gratification to him to learn that Mr. Gould has produced a 
book which is not specially designed for the amusement of dilet¬ 
tanti, but, on the contrary, is intended to be of real service 
to the working ornithologist. The ‘ Handbook to the Birds of 
Australia'*, the publication of which we announced some 
/ months ago (Ibis, 1865, p. 239), has recently appeared; and 
we do not hesitate to declare that it is one of the most useful as 
well as one of the most important works on ornithology that 
has seen the light during the past year. It is most useful, since 
the bulk, to say nothing of the expense, of his previous labour 
on the same subject, the magnificent ‘ Birds of Australia/ places 
it out of the reach of most private persons; and it is most im¬ 
portant, because this very facility of using it is sure to give 
a powerful impulse to the study of ornithology among the 
flourishing communities who inhabit the southern outliers of the 
British empire. 
To review this book would be impossible for us at present; 
but, should time and space allow, we will return to its further 
consideration. Mr. Gould has, as it seems to us, very fairly 
fulfilled our words of promise to which we have but just re¬ 
ferred. We owe him our thanks, especially for carrying out 
rigidly the law of priority in nomenclature; and herein he sets 
a good example to many of our cotemporaries; for he is quite 
willing to disregard names conferred even by himself when con¬ 
vinced that they are but synonyms of those previously applied to 
the same species by other writers. We must, however, state that in 
some respects Mr. Gould fails to meet the requirements of science 
at the present day. In the work we are noticing he creates a 
not inconsiderable number of new genera, and this without 
defining their limits. The mania for genus-making, now un¬ 
fortunately so prevalent, appears to us, more likely than any¬ 
thing else, to put a check upon future biological investigations. 
But hitherto we believe that the worst offenders in this respect 
have usually been accustomed to give some rational definition 
of the new groups they propose to establish. Our author, we
