154 MAJOR OWElSr OT^ THE SUBFACE-PAUNA OF MID-OCEAN. 



G. lulloides Nos. 2 and 3, G. (OrluUna) universa, and G. injlata 

 were in abundance, with one or two specimens of P. Menardii. 

 P. canariensis was moderately plentiful, P. crassa was present, 

 and I here observed some three or four individuals of G. (Orhu- 

 lina) universa. 



In lat. 28° S., long. 7° E., the number of Foraminifera found 

 on the surface had arrived at its maximum. G. injlata was the 

 principal form ; G. iuUoides Nos. 1 and 2, P. canariensis, and 

 P. Micheliniana plentiful; a few of G. (OrhuUna) tmiversa, and 

 one or two of P. Menardii were also found. 



In lat. 27° S., long. 5° E., G. {OrhuUna) universa became more 

 common, and many of them were less round in their form. G. 

 hulloides ISTo. 2 and G. injlata plentiful, but G. hulloides No. 1 

 not quite so abundant as before ; a trace of P. Micheliniana still 

 met with. 



In lat. 25° S., long. 3°E., the net was towing from four in 

 the afternoon till daylight next morning, and showed that but 

 very few Foraminifera were on the surface ; there were more of 

 G. hulloides No. 2 than other forms ; G. injlata was entirely 

 absent. P. Menardii was here represented more fully than 

 hitherto, and by one very large specimen. Although the Fora- 

 minifera were scarce here, other forms of animal life usually met 

 with at the same time of day were abundant. 



In lat. 23° S., long. 2° E., the Foraminifera were equally abun- 

 dant. P. Menardii were fine and plentiful ; G. hulloides Nos. 1 

 and 2, P. Micheliniana, and P. canariensis were all present, toge- 

 ther with several of G. (OrhuUna) tmiversa. 



In lat. 22° S., long. 1° E., P. Menardii is found very large, and 

 appears to be the principal form present, it seeming to have sup- 

 planted many of the others, with the exception of G. hulloides 

 No. 2. G. hulloides No. 1 shows two or three specimens also ; 

 there was one of G. (OrhuUna) tmiversa', G. injlata not quite 

 absent. 



In lat. 21° S., long. 1° W., P. Menardii and G. hulloides No. 2 

 continue plentiful as before ; G. (OrhuUna) universa, P. Micheli- 

 niana, and G. injlata but show their presence : at this point the 

 abundance of the Foraminifera appeared to end. It was during 

 the end of April that I sailed over this portion of the ocean. 



In lat. 18° S., long. 2° "W., very few Foraminifera were met 

 with — some dozen individuals of G. hulloides No. 2, three of P. 

 Menardii, and one of G. ( OrhuUna) tmiversa. 



In lat. 15° S., long. 5° "W., the same scarcity remained : one
