The forms figured by M. Schlumberger as Quinquelocti- 

 lina dilatata (d'Orb.) ('93), p. 217, pi. 3, figs. 70-74, and 

 pi. 4, figs. 87-90, are numerous. Yet another form of this 

 variable species is present (PI. 3, figs. 1-7; Section 2). 

 The young, or biloculine form is common and the trilo- 

 culine one frequent. The nearest figures I have seen of 

 the triloculine specimens are the Triloculina truncata, 

 Karrer ('64), p. 704, pi. i, fig. 2. 



^Miliolina suborbicularis, d'Orbigny, sp. 



Quinqueloailina suborbicularis (d'Orb.), Schlumber- 

 ger ('93), p. Ji, pi. 2, figs. 6},, 64, pi. 3, fig. 67 and woodcuts, 

 26-28. Miliolina suborbicularis (d'Orb.), Millett ('98), p. 502, 

 pi. 1 1, fig. 13. 



Present in great numbers, and many of the specimens 

 have a hauerine tendency, showing three chambers in the 

 last whorl. My friend, Mr. F. W. Millett, tells me this 

 tendency appears in fossil specimens as figured by Ter- 

 quem. Common. 



* Miliolina marioni, Schlumberger, sp. 



Triloculina mariotii, Schlumberger ('93), p. 62, pi. i, 

 figs. 38-41, and text-figs. 7, 8. 



M. Schlumberger kindly sent me specimens from the 

 Mediterranean, and those from Delos agree with them. 

 The groove in the centre of the back chamber, as repre- 

 sented in the above reference, does not show in the 

 specimens submitted to me, nor is it present in the Delos 

 forms. Many of them, especially in the young state, have 

 a strong resemblance externally to M. tricarinata. 

 Frequent.
