twelve) pyriform in shape, the proximal part of each' chamber 

 broadest, thence tapering gently toward the distal end, chambers 

 gradually increasing in size toward the distal end of the test, exterior, 

 in the large form with short chambers, roughish, in the 

 form with long chambers, smooth; aperture large, at 

 the end of the tapering chamber; color usually grayish. 

 Length very variable, up to 25 mm. 

 Distribution. — There are ten published records for 

 this species which with the new stations from the 

 Albatross and Nero soundings give a very general dis- 

 tribution for this species in the North Pacific, depths 

 ranging from 941-3,950 fathoms. 

 '^0&k Bagg's specimen from Albatross station H4585 



l^llfl assigned to this species is Reophax dentaliniformis 

 II. B. Brady, as I find upon examination of his ma- 

 terial. Goes's specimens, as well as all other North 

 Pacific material that I have seen, are like plate 31, figs. 

 |w§f| 3 and 4 of the Challenger Report. Some of Goes's 

 specimens had nine chambers. His specimens from 

 the Caribbean Sea are more like figures 6-8 of the same 

 plate, and it is very probable that Brady has included 

 more than one species under this name. Egger's fig- 

 ures seem to represent a mixed assemblage of little 

 character, none of which appears to be a typical Reo- 

 phax nodulosus.

Description. — Test elongate, nearly straight, com- 

 posed of from 3-8 chambers, typically pyriform, broad- 

 est at the base and rather rapidly narrowing to the 

 aperture at the distal end of the chamber, wall com- 

 posed of coarse sand grains, rather roughly cemented ; 

 color yellowish-brown.

 the only records for tile North Pacific for this species are from the 

 Challenger material, stations 237 and 246, 1,875 and 2,050 fathoms, 

 east of Japan.
