 78), from the great lake of Para, in Brazil/ 



The genus Area is enriched by Philippi (Heft. 2) with a very peculiar 

 species, A. Hemicardium, Koch, which is anteriorly, truncated directly down- 

 wards from the beak ; the posterior cardinal teeth are uncinate, and form an 

 angle open posteriorly. This species might very properly be taken for the 

 type of a new genus. Its native locality is not given ; it comes, however, 

 from Peru, where it was collected by Dr. v. Tschudi. In the same plate 

 are also figured A. tuberculosa, Sow., Irasiliana, Lain., and pexata, Say. 



Pectimculus giganteus, from California, raripictus, aurifluus, and holosericus,

 from Ceylon, Uncatus, from the West Indies, obliqmts, from Swan Piver,

 incrassata, /3, and C. Preissii, under that name; C. tridacnoides he also 

 explains to be (ib.) C. crassicostata, Lam. Reeve describes (Proc. p. 191) 

 21 more species of this genus. 



Lovell Reeve gives 7 new species of Cyprlcardia, which are figured in the 

 ' Conch, iconic.' .- C. serrata, decussata, vellicata, incarnata, laminata, obesa, 

 solenoides. (Proc. p. 195.) 



In the plate of the second part of Philippi' s Conchyliological work, which

 Lam., semicancellata, Koch, from Java, V. Kochii, Pliil., without native lo- 

 cality, and V. qfricana, v. Miihlfeld, from the Cape of Good Hope. Menke
