8 BULLETIN" 104, UNITED STATES NATIONAL MUSEUM. 



Description. — Test composed of a few (3-5) subglobose chambers 

 in a straight or more commonly curved line, each as added much 

 larger than the preceding; wall of coarse sand grains with a rather 

 neat exterior, apertural end with a slight protuberance and a smaller 

 aperture; color reddish or yellowish brown or gray. 



Length up to 2.5 mm. 



Distribution. — Brady had this species from five Porcupine sta- 

 tions in the North Atlantic west and southwest of Ireland and from 

 a few Challenger stations in deep water, off the eastern coast of the 

 United States, near the Azores, northeast of Puerto Rico, off the 

 coast of South America, off Brazil and Buenos Aires, off the coast of 

 Africa, and off the Cape of Good Hope. 



Pearcey records it from several stations in the Antarctic; Brady, 

 Parker, and Jones record it from the Abrohlos Bank off Brazil, but 

 their figured material does not seem to belong to this species. It 

 is also known from various parts of the Pacific (Brady, Goes, Cush- 

 man). 



I have seen a set of this species from Porcupine station 19, selected 

 by W. B. Carpenter and now in the United States National Museum. 

 This shows a short, but large, robust species entirely unlike any- 

 thing found on our coast, so far as I have seen material. A smaller 

 form which in general resembles this w^as found at five stations to 

 the northeastward of that recorded in the Challenger Summary of 

 Results, station 44, and two Albatross stations . in the northern 

 part of the Gulf of Mexico. Flint's material was from Albatross 

 D2760, off Bahia, Brazil, in 1,019 fathoms (1,864 meters).

Description. — Test short and thick, composed typically of three 

 chambers, increasing rapidly in size as added, last-formed chamber 

 making up a large proportion of the test, fusiform or elliptic, axis of
