46 BULLETIN J04, UNITED STATES NATIONAL MUSEUM. 



The following extracts are taken from descriptions by earlier 

 authors : 



Test consisting of several independent arenaceous chambers, iudlA'idually spher- 

 ical or subspherical in shape and of nearly even size, attached to each other by their 

 outer surfaces, but without stoloniferous intercommunication, each chamber having 

 its own external aperture. Spheres seldom more than six or eight in number, and 

 usually arranged with more or less regularity. Texture finely sandy, nearly smooth 

 externally. Diameter of the individual chambers, one-thirtieth of an inch (0.8 mm.) 

 or less. — (H. B. Brady.) 



Free or adherent, subglobular; surface coarse and rough; walls thin, composed of 

 rather coarse sand mixed Avith sponge spicules; color a rich reddish brown; orifices 

 one or several, at the end of long slender tubes. Generally united into colonies, 

 either in straight series, or curved, or confused, connected by stoloniferous tubes. 

 Diameter of individual tests, 0.4 to 0.8 mm. (one-sixtieth to one-thirtieth inch). — 

 (Flint.) 



Distribution. — The records for this species are very few. North 

 Atlantic, south of Rockall Bank, 1,263 fathoms (Brady); Faroe 

 Channel (Pearcey); off Bahia, Brazil (FUnt); Antarctic (Pearcey); 

 North Pacific (Brady). 



I have seen material only from Albatross D2760, off Bahia, Brazil, 

 1,019 fathoms, the stations recorded by Fhnt for S. consociata 

 (U.S.N.M. No. 9860). 



Both descriptions are given, that of S. socialis H. B. Brady and S. 

 consociata Flint. The two agree very closely except in the matter 

 of stoloniferous connections, wliich do not appear to be definite in 

 the material I have seen. Therefore I have brought the two to- 

 gether, although larger series of material may show real differences.

 Saccammina minuta Rhumbler, Foram. Plankton-Exped., pt. 1, 1911, pi. 1, 

 figs. 8, 9; pt. 2, 1913, p. 375. 



Description. — Test free or fixed, generally spherical, when fixed 

 the lower side flattened, aperture often represented by a short tube 

 coming out between the sand grains, usually inconspicuous. 



Diameter, 0.18-0.42 mm. 



Distribution. — Rhumbler records this species from the Plankton- 

 Expedition stations, off the Hebrides, in 2,275 meters, and near St. 

 Vincent, 4,980 meters.
