600 HERE, C. BKUNNER ON THE ORTHOPTEBA OF [June 20, 



very considerable difference between the Faunas of these two 

 islands so far as Orthojitera are concerned, but I think the 

 apparent great diversity may probably be found to be due to 

 some extent to differences in the collecting that has been carried 

 on in the two islands. The same collector, Mr. H. H. Smith, 

 formed the collection from both islands, but it is understood 

 that the one he procured while in St. Viucent is more complete 

 than that which he formed in Grenada. If so, on the hypothesis 

 that other of the St. A'incent species remain to be fouud in 

 Grenada, the difference between the two islands may possibly be 

 found to consist of the fact that Grenada has a richer Orthopterous 

 fauna than St. Vincent possesses. Whether this really be the 

 case, and if so, whether it be due to the much greater proximity 

 of Grenada to the mainland cannot, however, be satisfactorily 

 discussed until the data shall be much more complete than they 

 are at present.
