum, the margin of 

 which is marked by exceptionally strong and extended lamella?, 

 a consequence, probably, of the extreme obliquity of the aperture. It 

 may also be observed that the sutures of the two last whorls appear 

 canaliculated ; whether this feature is constant or not, cannot be 

 positively assumed in the absence of a full series of specimens.
