Test slightly longer than broad, triangular in transverse section; 

 wall ornamented with numerous, slightly elliptical pits evenly dis- 

 tributed over the surface of the test, forming a definite pattern. This 

 is a distinctive Indo-Pacific species so far as the records show. It is 

 already known from the following localities: Off Ascension Island, 

 7 fathoms ; off Calpentyn, Ceylon, 2 fathoms ; shore sands, Tamatave, 

 Madagascar; Port Elizabeth, Algoa Bay (H. B. Brady) ; Malay 

 Archipelago, rare (Millett) ; Funafuti (Chapman) ; Kerimba Archi- 

 pelago; Cebu in 45 to 120 fathoms; and Lord Howe Island (Heron- 

 Allen and Earland); Binang Pool, Subin Bay; Tara Island; Sulu 

 region off Jolo, off Tawi Tawi, near Basilan, China Sea, off southern 

 Luzon, and between Burias and Luzon, also Murray Island, Aus- 

 tralia (Cushman). Our only material of this species, which is very 

 typical, is from Makemo Lagoon.
