12 SiDEBOTTOM, Foraniinifera from the Island of Delos. 



*Miliolina auberiana, d'Orbigny, sp. 



Miliolina auberiana (d'Orb.), Brady ('84), p. 162, pi. 5, 

 figs. 8 a^ b, 9. 



The Delos forms of this variety of M. seminuhim are 

 not so broad in comparison with the length as those 

 figured by Brady, otherwise they agree well. Frequent. 



*Miliolina cuvieriana, d'Orbigny, sp. 



Miliolina cuvieriana (d'Orb.), Brady ('84), p. 162, pi. 5, 

 ^g.i2a,b,c. M. cuvieriana (d'Orb.), Millett ('98), p. 505, 

 pi. 12, fig. 2 a,b. 



The unornamented specimens are small, with very few 

 exceptions. Common. 



*The Q. seminuda of Reuss with the rounded periphery 

 striated, is also present, along with those which have the 

 periphery square and costate ; the test of the latter ones 

 is generally more compressed. Both are small- Frequent. 



* Miliolina boueana, d'Orbigny, sp. 

 Quinqueloculina boueana, d'Orbigny ('46), p. 293, pi. 19, 

 figs. 7-9. M. boueana (d'Orb.), Brady ('84), p. 173, pi. 7, 



fig- 13- 



The neatness and compactness of the Delos form, 



together with the comparative boldness of the costae, 



incline me to think that this is a young and triloculine 



condition of the above. Common. 



*Miliolina laevigata, d'Orbigny, sp. (PI. 4, figs. 1-3 ; 

 Section 4). 



No. 4. Miliolina Icevigata, d'Orb. x 40. 

 Transverse section of the test.
