it at two Challenger stations in 1,850 and 2,050 fathoms; Goes 

 records it from two Albatross stations, D3375, in 1,201 fathoms, and 

 D3376, in 1,132 fathoms; Bagg records it from four Albatross stations 

 near the Hawaiian Islands, H4430, in 1,544 fathoms, H4555, in 1,398 

 fathoms, H4568, in 1,274 fathoms, and H4571, in 384 fathoms; Flint 

 records it a from Nero station 613, in 1,072 fathoms. 



In the material I have examined, the species has been frequently 

 found in the vicinity of the Hawaiian and Galapagos Islands, Guam, 

 off Japan, etc. The average depth of the stations is about 1,000 

 fathoms. 



From an examination of the original figure and description given 

 by d'Orbigny, it seems clear that our rather common recent form is 

 not the same as his cretaceous species. Goes came to the conclu- 

 sion that Brady's union of the two was incorrect. However, to 

 unite both this species and G. chilostoma as Goes has done, both 

 under the latter name, does not seem to me to be a solution of the 

 matter, as the two seem to be very distinct. As no other name is 

 available, a new name is here proposed. This is one of the cases 

 where it would seem to have been better if Brady had proposed a 

 new name instead of uniting different things, as the Challenger Report 

 has been looked to so long as a standard that Brady's distinctions 

 in regard to original figures and descriptions have not always 

 been investigated by later authors. A new name at that time and a 

 recognition of the existing differences would have cleared the 

 synonymy greatly.

Description. — Test elongate, tapering 

 gradually to the somewhat acute initial 

 end; early portion composed of triserially 

 arranged chambers with rounded angles 

 and forming the lesser portion of the 

 test; later portion biserial, often some-

Distribution. — The only records for this species in the North Pacific 

 are the specimens recorded by Brady from Challenger station 206, 

 in 2,100 fathoms, between China and the Philippines.
