10 SiDEBOTTOM, Foraminifera from the Island of Delos. 



Good specimens occur. The height of the spire varies 

 considerably. Rare. 



*Cymbalopora, Hagenow. 

 Cymbalopora poeyi, d'Orbigny, sp. 



Rosalina poeyi, d'Orbigny (.'39J, p. 92, pi. 3, figs. 18-20. 



Cymbalopora ( Rosalina ) poeyi {d'Orh.), Carpenter ('62), 

 p. 215, pi. 13, figs. 10-12. 



C. poeyi (d'Orb.), Brady ('84), p. 636, pi. 102, fig. 13, 

 and var. fig. 14. 



The one specimen found agrees best with the variety 

 figured by Brady ('84), pi. 102, fig. 14. This variety is 

 not at all rare off the island of Rhodes. 



Cymbalopora bulloides, d'Orbigny. 

 Rosalina bulloides, d'Orbigny ('39), p. 98, pi. 3, figs. 



2-5. 



Cymbalopora bulloides (d'Orb.), Brady ('84), p- 638, pi. 

 102, figs. 7-12. 



C bulloides (d'Orb.), Earland (:o2), p. 309, pi. 16, figs. 

 1-6. 



C bulloides (d'Orb.), Millett (:03), p. 697, pi. 7, fig. 4. 



Two examples of this interesting form were found. 

 Mr. Earland, in the above reference, calls attention to the 

 existence of two varieties in this species, viz , the acervu- 

 line and the discorbine. 



The Delos tests belong to the latter one. 



The specimens have the "balloon" chamber smooth, 

 and very transparent, the entosolenian "tube" being 

 clearly seen. Mr. Millett, in his Malay report, refers to a 

 variety of this species which has the " balloon " chamber 

 much crinkled. I have this variety from Mahe harbour, 

 Seychelles Islands, 14 fathoms.
