[This paper is a Hat, accompanied with descriptions, of 

 the Diptera found in the island of St. Vincent, by Mr. H. 

 H. Smith, the well-known American entomologist, who 

 was sent to the islands by F. D. Godman, Esq., F.R.S., 

 to assist the Committee in its investigations. Some 

 general remarks by the Author will be found at the end 

 of the paper. A second memoir, treating of the Diptera 

 of the neighbouring island of Grenada, will, it is hoped, 

 be almost immediately ready for publication, the present 

 instahneut having been in the hands of the Committee 

 for upwards of two years. — D. S.]
