"This has kindly been compared by Dr. von Mollendorff, 

 who says that the species has some affinity with P. recondita 

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

 cylindrical in form" (Fulton). 



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



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

 conic, very delicately diagonally striatulate, slightly trans- 

 lucent, tawny-whitish, dirty, chalky. Spire couic-turbiuate, 

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

 Whorls G 1 /^, 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 lamella 1 of the interior. Length 3, 

 diam. 2!/4 mm.
