ART. 6 FORAMINIFERA: POLYMORPHINIDAE — CUSHMAN AND OZAWA 41 

 GUTTULINA BAILEYI Cushman and Ozawa, new species 



Plate 9, figures 1, 2 



Test large, ovate, broadly rounded at the base; chambers elongated, 

 especially the later ones, numerous, not much embracing, arranged 

 in a quinqueloculine series, each succeeding chamber removed farther 

 from the base in the early stage, but little in the later stage; sutures 

 depressed, but not very distinct; wall thick, smooth; aperture radiate. 



Length 1.15-1.55 mm.; breadth 0.70-0.80 mm.; thickness 0.50- 

 0.60 mm. 



Holotype.— (Cat. No. 20951, U.S.N.M.) From Albatross D2416, lat. 

 31° 26' N., long. 79° 07' W., in 276 fathoms off the southeastern 

 coast of the United States. 



The present species is one of the largest among our collection of Poly- 

 morphinidae. Its early stage is just the same as GuUulina problema, 

 but it has more numerous chambers, and the later chambers are much 

 elongated and often added in a spiral series. It may be interesting 

 to compare the present species with Sigmomorpha crassa, which is very 

 large and in its early stage resembles GuUulina problema, but later the 

 chambers are more or less shortened and added in a sigmoid series 

 instead of a quinqueloculine series as in the present species. It is 

 named for Prof. J. W. Bailey, one of the early American workers on 

 the foraminifera. 



Distribution. — Besides the type locality, we have material very 

 similar from Albatross D5151, 24 fathoms, Tawi Tawi Group, 

 Philippines.
