FOSSIL FORAMINIFERA FROM THE WEST INDIES. 31 



This is one of the most conspicuous and commonest of the Foram- 

 inifera of the Bowden marl. It was recorded by Jones and Parker as 

 Lituolasoldanii Parker and Jones, and it is in Hill's list as Haplostiche 

 soldanii (Parker and Jones). 



The variety differs from the typical form of the species in its much 

 more distinct chambers, more elongate tapering form, and in the 

 curious tendency to a bending of the axis toward the apertural end. 



Vanden Broeck described this variety from recent material dredged 

 in 84 fathoms off the Barbados. I have seen some of these specimens 

 and they are apparently identical with those from Bowden. 



Haddonia minor Chapman. 

 Haddonia minor Chapman, Journ. Linn. Soc, Zoology, vol. 28, p. 384, plate 36, figs. 1, 2, 1902. 



The following is a description of this species: 



Test attached at least by the earlier chambers, afterward growing erect or 

 in a vermiform manner; the earlier chambers often triserial, later ones variable; 

 wall roughened somewhat; aperture horseshoe-shaped. 



Length 2 to 4 mm. 



Two specimens from the Bowden marl seem very close to this species, 

 described by Chapman from Funafuti Atoll. This is not a surprising 

 distribution, as many things found in the Tertiary of the West Indies 

 are represented by allied forms now living in the Indo-Pacific. 



TEXTULARTIDiE. 



Textularia barrettii Jones and Parker.

Textularia barreltii Jones and Parker, Report Brit. Assoc, Newcastle Meeting, p. 80 and p. 

 105, 1863; Ann. Soc. Mai. Belg., vol. 11, p. 99, woodcut, 1876; Hill, Bull. Mus. 

 Comp. Zool., vol. 34, p. 147, 1899. 



The following is a description of this species : 



Test broadly conical, circular or somewhat compressed in end view, the 

 compression parallel to the line of union between the series of chambers, 

 exterior smoothly finished, wall of fine arenaceous material with a grayish 

 cement, sutures fairly distinct but not depressed, apertural end with the line 

 between the last-formed chambers depressed, trough-like, nearly straight, 

 the central third slightly excavated at the aperture, which is long and low; 

 interior of the aperture often denticulate, showing slightly at the surface; 

 chambers labyrinthic within, the divisions radially arranged in transverse 

 section. 



Length of fossil specimens up to 3 mm. 



This species is recorded from Bowden by Jones and Parker and by 

 Hill. It is rather a common and conspicuous species, but as far as I 

 have seen does not reach the dimensions of recent specimens from the 

 same general region. 



In Hill's list of species identified by Dr. R. M. Bagg is Textularia 

 trochus d'Orbigny. I have failed to find specimens of this species,
