Zoology, vol. 9, p. 162, pi. 5, figs. 12 a-c, 1884. 

 Test nearly as broad as long; chambers distinct; sutures slightly 

 depressed; chambers generally triangular in transverse section, the 

 angles subacute but not carinate; wall smooth and polished; aper- 

 tural end of the chamber very slightly expended, forming an ellip- 

 tical neck without a definite lip, but with a narrow elongate tooth. 

 Maximum length, 1 mm. ; breadth, 0.8 mm. ; thickness, 0.5 mm. 



This is a very widely distributed species occurring most commonly 

 in tropical waters, although there are numerous records for it in 

 comparatively deep water. Our specimens, in addition to the Alba- 

 tross stations, data for which are given in the accompanying table, 

 are from off Fiji Islands, 40 to 50 fathoms; off Nairai, Fiji, 12 

 to 24 fathoms; off Levuka, Fiji, 12 fathoms; and Viva Anchorage, 

 Fiji, 3 fathoms. The species is common also at Vavau Anchorage, 

 Tonga Islands, in 18 fathoms.
