co-types. This was commonly the cnse with many of Gray^s 

 and GroukFs species, and the reduction to a single specimen 

 of each for use as a type will certainly tend to the simplifica- 

 tion of future work on the group. 



These lectotypes have been carefully selected after com- 

 parison with the original "descriptions and with the fine 

 figures given by Gould. 



In one or two cases the same specimens have already been 

 selected by me in previous papers, but it seems advisable, for 

 the sake of completeness, to repeat the selection here.
