Test of medium size, much compressed, triangular, the outer aper- 

 tural end broadly convex; chambers numerous, 9 to 11 on each side 

 in the adult; sutures fairly distinct but only slightly depressed; 

 surface roughly formed, of sand grains so cemented as to leave a 

 characteristic, rough, somewhat flaky surface; aperture fairly large, 

 curved, at the base of the last-formed chamber, with a slight lip. 

 Length, 1 to 1.5 mm. 



This species is one of the commonest in the shallow water of the 

 general Indo-Pacific region. It is much compressed and has a char- 

 acteristic size and shape in the adult specimens. When seen with 

 other specimens in the sample it is usually much lighter in color. 

 It is evidently most at home in shallow water of coral-reef regions, 

 and while there are some records from deeper water they are mostly 

 small specimens that may have been easily carried into deeper water. 

 Previous records are by Heron- Allen and Earland from the Kerimba 

 Archipelago, from Timor Sea, Java, 50 fathoms. I have recorded it 

 from seven stations off the Philippines at depths ranging from 20 to 

 494 fathoms, and from shallow water about Samoa. In the present 

 collections it has occurred at the following localities: Mokaujar 

 Anchorage, Fiji; Viva Anchorage, Fiji, 3 fathoms; Levuka, Fiji, 12 

 fathoms; Nairai, Fiji, 12 fathoms and 24 fathoms; Vavau Anchorage, 

 Tonga Islands; Rongelap Atoll, Marshall Islands; and from the 

 Guam Anchorage, Ladrone (Marianas) Islands, 21 fathoms. At the 

 last locality specimens are abundant, and the largest in size of any 

 of the localities. 



TEXTULARIA FOLIACEA Heron-Allen and Earland OCEANICA, new variety 



Plate 1, Figures 11, 12 



Variety differing from the typical in the much thicker form and 

 rougher appearance of the test. Length of holotype of variety, 2 

 mm. ; width, 1.25 mm. ; thickness, 1 mm. 



Holotype of variety. — Cushman Coll. No. 14667, from Mokaujar 

 Anchorage, Fiji. 



This variety is much thicker than the typical, much rougher, and 

 usually of a much darker color. The two occur together at some of 

 the localities, but the variety seems to occur alone at certain others. 

 The holotype is an exceptionally large, fine specimen, much larger
