There is a single specimen whicli is undoubtedly the same species 

 which I described from the Philippines. This specimen is not as 

 large as the type: it is between 3 and 4 mm. in length, and 1.2 mm. in 

 width. This is another species which connects the foraminifere fauna 

 of the Philippine region with that of New Zealand and Australia.

A few specimens with the characteristic apertural characters 

 occur. They are close to the specimens figured by Brady,^ but with 

 the keel much more prcgiounced. In the general form of the cham- 

 bers and keel they are somewhat similar to the figm*e of C. nitida 

 as figured by Brady,^ except in the apertural characters. 



There is one specimen mounted on a separate slide from the others, 

 which is one of the wild-growing forms mentioned and figured by 

 Brady and is very similar to Cliallenger.^ Sidebottom * had one 

 specimen of this same form. From a comparison of the Challenger 

 figures with the typical m-aterial, it is difficult to see what the two 

 forms have in common. Our specimen is certainly like Brady's fig- 

 ure referred to, but is very unlike the typical specimens found in 

 this same material.
