FOEAMINIFERA OF THE ATLANTIC OCEAN 



105 



This is a highly developed species becoming very broad in its later 

 chambers. The figures, (pi. 18, figs. 3a-c) copied from those of 

 Brady in the Challenger Report, are from off Prince Edward Island. 

 Brady gives the following Atlantic records: "ten 'Porcupine' stations 

 in the North Atlantic, depths from 155 to 1,630 fathoms; four points 

 on the coast of Norway, 30 to 160 fathoms (Parker and Jones); the 

 Shetland Seas, 75 to 90 fathoms; off the Azores, 450 fathoms; and off 

 the Canaries, 600 fathoms; in the South Atlantic, off Pernambuco, 350 

 fathoms; off Tristan d'Acunha, 100 to 150 fathoms; and north of the 

 Falkland Islands, 1,035 fathoms." 



The following variety may be distinguished: 



Anomalina coronata — Material examined 



ANOMALINA CORONATA Parker and Jones, var. CRASSA, new variety 



Plate 19, figures 1, 2 



Test very broad and thick, the umbilical areas covered with a 

 secondary thickening of calcareous wall which is irregularly perforated 

 by canals leading to the umbilical area. 



Holotype of variety (Cat. No. 21887, U.S.N.M.) from Albatross 

 Station D2063, off the eastern coast of the United States, in 141 

 fathoms. 



At the type station this variety is very abundant. Even in the 

 early stages the great thickening of the test is shown.
