414 MR. F. CHAPMAN ON DEEP SEA FORAMINIFERA 



POLYMORPHINA LONGICOLLIS, Brady. 



Polymorphina longioollis, Brady ('84), p. 572, pi. 73. figs. 18, 19 ; Egger ('93), p. 310, 

 pi. 9. fig. 12. 



Dr. Bradj states that no examples in the * Challenger ' collection were 

 found at a less depth than 1100 fathoms. Dr. Egger records this species 

 from the Mauritius at 411 metres. 



Occurrence.— ^in. 3, 2715 fms. ; 21, 2195 fms. 



Genus DiMORPHiNA, Orh. 



DiMORPHlNA (?) LINGULINOIDES, MUlett. 



Dimorphina lingulinoides, Millett ('03), Rep. Malay Foram. p. 266, pi. 5.^fig. 6. 



Our example has lost the terminal portion of the test, but sufficient 

 remains to refer it to the above species. Millett described it from the anchor- 

 muds of the Malay Archipelago. 



Occurrence. — Sta. 13, 1050 fms. 



Genus UviGERiNA, Orh. 



UVIGERINA CANARIENSIS, Orh. 



This is a species usually inhabiting water of moderate depths, although 

 Brady records it from 1900 fathoms E. of Buenos Ayres. 

 Occurrence. — Sta. 3, 2715 fms. 



UVIGERINA PYGM^A, Orh. 



Occurrence.— ^in. 3, 2715 fms. ; 4, 2728 fms. 



UviGERiNA ANGULOSA, Williamson. 

 Occurrence. — Sta. 48, 2208 fms, 



UviGERiNA PORRECTA, Brady. 



This form is recognised as almost peculiar to the coral-reef fauna. It is 

 interesting to note the great depth from whence it was obtained in this area. 

 The deepest sounding hitherto yielding this species was 1850 fathoms. It is 

 not uncommon in the present samples. 



Occurrence.— ^in. 13, 1050 fms. ; 45, 2107 fms. ; 48, 2298 fms. ; 105, 

 2400 fms. ; 109, 604 fms. 



UviGERiNA ACULEATA, Orh. 



This roughly spinous form is rarer than the succeeding, hispid, type. The 

 ' Challenger ' obtained the deepest specimens from 1900 fathoms. 

 Occurrence. — Sta. 3, 2715 fms. ; 48, 2298 fms.
