Soldani devotes nearly twenty-four of his folio plates (pi. 93. 

 figs, hk-oo might have been added by D'Orbigny) to the illus- 

 tration of the outspread, irregular, and usually adherent varie- 

 ties of Truncatulince ; in all there are no less than 284 figures. 

 Never was a subspecific form so well depicted in all its modi- 

 fications. 



Possibly this form in all its phases may be best placed 

 under Truncatulina tuherosa^ F. & M. sp. (Ann. N. H. ser. 3. 

 vol. V. pp. 177-179). Our limits preclude the reproduction of 

 more than one of Soldani's figures 5 and this, of course, gives 

 no idea of the range of variation so laboriously and clearly 

 exemplified by the indefatigable Soldani and his artists (Giro 

 Santi and A. Costa).

Figs. 0, P are copied, which have little of the sutural 

 limbation characterizing the best-grown specimens, such as 

 D'Orbigny's Model no. 49, and Soldani's pi. 50. fig. ee. In- 

 deed it is rather D'Orbigny's Anomalina rotula (For. Foss. 

 Vien. pi. 10. figs. 10-12), one of the feeblest of the neat flat 

 Planorbulince (Planulince) , that we have here before us.

" Hah. The Adriatic." (Fossil, rare near Sienna, Soldani.) 



Apparently a young specimen of Truncatulina lobatula, the 

 upper view disclosing a little more of the interior whorl of 

 chambers than usual in typical examples.
