Dear Newton
Mr. Gurney1 has sent me some notes on the Spizaeti we examined together, which I have returned & have asked him to send to you for insertion2 along with my note in the next "Ibis".3
I return you Blyth's4 note with thanks. I omitted to look over his lengthy notes as I ought to have done. I do not think that a bird's being in the Calcutta Museum5 as from Malacca, is always sufficient proof that [2] it really came from there. The name supereus[?] Horsf. I maintain must be sunk, the description being quite unrecognisable even though the types are in the E[ast]. I[ndia]. Museum.6
With regard to Huxley's 'Classification'7 I cannot think that such a heterogeneous group as his Desmognathae8, for instance, will ever be adopted by Ornithologists.
What I wish Huxley would do is to try and trace out the genealogy of Birds, and then [3] leave us to arrange our own groups, for it is evident the same genealogical tree can be divided many ways into groups, of various degrees of convenience and homogeneity.
Embryology and anatomy sh[oul]d mark out for us the lines of affinity, not mass birds into great groups, which are almost sure to be at least as "irrational and unsatisfactory" — as schemes founded on external characters.
Yours very faithfully | Alfred R. Wallace [signature]

Of these three arrangements of the above related groups, each might agree best with certain characters, but none could be said to be absolutely truer than the other. We should therefore choose the most convenient & that which agreed best with external characters.
