KORAMINIFERA OF THE ATLANTIC OCEAN.

dant." The other records are south of Australia, 2,600 fathoms 



(4.755 meters); north of New Guinea, 1,070 fathoms (3,109 meters), 



and south of Japan, 315 fathoms (631 meters); '"but the specimens 



from these [last three] localities are of poor dimensions and few in 



number." Flint records it from two Albatross stations D2377 in the 



Gulf of Mexico in 210 fathoms (384 meters) [ ?] and D256S ofl' Martlias 



VineAard in 1,7S1 fathoms (3.257 meters). I have had the species 



from nine Albatross stations all but one of them south and west of 



the Geor>j:es Banks at depths rant^inj)^ from 1,362 to 2,369 fathoms 



(2,491 to 3.332 niettM-s). There is a later Cluillenr/er reconl from this 



same region, station 44 in 1,700 fathoms (3,109 meters). The otlier 



station is from the Gulf of Mexico in 27 fathoms. In examining the 



material in Dr. Flint's collection I find a slide with specimens from 



D2377 and D2568, the whole marked Uaplojpliragmium foUaceum. 



There are numerous specimens of both Ammobacvlites foliaceus and ^. 



tenurmargo and as I have found .1. tenuimarqo at this station and not 



A. foliaceus I am inclined to think that Doctor Flint's record for 



A. foliaceus from D2377 should be changed to A. tenuimargo. Both 



species are however found in the Gulf of Mexico. 



A. foliaceus is a very well defined species easily distinguished and 

 it seems odd that it is not more often recorded if it has the wide dis- 

 tribution that Brady's other records seem to indicate. An exami- 

 nation of the original Clwllenger material should show whether these 

 other -pecords are this species or whether this is really an Atlantic 

 species. It should be noted, however, that numerous species which 

 have their origin in the Indo-Pa!'ilic are found along the western 

 side of tlie Atlantic but not on the eastern side.
