60 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 



Test large and stout, composed of several chambers, nearly globular 

 or slightly pyriform; wall composed almost entirely of agglutinated 

 foraminiferal tests with a light grayish cement; aperture with a slightly 

 protuberant neck. 



Length up to 5.00 mm. 



Under this species have been placed numerous specimens such as 

 those figured here, which are built largely from other foraminiferal 

 tests. Such specimens vaiy considerably in form but in general have 

 rapidly enlarging chambers with a pyriform shape and a distinct pro- 

 tuberant neck. Localities : 290, 296, 447, 266, 278, 458, 251, 2001, 284, 

 281, 546, 238, 272, 55, 265, 2014, 2009, 82, 487, 331, 2072, 328. 



Distribution. — Station 546 places this species in shallow waters, low 

 tide, off the coast of Ecuador. In the Galapagos Islands, of? Chatham, 

 it has been found at 400 fms. Off Central America and Mexico, numer- 

 ous records indicate a depth range of 10 to 400 fms.

Under this name are placed a large series of specimens which in 

 general are elongate, the chambers increasing rather rapidly in size as 

 added and the aperture rather large and usually at one side of the 

 longitudinal axis. The materials of the wall vary considerably, from 

 pure sand to tests largely composed of sponge spicules or of other ma- 

 terial. On the whole, however, the apertural characters and the shape 

 of the chambers remain fairly constant. Localities: 294, 293, 298, 284,

Distribution. — Off San Pedro in 45 fms.; at low tide in Dype Bay, 

 near Cordova, Alaska ; in the Gulf of California and off Mexico, off 

 Central America, off the Galapagos Islands, and as far south as Gorgona 

 Island, Colombia, in 10 to 15 fms.
