Globigerina are largest here and most common. In the middle 

 depth also these two genera present the best developed forms both 

 in number and size. 



One of the Rhizopods in the Tejares Clay particularly deserves 

 notice, namely the Frondicularia, which we here find very large. 

 Soldani figures similar large specimens from the Siennese deposits ; 

 but we have met with small ones only. In the recent sand from 

 Rimini we find large, worn, and probably " derived " Frondicularia^, 

 having their chambers occupied with ferruginous clay, as is the case 

 with the large fossil Cristellaria of Sienna. D'Orbigny had large 

 Frondicularia} from the Viennese Tertiaries ; and we find some in 

 the Tertiary beds of San Domingo*. 



IS o.22. Turin (Geol. Soc). 



Characterized by very large Nodosarim and Gristellarice, the 

 Turin deposits which we have examined have the general features 

 of the Pliocene Tertiary. A considerable number of forms, just as 

 may be found on the' western shores of Italy at this day, combined 

 with gigantic Gristellarice and the largest of known Nodosariai, com- 

 pose the fauna in this column No. 22. 



No. 23. Palermo (Geol. Soc). 



Our specimens from the tertiary deposits of Palermo yield a very 

 rich fauna of rather shallow-water forms, commingled with some 

 from deeper zones. Ampliistegina is present here also, and is common, 

 though not preponderating. The Textularian, Rotalian, and Miliolite 

 groups are in force ; there are a few traces, however, of the Nodo- 

 sariai and Gristellarice. This fauna has much resemblance to the 

 large assemblage of forms which Mr. S. V. Wood, F.G.S., has col- 

 lected from the Crag at Sutton in Suffolk. With the latter, however, 

 the existing sea-bed/ at 21 fathoms f, off the north-west of Sicily, 

 has such close relations, as to the varieties and conditions of the 

 Foraminifera, that we may regard them as almost identical. 



No. 24. Malta (Geol. Soc). 



The Heterostegina-bed at Malta is not without smaller Fora- 

 minifers (some of which we can identify, — as the Globigerina bul- 

 loides, Truncatulina lobatula, <fec), but the matrix is too stubborn 

 to yield all its treasures. The Heterostegina% (which is found also 

 in the Vienna Basin) appears to be extinct in the Mediterranean.

* We have lately met with a long narrow Frondicularia (like F. striatula, 

 Reuss) in Commander Dayman's dredgings, made in July 1859, off Lisbon, at 

 700 fathoms.— May 26, 1860.

\ Spratt, Forbes, and Wright, in their notices of the Maltese strata and fossils 

 (Proc. Geol. Soc. iv. pp. 226 & 230 ; and Annals Nat. Hist. 2 ser. xv. p. 101, &c), 

 have misnamed this Foraniinifer, referring it erroneously to Lenticulites ( Oper- 

 culina) complanatus, Easterot. Operculina complanata occurs in a hard white 

 limestone at Malta ; and for a very fine specimen we are indebted to Lord 

 Ducie, F.G.S. ■ •: '.'
