NO. 1 CUSHMAN', MCCULLOCH : ARENACEOUS FORAMINIFERA 93 



This species differs from G. arenata Galloway and Wissler in the 

 more flattened and more flaring test, lower and more numerous cham- 

 bers, very small proportion of triserial chambers and smoother surface. 



The species varies in its relative length and breadth as shown by 

 our figures. It also occurs at the following localities: 2005, 2065, 2010, 

 2009, 2006, 2064, 2063, 230, 232. 



Distribution. — Type locality, off the coast of California at Arvila 

 Pier in 7 fms. In 10 fms. Cuyler Harbor, San Miguel Island, and south- 

 ward in 180 fms. off Inner Gorda Banks, Mexico. 



Gaudryina subglabrata Cushman and McCulloch, new species, var. 



Plate 8, Fig. 8 



The figured specimen shows an extreme form in which the periphery 

 is carinate and the chambers somewhat higher than in the typical form. 

 The figured specimen is from locality 239 and there are other somewhat 

 intermediate forms from localities 241 and 2000. 



Distribution. — Type locality, off Fraile Bay in 80 fms. and off Cape 

 San Lucas, Mexico, in ?)3 to 133 fms.

 sutures distinct throughout; wall coarsely arenaceous, of angular sand 

 grains with a large proportion of whitish cement, surface rather
