A popularly written summary of the chief peculiarities of the family, 
illustrated by a plate representing Megalcema asiatica. From the facts 
adduced relating to the distribution of the different members of the family, 
the author urges the probability of the derivative theory of species.

Another of the author^s valuable monographs. Of the 
numerous so-called genera into which the family has been split, 
he is content with five only, using the names of the rest, with half 
a dozen new ones, to indicate minor groups. These genera and 
groups are as follows: — (i) Ramphastos [lege Rhainphastus'], 
containing five divisions : (1) Rhamphasius with two species, (2) 
Burhynchus and (3) Tucanus with six each, (4) Rumphodryas 
[Rhamphodryas] with two species and three varieties of R. aridj 
and (5) Tucaius with one species — these last four names being 
apparently used for the first time; (ii) Pteroylossus, including (1) 
Pteroglossus proper with eleven species and three varieties of P. 
castanotis, (2) Grammarhynckus [lege Grammatorliynchus\ with 
three species, (3) Pyrosterna with five, and (4) Beauharnaisius and 
(5) Baillonius (a new name) each with one species — P. aldrovandi 
(Shaw) being a doubtful species ; (iii) Belenidera, comprising (1) 
Selenidera proper with five species, and (2) Piperivorus and (3) 
Ramphastoides [lege Rhamphastoides] (a new name) with one 
each ; (iv) Aulacorhamphus and (v) Andigena are each composed 
of two divisions, the former of (1) Aulacorhamphus proper with 
five and (2) Rhamphoxanthus with six species, and the latter of 
(1) Andigena proper with three species and (2) Rhamphomelas 
with two. Besides these Mr. Cassin enumerates some other de- 
scribed species of Rhamphastus, which he cannot determine. No 
species are described as new.
