The British Museum possesses 429 out of the 612 species 

 which are known to exist in the different European collections. 

 Many of those which are wanting are inhabitants of our own pos- 

 sessions, or places with which we have a considerable trade ; it is 

 therefore to be hoped, now that the desiderata are known, that we 

 shall soon be able greatly to reduce their number, and also, doubt- 

 less, add to the species already described.
