FOEAMINIFEEA OF THE KEEIMBA AECHIPELAGO. 645 



in which it extends over the greater portion of the shell. As a rule, the short type is 

 more strongly marked than the long. 



Dimorphous individuals similar to the one figured by Millett occur at Stns. 7 and 

 12 and, as in his figure, this particular variety is characterized by the punctation 

 being arranged in longitudinal rows. The normal specimens, on the other hand, are, 

 as a rule, irregularly punctate, although a few of them show a tendency to a longi- 

 tudinal arrangement of the punctae in the later chambers.
