depths less than 75 fathoms (137 meters). Specimens occurred at 

 most of these stations in considerable numbers. 



This species, which would probably be included by some writei's 

 under //. canariensis, seems to be distinct from that species as cbn- 

 sidered here. It is much larger, has a larger number of chambers, 

 is thicker, and more nearly circular in side view. Its range is appar- 

 ently mostly confined to waters of less than a hundred fathoms in 

 depth. It is closely similar to the specimen figured by Brady in the 

 Challenger report (pi. 85, fig. 4).

Description.— Test planospiral, composed of three or more coils, 

 not completely involute, compressed in the earlier coils but the last 

 few chambers typically inflated, chambers 7-S in the last-formed coib 

 rapidly increasing in breadth in the last-formed portion; wall com- 

 posed of sand grains with a varying amount of sponge spicules, 

 somewhat roughly finished, interior smooth, the wall especially in 

 the last-formed chamber thick and labyrinthic resembling Cyclam- 

 miria in this respect; aperture a narrow, elongate, somewhat curved 

 slit at the base of the last-formed chamber; color yellowish or reddish 

 brown, occasionally white or gray. 



Diameter up to 1.75 mm. 



Distribution. — Brady in his original notes on this species says that 

 his best si)ecimens were from Challenger station 23, oil' Som])rero
