Bairdia FORMOSA, G. S. Brady. (Plate 56. fig. 21.) 



Bairdia formosa, G. S. Brady ('68^), p. 221, pi. 14. figs. 5-7 ; id. ('80), p. 53, pi. 10. 

 figs. 1 a-e. 



Two valves were found in the present soundings, both of which represent 

 young individuals. One of these is more elongate than usual, but in this it 

 resembles the forms found by Brady in the Mediterranean ; and instead of 

 the numerous spines at the extremities, there is only one stout spine at each 

 end. The other valve is more typical in outline, and bears a few minute 

 spines at the posterior end along with a stronger terminal spine. 



Occurrence. — Sta. 13, 1050 fms. 



Bairdia milne-edwardsi^ G. S. Brady. 



Bairdia milne-edwardsi, G. S. Brady ('67), vol. i. p. 139, pi. 17. figs. 3, 4; id. ('80), p. 56, 

 pi. 10. figs. 4 a-g ; id. ('90), p. 494 ; Chapman ('02^), p. 422. 



The examples previously recorded from Funafuti were mainly from shallow 

 depths, with one from 200 fathoms. Dr. Brady obtained this species from 

 only one locality, viz. off St. Vincent, Cape Verde, 1070-1150 fathoms. 



Occurrence. — Sta. 13, 1050 fms. ; 55, 507 fms. 



Bairdia victrix, G. S. Brady. 



Bairdia victsix, G, S. Brady ('80), p. 66, pi. 10. figs. 5 a-d. 

 Occurrence. — Sta. 13, 1059 fins. One separate valve. 



Bairdia woodwardiana, G. S. Brady. 



Bairdia ^voodwardiana^ G. S. Brady ('80), p. 57, pi. 11. figs. 1 a-e; id. ('90), p. 494; 

 Chapman ('02^), p. 421. 



The ' Challenger ' dredgings yielded this species from one locality only, viz., 

 Tongatabu, 18 fathoms ; and Dr. Brady has since found itatTaviunij S. Seas. 

 Occurrence.— ^i^. 2, 1489 fms. ; 13, 1059 fms. ; 55, 507 fms. 



Baiedia crosskeiana, G. S. Brady. 



Bairdia crosskeiana, G. S. Brady ('66), p. 866, pi. 57. figs. 10 a-d; id. ('80), p. 68, pi. 9. 

 figs. 3 a-c ; Brady & Norman ('89), p. 115, pi. 10. figs. 3, 4 ; Chapman ('02="), p. 421. 



A single valve, comparable in edge view with that figured by Brady and 

 Norman. The posterior extremity terminates in a short spine. 

 Occurrence. — Sta. 55, 507 fms. 



Bairdia expansa, G. S. Brady. 



Bairdia expansa, G. S. Brady ('80), p. 68, pi. 11. figs. 2 a-e; id. ('90), p. 495. 



In edge view this species is very broad and tumid. In our specimens the 

 anterior border is more evenly rounded. The expanded and denticulate 

 margin is similar to Brady's specimen, found off Honolulu at 40 fathoms.
