2 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 75 



Except for this classic work of d'Orbigny, very little has been col- 

 lected or published from this area. There are a number of records 

 in the Challenger report from collections made by the Challenger 

 among the islands of the southern part of the Chilean coast, but only 

 a few of these stations were included in those studied by Brady. The 

 United States Bureau of Fisheries steamer Albatross in the voyage up 

 the west coast of South America made a few collections off the coast, 

 but for the most part these are not now available and nothing has as 

 yet been published on them. Berry published a short note ^ on a 

 new Nonion from the coast of Peru. His species we have found in 

 some numbers in some of the samples we have studied. Altogether 

 this is one of the least known of the oceanic areas unless we except 

 the Western coast of Africa. 



Very few of the forms are new but a few of them appear to be 

 undescribed. Nearly all of the species are illustrated and we have 

 to thank Miss Margaret S. Moore for her painstaking work in maldng 

 the drawings from selected specimens. The following are the species 

 obtained in the collections:

Reophax fusiformis (of Authors). 



There is a single fusiform specimen from Lota, Chile. It has an 

 arenaceous test and apparently a single chamber. The species is a 

 widely distributed one known from a number of stations in the 

 Pacific at various depths.
