Distribution. — The records given by Brady in the Challenger 

 report for Nodosarla costuJata from three stations in the Northern 

 Atlantic, off Sombrero Island, 460 fathoms (823 meters), off Cule- 

 bra Island, 390 fathoms (713 meters), and off Bermuda, 435 fathoms 

 (796 meters). He also records it from one station in the Philippine 

 Islands, 95 fathoms (174 meters). Flint's records for Nodosaria 

 costulata are both in the northern part of the Gulf of Mexico. I have 

 seen his material and it seems to be Nodosaria 'pyrula^ var. semi- 

 rugosa. I have also had material from the Gulf of Mexico and the 

 Caribbean. It is recorded from the Malay Archipelago by Millett, 

 and I have had it from off southern Japan as well as from numerous 

 stations in the Philippine region. It usually occurs, as the records 

 of Flint, Brady, and mine show, at depths of 100-500 fathoms (183- 

 914 meters). 



Nodosaria pyrula, var. semirugosa — m^derial examined. 



NODOSARIA PYRULA D'Orbigny. variety. 



At four Albatross stations, all in the general locality southeast of 

 Nantucket, there are broken specimens of a variety of Nodosaria 

 fyrula which have much more elongate chambers than the typical 

 form from farther south.

I have had a few specimens from stations in the Gulf of Mexico 

 and in the Caribbean which are very similar to specimens figured 

 by Brady in the Challenger report (pi. 62, figs. 17, 18) under this
