''This has kindly been compared by Dr. von M611endorff r 

 who says that the species has some affinity with P. rec&ndita 

 Tapp.-Can., from the Am Islands, but is smaller and more 

 cylindrical in form" (Fulton). 



93. GASTROCOPTA NEOCALEDONICA n. n. PL 24, fig. 14. 



Shell dextral, very minute, nearly covered rimate, ovate- 

 conic, very delicately diagonally striatulate, slightly trans- 

 lucent, tawny-whitish, dirty, chalky. Spire conic-turbinate, 

 the apex obtuse, pale buff, glossy; suture deeply impressed. 

 Whorls 6%, convex, regularly increasing, the last one-third 

 the total length. Aperture piriform, narrowed, quite broad 

 in the upper part, and obtusely angular at the base, toothed 

 and lamellate; peristome continuous, expanded, white; right 

 margin having a small tooth-like tubercle which is directed 

 towards the lower end of a strong parietal lamella a little 

 oblique to it; this lamella divides the aperture unequally, 

 and obstructs the entrance ; with the tooth of the right margin 

 it forms a sort of second aperture, which is round, a little 

 acute basally. The columella is thickened by a little sinuous 

 fold. The umbilicus is nearly closed by the base of the last 

 whorl, on the outer part of which there are two punctifonn 

 pits corresponding to lamellae of the interior. Length 3, 

 diam. 2*4 mm.
