Although various districts of the Mediterranean have been explored,

 trust that this desideratum will not remain long unsupplied ; in the mean 

 time it may suffice for the object of comparison, to give a list of species 

 collected by myself in the district extending from Faro, at Cape St. 

 Mary's in Algarve, to Carthagena near Cape de Gatt in Murcia, which 

 includes the southwesternmost comer of the European continent.
