Distribution. — Recorded by Goes from the eastern portion of the 

 North Pacific in 695-1,832 fathoms, and by Bagg from the Hawaiian 

 Islands, in 275-1,544 fathoms, with the average depth below 400 

 fathoms. 



I have had material from Nero station 990, in 859 fathoms, near 

 Guam, and from stations about Japan, in the Inland Sea, and in 

 Bering Sea, from depths ranging between 120 fathoms and 898 

 fathoms. Specimens were nowhere common. 



Although Reuss' name has been used for all the broader forms 

 which could not well be included under B. 'punctata d'Orbigny by 

 various writers, there is, as is seen from a study of the present 

 material, a definite species with the characters given above. It is 

 apparently very distinct from B. punctata, with chambers of a very 

 different form. 



BOLIVINA SEMINUDA, new species. 



Description. — Test elongate, subcylindrical, very slightly com- 

 pressed, the apical end rounded; chambers numerous, 

 high, very slightly inflated, sutures nearly flush; wall 

 hyaline, finely punctate except the lower half of each 

 which has coarse foramina, otherwise smooth; aper- 

 ture elongate, loop-shaped; color transparent and 

 whitish about the lower half of each chamber. 

 Length up to 1 mm. 



Distribution— Specimens of this species were fairly 

 common at two Albatross stations in Bering Sea, 

 I station H4025, in 536 fathoms, and station D4775 



*•■ (type), on Bowers Bank, in 584 fathoms. 



Y Type.— Cat. No. 8338, U.S.N.M. 



V The cylindrical form and the very peculiar orna- 



,' mentation of the test distinguish this species. The 



test is hyaline and the lower half of the chamber, 

 ^EMram>A° L x 60* ins tcad of being spinose or granular as in B. spinescens, 

 is characterized by coarse foramina. No specimens 

 were found except in Bering Sea.
