MAJOE 0"WEN ON THE SUKrACE-rAUNA OF MID-OCEAN, 155 



specimen of G. huUoides No. 1 was found, with a few of G. lul- 

 loides No. 2 and G. (^Orbulind) universa. 



In lat. 15° S., long. 6°^., the same scarcity; this continued 

 at lat. 13° S., long. 8° W. 



In lat. 12° S., long. 10° "W., the number of Foraminifera very 

 slightly increased to a few of G. hulloides No. 2, two Orhulince, 

 and one P. Menardii. 



In lat. 11° S., long. 10° W., a very slight increase took place. 



In lat, 3° S., long. 18° "W., the Foraminifera again became 

 abundant — G. lulloides No. 2 and P. Menardii being equally 

 fine and plentiful, with a trace of G. {Orbulina) universa and G. 

 inflata -. this was in the night of the 12th of May. 



In lat. 2° S., long. 19° W., the Foraminifera had again nearly 

 disappeared; still there were a few of G. hulloides No. 2, but 

 m.ore o£ P. Menardii. 



In lat, 1° S., long. 21° W., but a trace remained of the same 

 forms. 



In lat. 0°, long. 22° W., G. hulloides No. 2 became more 

 plentiful, with traces of G. inflata, G. hiolloides No. 1, and P. 

 Menardii. 



In lat. 2° N., long. 23° W., there were about the same number 

 of the Foraminifera as before, consisting of G. hulloides No. 2 

 and P, Menardii, but the latter was here the more abundant of 

 the two forms. 



In lat. 3° N., long. 24° W., the same observations may be ap- 

 plied to this part. 



In lat. 6° N., long. 26° "W., no Foraminifera on the surface. 



In lat. 7° N., long. 26° W., a very few of G. hulloides No. 2, 

 with traces of G. hulloides No. 1, and G. inflata. 



A few miles to the north-west of the last spot, G. hulloides 

 No. 2 and G. inflata suddenly became more plentiful, and 

 amongst them I noticed two specimens of P. Menardii and one 

 of G. (Orhulina) universa. 



In lat. 9° N., long. 28° W., the Foraminifera were met with in 

 great abundance : they consisted of G. hulloides No. 2 and G. in- 

 flata, together with a fair supply of G. (OrhuUna) universa and a 

 trace of P. Menardii. 



In lat. 10° N., long. 29° "W., the Foraminifera were in as great 

 profusion as I have ever met with them. G. hulloides No. 1 

 and G. inflata were the principal forms ; but P. Menardii and G. 

 (^OrhuUna) universa were well represented, and of G. hulloides 

 No, 1 there were many individuals.
