2 SiDEBOTTOM, Foraviinifera from the Island of Delos.

Lagena botelliformis, Brady ('84), p. 454, pi. 56, fig. 6. 



The contour of the Delos specimens so closely resem- 

 bles Brady's figure in the above reference, with the 

 exception that the orifice is situated at the end of a 

 produced neck, that I think it may be considered a varia- 

 tion of that species, in preference to treating it as a variety 

 of L. laevis. L. laevis does not occur in the material 

 examined. Six specimens were found, only one at 

 Palermo. Very rare. 



*Lagena ampulla-distoma, Rymer Jones (PI. i, figs. 2,3). 



Lagena vulgaris, var. ampulla-distoma, Ry. Jones ('72)> 

 p. 62>, pi. 19, fig- 52.

L. ampulla-distoina (Ry. Jones), Millett (:0l), p. 5, 

 pl. I, fig. 5. 



This occurs in three forms. In the four largest 

 specimens the test is roughened all over, as in fig. 2 ; in 

 the smaller ones only half of the test is rough, and the 

 shell deposit takes the form of very short blunted spines, 

 which have a tendency to coalesce and run into lines as 

 they approach the clear part of the shell, as in fig. 3. 

 Whilst in the smallest examples (and they are very minute) 

 the shell is covered with protuberances which show a still 

 greater tendency to run into lines — in fact, in one case 

 they have nearly done so. All the forms are very rare. 

 More frequent at Palermo. 



* Lagena striata, d'Orbigny, sp. 



Oolina striata, d'Orbigny ('39), p. 21, pl. 5, fig. 12. 

 L. striata (d'Orb.), Brady ('84), p. 460, pl. 57, figs. 19, 

 22, 24, 28—30.
