appear to be in the microspheric, and the shorter in the megalo- 

 spheric condition. 



Another set is of the same variety as that figured by Heron- 

 Allen and Earland in the above reference, having the roughened, 

 granular deposit in the neighbourhood of the sutures referred to by 

 them. 



There are also two large tests which appear to be intermediate 

 between B. textilarioides and V. texturata Brady. I have illus- 

 trated one of these (fig. 19). 



Bolivina punctata. d'Orbigny. 



Bolivina imnctata d'Orbigny, 1839, Foram. Amer. Merid., p. 63, pi. viii, 



figs. 10-12. 

 B. punctata Brady, 1884, Chall. Eept., p. 417, pi. lii,fig. 18, 19. 



Good examples are present. They are long and narrow. 



Bolivina rohusta Brady. 



Bolivina rohusta Brady, 1884, Chall. Eept., p. 421, pi. liii, figs. 7-9. 

 B. rohusta Heron-Allen and Earland, 1915, Foram. Kerimba Archipelago, 

 Zool. Soc, vol. XX, pt. xvii, p. 646. 



The type-form is well represented. Most of the tests have the 

 spine at the base ; in the other cases it has most probably been 

 broken off. 



There are more numerous specimens of what appears to be a 

 weak form. These are much narrower, and the edges of the test 

 are rounded off. There is no basal spine. Probably this is one of 

 the forms referred to by Heron- Allen and Earland in the above 

 reference.
