116 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 



The results of studies on the extensive collections of the Allan Han- 

 cock Pacific Expeditions in other fields are pointing in the same general 

 direction, particularly with reference to new species. The results so far 

 indicate that the majority of new species is to be expected in the Gulf 

 of California and in the vicinity of the Galapagos Islands. T. astutia is 

 restricted to the waters of the Gulf of California. T. orbica, T. lauta, 

 T. ramosa, and T. vola have been found only in the vicinity of the 

 Galapagos Islands. 



Since there is a possibility of collecting more material from year to 

 year, a certain amount of material containing new species has been set 

 aside for the time being to avoid later difficulties. 



The holotypes and paratypes of the new species described in this 

 report are a part of the collections of the Allan Hancock Foundation, 

 The University of Southern California, Los Angeles. Paratypes are to 

 be deposited in the U. S. National Museum, Washington, D.C., and 

 in the Cushman Laboratoiy for Foraminiferal Research, Sharon, Mass.

Test very short, subrhomboidal in front view, almost as thick as 

 wide, periphery subacute to rounded; chambers numerous, increasing 

 very rapidly in height as added, wider than high, inflated slightly; sutures 

 distinct, depressed, nearly straight, but curving downward slightly near 

 peripheral margin, much oblique ; wall coarsely arenaceous with a moder- 

 ate amount of cement, smoothly finished; aperture a broad low slit at 

 the inner margin of the last-formed chamber. Length, up to 1.00 mm.; 

 greatest width, 1.00 mm.; thickness, about 0.85 mm. 



This species has been noted from the Miocene of central Europe, the 

 Pliocene of Italy, and many localities in the present oceans. It has been
