36 GEOLOGY AND PALEONTOLOGY OF THE WEST INDIES. 



prominent, and little affected by the individual chambers, running uninter- 

 ruptedly from one end of the test to the other; specimens, when complete, 

 with a short spine at the initial end; aperture radiate, slightly produced. 

 Length up to 7.5 mm. 



This species is a common one in the Carribbean and Gulf of Mexico 

 at the present time and in the Pacific tropical regions as well. Its main 

 characteristics are the clear sutural areas between the chambers and 

 the slightly curved elongate test. Although by no means common, 

 well-developed specimens are found occasionally in the material from 

 Bowden. Jones and Parker record Nodosaria raphanistrum Linne* 

 from the Bowden marl, and probably this is the same as recorded here 

 as N. vertebralis. In HilPs list of species identified by Bagg no Nodo- 

 saria appears, but Vaginulina legumen (Linn6). Possibly this may 

 have been a specimen of N. vertebralis. Jones and Parker also record 

 single specimens referred to Dentalina acicula Lamarck and Vaginulina 

 striata d'Orbigny. Both of these and their N. raphanistrum are given 

 as 5.25 mm. in length, and it is a question if they are not perhaps all 

 N. vertebralis. In all the material I have examined the only Nodo- 

 sarian specimens I have seen may all be referred to N. vertebralis. 



Nodosaria species. 

 (Figure 2, a and 6.) 



In the sections 2 specimens of Nodosaria occur, one showing 3, the 

 other 4 chambers. They are small, of fairly uniform diameter, and 

 may represent a small, few-chambered species or may be the young of 

 some larger species, although if the latter the adults were not observed.

 mens of Nodosaria. Figure a, four-chambered specimen from station 

 7519, drift near top of landslide next north of Los Melones Mountain, 

 Cuba. Fig. 6, three-chambered specimen from station 7513, lime-

The stations are 7513, orbitoidal limestone, outcrop where Palmer 

 Trail joins Ocujal Trail and 7519, from drift near top of landslide next 

 north of Los Melones; both collected by 0. E. Meinzer.
