10 SiDEBOTTOM, Fovaminiferafrom the Island of Delos. 



L. sqiianioso-marginata (P. & J.), Brady ('84), p. 481, 

 pi. 60, fig. 24. 



L. squamoso-inarginata (P. & J.), Millett (:0l), p. 622, 

 pi. 14, fig. 7. 



All the specimens have a single keel. The ento- 

 solenian tube is attached. The mouth opens out at the 

 lower edge of the keel, and the hexagonal markings are 

 raised. About thirty found. Rather rare.

This elegant foraminifer is frequent in these gatherings. 

 The keel varies in its development, in some cases it 

 scarcely shows, in others it springs from the edge of the 

 mouth and is continuous right round the test, being 

 widest at the aboral end. The internal tube is straight 

 and free. In all the examples the centre of the test is 

 unornamented. One specimen of trigonal form occurs.

Lagena marginata (W. & B.), var. inaequilateralis^ 

 Wright, ('86) p. 321, pi. 26, fig. 10. 



The specimens are quite typical, beautifully clear, and 

 in all cases the internal tube is attached to the test ; the 

 mouth is peculiar and agrees with the Irish examples. 

 Frequent. 



Lagena inaequilateralis (Wright), var. semi-marginata, 

 nov. (PI. 2, fig. 7). 



This is an interesting variation of L. marginata var. 

 inaequilateralis^ Wright. The mouth is the same as in
