Adelosina IcBvigata, d'Orbigny ('46), p. 302, pi. 20, 

 figs. 22-24. -^- Icsvigata (d'Orb.), Schlumberger ('86), p. 549,

The amount of tilting of the central chamber varies 

 considerably, and the last chamber is sometimes very 

 faintly striated. The test is polished. Frequent. 



*Miliolina undosa, Karrer, sp. 



Miliolina undosa (Karrer), Brady ('84), p. 176, pi. 6, 

 figs. 6-Z. 



In the Delos form all the edges of the chambers are 

 striated, and the strise often run down the sides of the 

 chambers. Frequent. 



Miliolina undulata, d'Orbigny. 



Quinquelocidina undulata (d'Orb.), Schlumberger ('93), 

 p. 213, pi. 2, figs. 61, 62. 



The specimens agree with the above reference. 

 Common. 



^Miliolina pygmaea, Reuss, sp. (PI. 4, figs. 4-6). 



Miliolina pygmcsa (Reuss), Brady ('84), p. 163, pi. 113, 

 fig. 16 a, b. 



The test is slightly roughened, the mouth circular and 

 toothed. Frequent. 



Miliolina contorta, d'Orbigny, sp. 



Quinquelocidina contorta, d'Orbigny ('46), p. 298, pi. 20, 

 figs. 4-6. 



The test is not polished, but is slightly rough. The 

 neck is rather more produced than in d'Orbigny's figures. 

 Frequent. 



The specimens (PI. 4, figs. 7-9) I have figured are 

 apparently a feeble variety of this variable species. 

 Common.
