vestibule, as in G. bulloidcs. In the fossil example, the aperture is 

 a narrow slit at the end of the last chamber, towards the central 

 depression of the under side of the test. Following Brady's 

 " Scheme of the genus Globigerina," the recent form must be 

 placed in group a with G. bulloidcs, &c. ; whilst Egger's fossil 

 G. dubia must find a place with G. Dutertrei in group B. 



In the Malay Archipelago, Brady's form is but little removed 

 from G. bulloides, and hardly deserves separate mention. Egger's 

 G. dubia scarcely differs from G. Dutertrei ; the plan of growth is 

 similar, and in the young specimens the aperture is large, becom- 

 ing more and more constricted in the adult stage until in the thick- 

 shelled mature examples it is reduced to a mere slit. 



It will be sufficient here to record that the four varieties are 

 represented in the Malay Archipelago, leaving the identity of 

 bulloides and Eggeri, and of dubia and Dutertrei, an open question.

 but occurs at several Stations in both Areas.
