Well has Dr Hartman remarked, that the species of this group “are involved in 
almost inextricable confusion.” Our ignorance of the animal in most forms, combined 
with the fact that authors have described frequently from single specimens, or from 
series of two or three, entirely at present prevents one ascertaining the true specific 
limits. 
In the one or two instances where I have attempted ‘lumping,’ the results are due 
to a long series of specimens in which I have been unable to arrive at a definite break 
between the one ‘species’ and the other. 
The conclusions I have drawn are founded on Newcomb’s and Pfeiffer’s type 
specimens ; specimens compared with Gulick’s types; further a few of the types de- 
scribed by Mr Smith; and, finally, the specimens collected by Mr Perkins and a collec- 
tion formed by Mr Hutchison. 
All the species of this group are confined to the Island of Oahu.

Dixon was thoroughly binomial, as a reference to his work will show : his figures 
are good, and the only point that can be made against the utilization of his name is that 
it appeared in three words. This, probably, was a printer's error, or a slip, as other 
names in the same work are proper, and suitable descriptions are given.
