Test free, very much compressed, broad and triangular in front view, 

 the apertural end usually broadly convex, in end view narrow, widest 

 near the middle, thence tapering toward the rather acute lateral mar- 

 gins; chambers broad and low in the adult, in two alternating series, 

 somewhat curved; sutures thickened, in the later portion usually 

 somewhat sigmoid, median line with a slightly raised median suture;

This is one of the typical Indo-Pacific species especially in the warm 

 shallow waters of coral reefs. There are numerous records for the 

 Indo-Pacific as follows: Shore sand, Melbourne (Parker and Jones); 

 Mauritius, rare, from the intestine of Maretia planulata (Moebius) ; 

 off East Moncoeur Island, Bass Strait, 38 fathoms; off Raine Island, 

 Torres Strait, 155 fathoms; off Kandavu, Fiji, 255 fathoms; off Levuka, 

 Fiji; Nares Harbor, Admiralty Islands, 17 fathoms; Honolulu coral 

 reefs, 40 fathoms (H. B. Brady) ; Mauritius and East Australia (Egger) ; 

 from the lagoon at Funafuti; shore sands of Victoria (Chapman); 

 shallow water off Laysan Island (Rhumbler) ; off the Hawaiian 

 Islands, 305 fathoms (Bagg), 249 and 271 fathoms (Cushman); a 

 single specimen from the Kerimba Archipelago, 5-10 fathoms (Heron- 

 Allen and Earland) ; Lord Howe Island (Heron-Allen and Earland) ; a 

 single specimen, Philippines; and Hawaii to Midway Island (Cush-
