This useful publication consists of a masterly digest of M. 
Mallierbe^s great ^ Monograpbie des Picidees/ published at Metz 
between 1859 and 1862. Each species is fully described, re- 
ferences being made to the works in which it is figured (when such 
is the case), and its habitat stated. Excellent indices are also 
added. The Picidce are divided into three genera only — Picus, 
PicumnuSy and Jynw. Picus is made to contain four series 
(further separable into tribes which are unnamed) : — (1) Angus^ 
ticolleSy (2) Securirostres, (3) Ligonirostres, and (4) Nudinares, 
The first of these series is composed of 4 tribes and 35 species, 
the second of 8 tribes and 103 species, the third of 14 tribes 
and 80 species, and the fourth of 4 tribes and 36 species. 
These tribes are further subdivided into sections and smaller 
groups. The effect of all this is to leave the genus Picus with 
254 known species, besides 24 doubtful or spurious ones ; Pi- 
cumnus with 28, all pretty well determined ; and with 4, — 
a very different treatment of the family from that of most modern 
authors. We think it needless to indicate the precise limits of 
the smaller groups of species, or their relation to the too nu- 
merous so-called genera which have been lately instituted ; for 
the work is one which must be consulted by any one working at 
the family, and in its last pages contains a concise synopsis of 
their contents. Several new species are described; and some 
others receive new names in consequence of the author^s ar- 
rangement of them. The whole of this careful work is in Latin.

Picus canifrons is a new species from Northern China, belonging to the 
same group as P. auritus, h]yton, from Malacca, and P. kalcmsis, Swinhoe, 
from Pormosa, with the anterior part of the back white and tlic crown grey, 
broadly girt with black behind. Cf. Suudevall, Consp. Av. Picin. p. 20. 
Picus hedenhorgi is a new species from Kordofan and Sennaar, belonging to 
the same group as P. Wagler, with which it was confounded by 
Malherbe, but from which it differs by having the gastrajum slightly streaked 
with narrow dusky lines and by being larger. It is the P. ohsolctus of Sun- 
devall, QCfvers. K. V.-Akad. 1850, p. 131 (iicc Malherbe, nec Cabanis et 
Heine). Idem, op. cit. pp. 31, 32. 
Picus ruhidus is a new species from Venezuela, belonging to the same 
group as P. oleagineus, Lichtenstein, from Mexico, P. fumigatus, Latr. & d’Orb,, 
from Peru and Bolivia, and P. cahoti, Malh., from Central America. It is the 
Phloeoncrpcs rcichenhachi of Cabanis and Heine (nec Celcopicus reichenhachi, 
Malherbe). Idem, op. cit. p. .
