some cases. A good specimen from Delos laid alongside 

 a not very well-developed one from Raine Island, shews 

 great similarity in many respects. 



It may be a passage form in the direction of Sagrina 

 nodosa., P. & J., but I have not come across a single 

 Sagrina of any description in the Delos dredgings. 

 Rather rare. 



GLOBIGERINIDtE. 

 Globigerina, d'Orbigny. 



*Globigerina bulloides, d'Orbigny. 



Globigerina bulloides, d'Orbigny ('39), p. 132, pi. 2, 

 figs. 1-3. 



G. bulloides, d'Orbigny ('46), p. 163, pi. 9, figs. 4-6. 



G. bulloides (d'Orb.), Terquem (^'75), p. 31, pi. 4, 

 figs. 5, «, ^. 



G. bulloides (d'Orb.), Brady ('84), p. 593, pi. 79, 

 figs. 3-7. 



G. bulloides (d'Orb.), Silvestri ('98), p. 245, pi. 4, 

 figs. 7-9. 



Occurs in two forms, one of which is smaller, more 

 transparent, and much more planospiral than the other. 



*Globigerina triloba, Reuss. (PI. i, fig. 8.) 



Globigerina triloba, Reuss ('50), p. 374, pi. 47, fig. 11. 

 G. triloba (Reuss), Terrigi ('80), p. 188, pi. i, fig. 18. 

 G. bidloides, var. triloba (Reuss), Brady ('84), p. 595, 

 pi. 79, figs. I, 2, and pi. 81, figs. 2, 3. 



I very much doubt if this form should be treated as a 

 " species," or, rather, as the immature condition of some 

 other species of Globigerinae. Very rare.
