14 SiDEBOTTOM, Foraminif era from the Isla?id of Delos. 



Three varieties occur which have the two keels, and 

 although very different in other respects, I have brought 

 them together under the above heading. Fig. 13 has the 

 two keels well developed, but has no neck, and is of fre- 

 quent occurrence. Fig. 14 has a well developed neck with 

 phialine lip surrounding the orifice, also a ridge on either 

 side encircling the body of the test, and is rare. Fig. 15 

 has the keels very poorly developed and is frequent. All 

 the varieties have the internal tube attached to one face 

 of the test.

The examples agree with the form figured by Messrs, 

 Balkwill and Millett in the above reference. Frequent. 



* Lagena fimbriata, Brady.

 pi. 2, fig. 5. 



Brady, in the " Challenger " Report, speaks of this as 

 being a deep-water form, but it has been found both by 

 Mr. Millett and Mr. Wright in shallow-water off the coast 

 of Ireland. The two or three specimens found at Delos 

 agree well with the Irish forms, although in the former 

 the oval wing surrounding the base is not well developed 

 and is more compressed. Very rare. Better examples 

 occur at Palermo.
