inflated. At Palermo, fourteen were found, of which 

 eleven have the hispid chamber. They seem too com- 

 plete a series to be considered as monstrosities. Figs. 4, 

 5, 6, no doubt are young examples, and belong to the 

 same series. 



The tests (with the exception of the primordial and 

 final chambers) are compressed, and, having oblique sutures 

 and marginal apertures, would appear to be Vaginuline in 

 their manner of growth. Fig. 8 is a side view of the test. 

 The specimens from Palermo are rather more regular in 

 form than those from Delos, as may be seen from the two 

 outlined above. 



POLYMORPHININyE. 

 Polymorphina, d'Orbigny. 



*Polymorphina lactea, Walker and Jacob, sp. (PI. 2, 

 fig. n.) 



Polymorphina muensteri (W. & J.), Reuss ('55), p. 249, 

 pi. 8, fig. 80. 



Globulina roemeri, Reuss ('55), p. 245, pi. 6, fig. 63. 



Polymorphina lactea (W. & J.), typica (pars), William- 

 son ('58), p. 71, pi. 6, fig. 147, and P. lactea (W. & J.) var. 

 communis, Williamson ('58), p. 72, pi. 6, figs. 153-155. 



P. lactea (W. & J.) Brady, Parker and Jones ('70), 

 p. 213, pi. 39, fig. 1. 



Even allowing considerable latitude as to variations 

 in form, this species is rare in the Delos material. The 

 example figured is not typical. 



Polymorphina amygdaloides, Reuss. (PI. 2, figs. 12-14.) 



Polymorphina amygdaloides, Reuss ('55), p. 250, pi. 8,
