 Abteil Syst., vol. 24, 1907, p. 39, pi. 2, fig. 16. 



Description. — Test free or attached, composed of the usual early 

 planospiral chambers, after which the chambers become irregularly 

 planospiral or highly irregular; wall porcellanous and imperforate; 

 aperture one or several, rounded, irregularly placed, sutures in later 

 chambers often indistinct. 



Distribution. — Rhumbler records this species from Laysan. A fig- 

 ure after Rhumbler is here given (pi. 8, fig. 6). While the speci- 

 mens are attached chambers are built with no calcareous floor, but 

 as soon as they become free complete chambers are built and a 

 secondary calcareous growth covers the remainder of the previously 

 attached portion of the test.

No. 5, 1904, p. 3.— Rhumbler, Zool. Jahrb., Abteil Syst., vol. 24, 1907, p. 40, 



pi. 2, figs. 17-19. 



Description. — "Test consisting of a few, misshapen, inflated seg- 

 ments, irregularly combined; aperture either single and simple, or 

 more usually, consisting of a number of rounded orifices variously 

 placed. 



"Diameter, one-thirtieth inch (0.84 mm.) more or less." 

 Distribution. — The first of the localities mentioned for this species 

 by Brady is off Honolulu coral reefs, Hawaiian Islands, in 40 fath- 

 oms. Rhumbler has the species from shore sands from Laysan. The 

 description is from Brady, and the figures from Brady and Rhum- 

 bler. 



Subfamily 3. QUIN-QUELOCULININ'.A.E. 



Test in the adult or in the early development of the test, at least 

 in the microspheric form with the chambers a half coil in length and 

 added in planes 144° from one another, five planes being necessary 

 to complete a cycle before a new chamber is added directly above one 

 of the previous ones, aperture at this stage at least alternately at 

 opposite poles of the test.
