8. In the year 1850, Jones proposed a heterotypical genus (say)

 monotypical genera (say) Hcterognomon type viridana (p. i), and 

 Pandeinis type atrana (p. 2). 



In i860, Brown cited viridana as the type of Tortrix, Jones.

Nov. 26th, 1896. 



Present circumstances preventing my giving to the questions 

 the special answers desired without unduly delaying the accom- 

 panying documents, I can only say that I agree in general with the 

 views expressed by Lord Walsingham, except as they are opposed 

 to the code of rules formulated by the American Ornithologists' 

 Union, to which as a via media I have already given my adhesion. 

 The latter circumstance prevents my further indefinite pledge, but I 

 can hardly doubt that I shall be able to agree with the general con- 

 sensus when I know what it is.
