384 TRANSACTIONS OF THE CANADIAN INSTITUTE. [Vou. VIII. 
Sagrina (virgula, &c.). Truncatulina culter. 
Polymorphina. Stilostomela rugosa. 
Nodosaria (arundinea, &c.). Ellipsoidina subnodosa. 
Cristelaria. Gaudryina pupoides. 
Biloculina depressa. Clavulina. 
Pulvinulina menardi. Pleurostomela. 
Rotalia soldanii. Planispirina celata, 
and a couple of ostracods. 
Mr. Earland remarks of this orbulina rock: “It is evidently a deep 
sea 00ze, a true globigerina ooze, and judging from the nature and con- 
dition of the shells, one laid down rapidly in tropical water of a depth of 
about 1,000-1,500 fathoms.” In another place Mr. Earland remarks, 
“]T have never seen any deposit containing such a high proportion of 
this species (orbulina).” Brady at page 611 of his “ Challenger” Report 
remarks that at certain points in the Atlantic orbulinae occur in enorm- 
ous numbers. The depths were 725 and 862 fathoms. 
The second of these deposits was a pteropod marl, possibly a 
continuation of that at Portantonio, which is only a few miles distant, 
and of which an account is given in the Geological Report on Jamaica, 
pages 67 and 313. After washing off the argillaceous and fine particles 
the residue is remarkable for the quantity of volcanic fragments and for 
the molluskan and foraminiferal fossils, which, though very brittle, arein a 
fine state of preservation. Unfortunately of this and the orbulina rock 
I only obtained small samples, not being aware when collecting them of 
the nature of the contents. From the Portantonio pteropod marl 
thirteen species of foraminifera were named in the geological report. 
From the Orange Bay sample I obtained the following : 
Miliolina seminulum. Clavulina cylindrica. 
Spiroloculina arenaria, parisiensis. 
limbata. Bigenerina penatula. 
Masilina alveoliniformis. Textularia aglutinans. 
Biloculina depressa. Textularia turis. 
elongata v. serata. concava. 
comata. Bulimina pyrula. 
Cornuspira foliacea. inflata. 
involvens. Casidulina crasa. 
Peneroplis pertusus. bradyi. 
Frondicularia inzequalis. Nodosaria communis. 
Cristelaria aculeata. hispida.
