NO. 1 CUSHMAN, MCCULLOCH : ARENACEOUS FORAMINIFERA 95 



Rudigaudryina inepta Cushman and McCulloch, new species 

 Plate 9, Figs. 3-10 



Test in the earliest stages triserial, at least in the microspheric form, 

 followed by a series of biserial chambers increasing rather rapidly in 

 size and breadth, these in turn in the adult followed by a series of very 

 irregular chambers in a single series or variously placed, usually mak- 

 ing up the larger part of the test, later chambers inflated ; sutures ob- 

 lique, not depressed in the earlier portion, often deeply depressed in the 

 adult, irregular portion; wall finely arenaceous, with much cement, 

 smoothly finished ; aperture in the adult rounded with a slight neck. 



Length up to 1.00 mm. 



Holotype (AHF no. 15) from locality 433. 



This is a very peculiarly formed species as the figures will show. 

 It was at first thought this might be purely an abnormal form but no 

 normal specimens like the early stages were found in any numbers and 

 the form has occurred at numerous stations as follows: 418, 207, 447, 

 433, 227, 226, 82, 216, 414, 114, 553. 



Distribution. — Type locality, Tagus Cove, Albemarle Island, in 

 80-100 fms. ; off Catalina, off Guadalupe Island, Mexico, southward to 

 the Galapagos Islands.
