FOEAMINIFERA OP THE KEEIMBA AECHIPELAGO. 641 



1 Station. 



One typical individual from Stn. 10. The species is very clearly distinguishable 

 from B. aciileata d'Orb. by the thickly-set investment of small and very fine spines 

 covering the surface of the chambers on the aboral half of the shell.

At Stn. ^X a single specimen was found, characterized by a somewhat compressed 

 mode of growth (as in Buliinina elegantissima, var. compressa) and by the presence of 

 coarse perforations between the costse, which are also noticeable as being continuous 

 over the entire surface of the chambers composing the cell. Another not very typical 

 specimen was observed at Stn. 2 h. 



B. infiata is normally a deep-water species, so that the presence of these individuals 

 in shallow water at Kerimba is striking.

This very beautiful little form is much rarer in the Kerimba area than is usually 

 the case in shallow-water tropical gatherings. The only Stn. where more than an 

 occasional specimen was found was Stn. 11, and even there it is of rare occurrence, 

 though quite typical and well developed. At Stn. 1 X one of the two individuals 

 observed had the whole of the face of the terminal chamber eroded away, suggesting 

 that this species may be addicted to the " association " habit or to the method of 

 reproduction of which we believe this feature to be significant.
