DK. PI-IILIPPI S COMPARATIVE TABLES OF MOLLUSCA.

* Paludina thermalis L. (I have received two different species under the 



name Turbo minuius Say, the smaller of which I cannot distinguish 



from P. thermalis.) 

 Crepidula unguiformis Lam. (C. plana Say) 



Scalaria communis Lam. ? (In North America appears a small white va- 

 riety, which may be another species) 

 *Buccinum undatum L. 



* Purpura lapillus L. 



Of these species, those marked (*') are not found in the Mediter- 

 ranean. The above list contains, however, certainly but a small 

 part of the species common to the two hemispheres ; for Say, in 

 his American Conchology, in speaking of Paludina vivipara, ob- 

 serves, " this appears to be one of several species common to North 

 America and Europe." 



8. Comparison of the Cuba Fauna with that of South Italy. 



For obtaining this comparison I have availed myself partly of 

 Pfeiffer's Catalogues, containing 289 species (Archiv. for 1839, 

 p. 346., and 1840, p. 250.), and partly of D'Orbigny's, in Ramon 

 de la Sagra's " Hist. Physique, &c, de ITsle de Cuba," which 

 latter, however, I have only been able to refer to as far as 

 No. 293. Two or three species I have been able to add which 

 my brother, E. B. Philippi, collected at Matanzas in 1835. 



The species in the following list, whose presence in the Mediter- 

 ranean is doubtful, are marked thus (f) : —
