In comparing the number of accessions with those of other 

 Museums, it has to be remembered that the numbers here given 

 are those of the selected registered set, and that all duplicates 

 are eliminated before registration. From eight to fifteen adult 

 specimens of a species from any one locality are generally thought 

 sufficient to illustrate its characters, even when more are available, 

 and the enormous series of individuals absorbed by some Museums, 

 combined with the enumeration of all of them, duplicates or not, 

 make up totals on which no true comparison with the British 

 Museum numbers can be based. 



The same fact should be borne in mind by donors and col- 

 lectors, who may find that the number of specimens here credited 

 to them are less than the actual number originally sent.

Note. — The date following the sender's name indicates the 

 year when the first contribution came in from him. Many, 

 perhaps the majority, of the persons here enumerated continued 

 to send in collections over a long period of years.
