We shall do best to take D'Orbigny's Model no. 96, rather 

 than the Soldanian figures referred to, as the type of Q. secans] 

 and with this in view we have no hesitation in placing 

 No. 150 {Q. vulgaris), as well as the drawings indicated in the 

 reference given above, under the same species. Indeed the 

 drawing named Q. vulgaris by D'Orbigny more nearly resem- 

 bles the " Model" than those do to which he gives the name 

 Q. secans.

 and the Mediterranean ; fossil at Castel-Arquato." (Mediter- 

 ranean, Soldani.) 



Amongst all Soldani's figures we do not find one that is 

 quite a good representative of the central type of the Milioline 

 group. Possibly that selected by D'Orbigny is as near as 

 any, but it approaches Q. hicornis in the partial striation of 

 the later chambers.

" Hob. Fossil at Castel-Arquato." (Mediterranean, Soldani.) 



A feeble intermediate form, best disposed of by being placed

An attenuated variety of Q. seminulum, with partial stria- 

 tion at the base of the chambers.

The genus Adelosina, instituted by D'Orbigny and adopted 

 by some subsequent writers, has by common consent been 

 abandoned, since it has been shown that it only represents a
