 Plate 43, Figs. 5-8 



Test of medium size for the genus, strongly compressed, periphery 

 rounded, initial end with a single, short spine, early portion rapidly in- 

 creasing in width, in the adult with the sides nearly parallel in the mid- 

 dle then tapering rapidly toward the apertural end, in rare specimens 

 with a third series of chambers developed in the last-formed portion at 

 right angles to the main body of the test ; chambers numerous, distinct, 

 not inflated, rapidly increasing in length but only slightly increasing in 

 height as added ; sutures distinct, slightly thickened but not raised ; wall 

 smooth; aperture radiate, terminal. Length of adult specimens up to

Holotype (AHF no. 69) from Station 2009. 



This species differs from F. sagittula Van den Broeck in the more

 in the adult. 



Stations: 1113, 1118, 1185, 1188, 1189, 1195, 1198, 1238, 2005,

Distribution. — ^The type locality is Inner Gorda Bank, Lower Cali- 

 fornia, Mexico, 23° 00' 50" N, 109° 31' 05" W in 112 fms. Stations 

 1113 through 1238 are in the waters of the Channel Islands. The range 

 beginning with 48 fms. off San Miguel Island, 40 fms. off Santa Bar- 

 bara Island, 37 fms. off San Clemente to 160 fms. off Catalina Island, 

 gives an average depth of 71 fms. Stations 2005-2160 off Mexico show
