with a scalpel, and sections can be ground with little trouble. In Botelliiia the grains are 

 larger and so firmly cemented together as to resist dislodgment without fracture, and 

 sections are very hard to grind. Moreover, BotelUna, on the rare occasions when it has 

 been found perfect, exhibits a bulbous proloculum in strong contrast with Proiobotellina, 

 in which there is no increase in the diameter of the tube at the initial extremity. Sections 

 of the two organisms exhibit a strong contrast between the projecting spicules of 

 ProtoboteUina and the firmly built outgrowths which fill the tube of BotelUna with a 

 labyrinthine core. 



The affinities of ProtoboteUina are not very evident. While placing it at present near 

 BoteUina on account of general resemblances and its primitive labyrinthic interior, we 

 are not convinced that it lies in any direct relationship to that genus. The friable 

 nature of the shell wall would suggest a connection with Hyperammina but for the 

 absence of a bulbous proloculum, which is even more characteristic of that genus 

 than of BoteUina. 



P. cyUndrica is widely distributed over the sandy area between the Falkland Islands 

 and the coast of South America, but is probably never very abundant. We have perfect 

 specimens from a number of stations, depths ranging between 150 and 300 m., and 

 fragments from others. The size varies greatly at diff^erent stations, but on the whole 

 averages about 25 mm. in length and 4 mm. in diameter. A specimen from station 

 WS 243 was over zh in. long, and fragments have been seen which suggest even larger 

 dimensions. 



The finding of living specimens with other Foraminifera and Polyzoa attached to the 

 basal end indicates that the organism lies flat on the surface of the sandy bottom, and 

 does not assume an erect position or attach itself basally to other objects.
