196 B. J. L. Guppy — Rock-borings, Trinidad. 



BuLiMiNA iNFLATA, Seguenza. 

 Textularia sagittula, Defrance. (PL IX, Fig. 6.) 

 Length 1-0 mm. Fairly abundant in some samples. 



Textularia gramen, Orb. (PI. IX, Fig. 18.) 

 Length l"Omm. 



Textularia carinata, Hantk. (PL IX, Fig. 7.) 

 Length I'o mm. 



Textularia trochus, Orb. (PL IX, Fig. 8.) 

 Diameter 1-0 mm., height 1*5 mm. I take T. tnrris and T. Bareti 

 to be mei'ely varietal forms of this species. 



Textularia aspera, Brady. (PL IX, Fig. 17.) 



Only three examples were found, of which one (much the largest) 

 measured 3 mm. in length. 



NoDOSARiA RAPHANiSTRUM, Liun. (PL IX, Fig. 9.) 



The form found here is identical with N. bacillum, Defr., as found 

 in the Yieuna Basin and elsewhere. The synonymy of the species 

 includes raphanus, Zippei, badenensis, acuta, and many others. It is 

 probably not distinct from N. obliqua, the larger and more strongly 

 ribbed forms being found in shallow water, while the smaller, more 

 delicately costate forms come from deeper water. JV. raphanistrum 

 is not found in the oceanic beds. The longest specimen from the 

 Sangregrande boring is 5*5 mm. in length ; it is broken. Some 

 smaller examples are perfect. 



NoDOSARiA obliqua, Linn. (PL IX, Fig. 10.) 



The form found in the Sangregrande boring is N. vertebralis, 

 Batsch, which is only one of the many names conferred upon more 

 or less distinct varieties of this species. The length of our longest 

 specimen is 3*5 mm. 



Nodosaria soluta, Iteuss. (PL IX, Fig. 11.) 



Our specimens are generally of the curved variety, with little or 

 no constriction between the segments except perhaps one or two of 

 the later ones. It is exactly the same as N. elegans of the Vienna 

 Basin. The examples are usually about 2-3 mm. long. 



Cristellaria rotulata. Lam. (PL IX, Fig. 12.) 



Under this I include C. calcar and C. cultrata, as tbe forms found 

 here are somewhat intermediate. It is mostly small, the largest 

 being 2 mm. in diameter. 



Cristellaria aculeata, Orb. (PI. IX, Fig. 13.) 



Similar to the Pointapier specimens, except that the last whorl is 

 seldom so much produced. Longest diameter 2 mm. 



UviGERiNA (Sagrina) RAPHANUS, Parker & Jones. (PL IX, Fig. 14.) 



The specimens are about l"3mm. in length. The species is very 



abundant at all depths in the Sangregrande boring. It is the short
