FORAMINTFERA OF NORTH PACIFIC OCEAN. 



85 



own work I have found specimens from a large number of stations, 

 especially in the Western Pacific about Japan, and southward, and 

 also in the deeper water in various places. It has occurred also in 

 material from between Hawaii and the western coast of America. 

 Of these various stations the shallowest at which I have found the 

 species is 181 fathoms, and the deepest 1,417 fathoms. 



The species, although widely distributed, has not been met with 

 in any considerable numbers at any one station. 



Brady speaks of tins species as a transition form connecting Bulimina 

 aculeata and B. buchiana, but it has always been easil}- distinguished 

 from either of these two species in the material I have examined. In 

 a large list of stations the two species B. in fata and B. buchiana 

 occurred at the same station but twice. 



As far as the North Pacific is concerned Bulimina injlata seems to 

 be the most common species of the genus.

Description. — Test ovate, short, composed 

 of numerous inflated chambers; sutures fairly 

 deep, triserial; chambers visible from base to 

 apex; ornamentation consisting of a series of 

 raised costa 3 , usually three to five on each 

 chamber, and becoming confluent with those 

 on the chambers directly above and below, so 

 that the test has the appearance of bearing 

 longitudinal costae from the early chambers 

 to the basal portion of those last formed ; wall thin and transparent in 

 young specimens, in adults becoming thickened, white, and opaque,
