406 MR. p. CHAPMAN ON DEEP-SEA FORAMINIFERA 



Cassidulina calabra, Seguenza, sp. 

 Occurrence. — Sta. 105, 2400 £ms. 



Cassidulina bradii, Norman. 



The present records are from unusually deep water, since the ' Challenger ' 

 gives its deepest limit, in the S. Pacific, at 1450 fathoms. The examples are 

 typical and show all stages of growth. 



Occurrence.— ^isi. 3, 2715 fms. ; 45, 2107 fms. ; 105, 2400 fms. 



Cassidulina bradii, var. attenuata, nov. (Plate 54. fig. 4.) 

 Test smooth, almost cylindrical in section, elongate ; coiled commencement 

 inconspicuous, followed by a long, reflexly curved series. Aperture resembling 

 that of the specific form, but longer. Length 1 mm. ; greatest breadth, 

 near middle of upper third, '212 mm. 

 Occurrence. — Sta. 105, 2400 fms. 



Genus Ehrenbergina, Reuss. 

 Ehrenbergina pupa, Orh. 

 Occurrence. — Sta. 13, 1050 fms. 



Ehrenbergina serrata, Reuss. 



Some of our specimens, from great depths, are furnished with very delicate 

 spines. 



Occurrence.— ^i■^i. 2, 1489 fms.; 3, 2715 fms.; 13, 1050 fms.; 20, 

 1215 £ms.; 45, 2107 fms. ; 48, 2298 fms. ; 105, 2400 fms. ; 150, 2438 fms. 



Ehrenbergina hystrix, Brady. 



This rare and handsome species appears to be restricted to the S. Pacific, 

 in deep water. 



Occurrence.— ^iii. 3, 2715 fms. ; 150, 2438 fms. 



Family CHEILOSTOMELLIDiB.

8. pellucida, Brady ; Millett ('01), Rep. Malay Foram. p. 3, pi. 1. fig. 4.
