N. B. — Mr. L. de Verteuil pointed out the junction beds to 

 me in November, 1894, and in February, 1895, I went over the 

 ground again with him and Prof. J. B. Harrison. 



PAPER No. 15. 

 NOTES ON A SPECIMEN OF GLOBIGERINA ROCK 

 FROM NAPA RIM A . 



Read before the Victoria Institute May 31, 1897 and pub- 

 lished in the "Proceedings," p. 172. 



This specimen given to me for examination by Professor J. 

 B. Harrison came from the neighborhood of the S. Madelein 

 Factory. It is a Globigerina Rock of blue-grey tinge containing 

 a large proportion of mud. It shows signs of brecciation. The 

 residue after washing contains a fair series of Foraminifera, but 

 none of fine development — sandy forms including Trochamina, 

 Clavulina, etc., are pretty abundant, and so is Gaudrina pupoides, 

 but I saw none full grown. Bigenerina is common but small. 



I am inclined to think that this was deposited in relatively 

 shallow water. 



APPENDIX. 



I give here the names of some additional species of 

 Foraminifera from the Microzoic Rocks of Naparima described 

 or determined since my paper on the subject was read to the 

 Field Naturalists' Club. 



Ellipsoidina ellipsoides, Seguenza 



" subnodosa, Guppy 



" exponens, Brady 



Stillostomella rugosa, Guppy 

 Frondicularia flabelliformis, Guppy 

 Gaudryina lobata, Guppy 



pariana, Guppy 

 Gonatosphaera prolata, Guppy 



The two latter are from the Ditrupabed of Pointapier.
