ART. 6 FORAMINIFEKA: POLYMORPHINIDAE — CUSHMAN AND OZAWA 39 

 GUTTULINA JARVISI Cushman and Ozawa, new species 



Plate 7, figures 4, 5 



Test ovate, greatest breadth near the middle, broadly rounded 

 at the base, more or less acute at the apertural end; chambers inflated, 

 twice as long as wide, not much embracing, arranged in a clockwise, 

 quinqueloculine series, each succeeding chamber removed regularly 

 from the base giving a rounded appearance at the base; sutures de- 

 pressed, distinct; wall smooth, thick; aperture radiate. 



Length 0.90-1.80 mm.; breadth 0.80-1.50 mm.; thickness 0.50- 

 1.00 mm. 



Holotype. — (Cushman Coll. No. 11226.) From Tertiary, lower marl, 

 Cipero section, Trinidad. 



The present species is generally very large, attaining to nearly 2 

 millimeters in length. In its general appearance, it has an intermediate 

 character between Guttulina problema and Guttulina hantkeni. From 

 the former it differs in its rather broad base and much obliquely added 

 chambers, and from the latter in its more or less elongate chambers, 

 of which each succeeding one is not much removed from the base. 



Distribution. — Several specimens were found in the Tertiary 

 material from Trinidad, collected by P. W. Jarvis. They are from 

 the Eocene of the Cipero section and also from the "Uvigerina bed" 

 and the ''upper marl" of the same part of the island. We have a 

 single specimen from Albatross D5318 off the Philippines which is 

 very close to this species from Trinidad. 



GUTTULINA LEHNERI Cushman and Ozawa, new species 



Plate 8, figures 1, 2 



Test ovate to clavate, broadest in the lower half, broadly rounded 

 at the base, tapering to the apertural end; chambers elongated, 

 embracing, arranged in a regular, quinqueloculine series; sutures not 

 depressed, not very distinct; wall smooth, thick, often with fistulose 

 tubes at the apertural portion; aperture radiate. 



Length 0.65-1.35 mm.; breadth 0.38-0.55 mm.; thickness 0.25- 

 0.36 mm. 



Holotype. — (Cushman Coll. No. 10436.) From Tertiary, lower marl, 

 south end of Hospital Hill, San Fernando, British West Indies. 



Guttulina lehneri resembles Guttulina problema in general character, 

 but it has elongated but not inflated chambers and nondepressed 

 sutures, therefore its surface is quite even, and at a glance it can 

 be easily separated from other Guttulinas. It is approaching Glo- 

 bulina, but the chambers are arranged in a regular quinqueloculine 

 series. 



Distribution. — Rather common in the Tertiary of Trinidad. It 

 occurs in the "lower marl" of the Cipero section and also in the 

 "Sagrina beds" of Oropouche Lagoon, Trinidad.
