FOSSIL FORAMINIFERA FROM THE WEST INDIES. 41 



Discorbis saulcii (d'Orbigny). 



Rosalina saulcii d'Orbigny, Foram. Amer. Merid., p. 42, plate 2, figs. 9 to 11, 1839. 

 Discorbina saulcii Parker and Jones, Quart. Journ. Geol. Soc., vol. 28, p. 156, 1872; H. B. 

 Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 653, plate 91, figs. 6 a to c, 1884. 



Most of the records for this species are from the Pacific. The 

 specimens from station 3461, marl, gorge of Yumuri River, Matanzas, 

 Cuba, collected by T. W. Vaughan, are very similar to the published 

 figures. 



Discorbis allomorphinoides (Reuss). 



Valvulina allomorphinoides Reuss, Sitz. Akad. Wiss. Wien, vol. 40, p. 223, plate 11, fig. 6, 1860. 

 Discorbina allomorphinoides H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 654, plate 

 91, figs. 5 and 8, 1884. 



Several specimens from the Bowden marl, Bowden, Jamaica, are 

 very close to Brady's figures, especially plate 91, figure 5 in the Chal- 

 lenger report, referred to above. Reuss's material was from the Creta- 

 ceous of Westphalia, and I am not at all satisfied that Brady was 

 justified in referring the recent specimens from Torres Strait and the 

 Philippines to Reuss's species. It seems more than likely that the Indo- 

 Pacific recent specimens and those from the Miocene of the West Indies 

 may be identical, as there are numerous other instances of West Indian 

 Miocene species persisting in the living fauna of the Indo-Pacific. 



Planorbulina retinaculata Parker and Jones. 



Planorbulina retinaculata Parker and Jones, Phil. Trans., vol. 155, p. 380, plate 19, fig. 2, 1865. 



A single specimen with irregularly placed chambers, very coarsely 

 perforate, and with the peripheral spinose character of the type figure, 

 was found at station 3461, marl from gorge of Yumuri River, Matanzas, 

 Cuba, collected by T. W. Vaughan. The type specimens were from the 



tropics. 



Truncatulina lobatula (Walker and Jacob). 



Truncatulina lobatula (Walker and Jacob), H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 

 9, p. 660, plate 92, fig. 10; plate 93, figs. 1, 4, 5, 1884. 



A single specimen was found in material from Bluff 3, Cercado de 

 Mao, Santo Domingo. The later chambers are somewhat irregular, 

 as is often the case in attached recent specimens. The species also 

 occurs in the Miocene of South Carolina and Virginia. 



Truncatulina haidingerii (d'Orbigny). 

 Rotalina haidingerii d'Orbigny, Foram. Foss. Bass. Tert. Vienne, p. 154, plate 8, figs. 7 to 9, 1846. 



A single specimen from Bluff 2, Cercado de Mao, Santo Domingo. 



Truncatulina praecincta (Karrer). 



Rotalia proedncta Karrer, Sitz. Akad. Wiss. Wien., vol. 58, p. 189, plate 5, fig. 7, 1868; 



Seguenza, Atti. Accad. Lincei, ser. 3, vol. 6, pp. 56, 64, 1897. 

 Truncatulina prcecincta H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 667, plate 95, 



figs. 1 to 3, 1884. 



The following is a description of this species : 



Test free, biconvex, dorsal side slightly, ventral side strongly, peripheral 

 margin bluntly rounded, chambers numerous, sutures on dorsal side oblique,
