376 Recently published Ornithological Works. 
which borders the shores of the Red Sea between Suakira and 
Massowah. 
In the first volume of the present work is given a narra¬ 
tive of the expedition, with some chapters of advice to 
hunters and sportsmen who may wish to resort to this easily 
accessible and thoroughly wild district. An excellent map 
is added. 
The second volume is devoted to an account of the mam¬ 
mals and birds of the district, and forms a useful handbook 
for those who are acquainted with German. Of birds 416 
species are enumerated. Philothamna minor (p. 182) and 
Batis orientalis (p. 194) are figured and described as new, 
we believe, for the first time, the latter having been previously 
referred to Platystira pririt and P. senegalensis.

[A Monograph of the Bucerotidse, or Family of the Hornbills. By D. 
G. Elliot, F.R.S.E., F.L.S., &c. Part 1, small folio, 1877. Published 
by the Author.] 
Mr. D. G. Elliot has commenced the issue of another of 
his beautifully illustrated monographs, and has chosen on 
this occasion the singular group of Hornbills for his subject. 
The six plates in the first number are excellently drawn by 
Keulemans, and coloured well. They represent the follow¬ 
ing species according to Mr. Elliot's nomenclature :— 
Rhinoplax vigil. Anorrhinus albocristatus. 
Sphagolobus atratus. Bycanistes subcylindricus. 
Cranorrhinus waldeni. Tockus monteiri. 
We hope Mr. Elliot will not carry his subdivision of the 
genera of the Bucerotidse to an extreme point, and that he 
will not insist on adopting more antiquated names than he 
can help. Does any ornithologist (unless he has just referred 
to Mr. Elliot's work) know what Rhinoplax vigil is ? and must 
we necessarily adopt that specific name? As regards the 
species described and figured by ft. R. Forster himself in his 
e Zoologica Indica,' there can be no question; and his names 
have always been in use; but whether we are obliged to em¬ 
ploy the terms assigned to the Planches Enluminees, Edwards's
