5- Glyphis nigriradiata Reeve. 



REEVE. Conch. Ie. Vol. VI, Fissurella, fig. 8l. 



Stat. 258. Tual-anchorage, Kei-islands. 22 M. Lithothamnion, saiid and coial. 1 Spec. 



Agreeing exactly with the figure and description of Reeve, except that the interrupted 

 character of the black rays is not conspicuous. Pilsbry thinks it may be the young of G. Rüppellii 

 Sow. (Man. of Conch. Vol. XII, p. 217) but this suggestion seems to be erroneous, as the orifice 

 in the present species is rounded-oval, in accordance with Reeve's figure, whereas in Rüppellii 

 it is "squarish-oblong". 



6. Glyphis sp. 



Stat. 98. 6° 9 N., i20°2i'E. 350 M. Sand. 1 Spec. 



A dead, much worn shell, too bad for identification or description, belongs to the genus 

 Glyphis and is certainly distinct from the preceding species. 



7. Glyphis corbicttla Sowerby ? 



SOWERBV. Thes. Conch. Fissurella, p. 200, fig. 180. 

 PILSBRY. Man. of Conch. Vol. XII, p. 220, PI. 61, fig. 20. 



Stat. 115. East side of Pajunga-island, Kwandang-bay. Reef. 1 Spec. 



Stat. 1 16. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. 1 Spec. 



Stat. 152. Wunoh-bay, N.W. coast of Waigeu-island. Reef. Lithothamnion-bottom. 1 Spec. 



Stat. 258. Tual-anchorage, Kei-islands. 22 M. Lithothamnion, sand and coral. 1 Spec. 



The specimens are small, probably young, and are very nearly allied to G. coróicula, 

 the slight differences may perhaps depend on age or on variability. The description in Sowerby's 

 Thesaurus, copied by Pilsbry, is very short and insufficiënt. The specimens under consideration 

 resemble also G. Townsendi Melv. (Mem. and Proc. of the Manchester Lit. and Phil. Society, 

 Vol. 41, p. 20, PI. 7, figs. 27, 2ja) but the shape of the shell and the position of the orifice 

 agree better with the fig-ures of G. corbicula. 



Puncturella Lowe. 



1. Pzmctur'clla gemmata n. sp. PI. VII, fig. 3. 



Stat. 280. 8°i7'.4S., i27°3o'.7E. 1224 M. 1 Spec. 



Shell elevated, conical, with oval base and curved apex. Front slope convex, posterior slope 

 concave, side slopes convex below, concave towards the apex, which is slightly bent towards the 

 left and shows scarcely one spiral whorl on the right side. Colour yellowish. Sculpture consisting 

 of numerous, radiating riblets, which are alternately stronger, the intermediate weaker ones don't 

 reach the summit but end at about ' : /., of the height, they are surmounted by rounded-triangular 

 or pear-shaped beads, the interstices are rather irregularly concentrically wrinkledi orifice oval, 

 lying just before the apex, slightly narrower above, its length is about 1 Mill., its breadth a 

 little more than l /,. Interior white, smooth ; septum large, nearly straight, only slightly curved,
