6 SiDEBOTTOM, Foraminifera from the Island of Delos. 



Three specimens of the ordinary kind occur in 

 trigonal form.

Fissurina acuta, Reuss ('62), p. 340, pi. 7, fig. 90. 



F. apiculata, Reuss ('62), p. 339, pi. 6, fig. 85. 



Lagena laevigata (Reuss), var. acuta, (Reuss), Millett 

 (:0I), p. 494, pi. 8, fig. 16. 



This apiculate form of L. laevigata is frequent. 



*One of these chosen for illustration, fig. 8, is inter- 

 esting from the fact that the outline is inequilateral. 

 This latter variety is rare, 



*Lagena lucida, Williamson, sp. (PI. i, figs. 9 — 12). 



Entosoknia inarginata, var. lucida, Williamson, sp. ('58), 

 p. 10, pi. I, figs. 22, 23. 



Lagena lucida (Williamson) Balkwill and Millett ('84), 

 p. 80, pi. 2, fig. 7. 



In the Delos examples of this species the form of the 

 test is very variable, as will be seen by reference to the 

 figures. In one form only is the apiculate variety present, 

 fig. 12, and this has the entosolenian tube attached, in the 

 other varieties it is short, straight, and free. Frequent. 

 All the varieties occur at Palermo. 



* Lagena fasciata, Egger, sp. (PI. i, figs. 13 — 16.)
