incubation described. C. Horne, tom. cit. pp. 241-243. 
Ithynchaceros ( Tockus) deckeni is described and figured as a new species 
from East Africa, dilfering from the small allied species by being darker and 
blacker above, and having the wing-coverts not so much spotted. The sides 
of the head, the neck, middle line of the back, and lower surface are white.

A paper showing a vast amount of research and accurate 
knowledge, and undertaken partly with the view of testing the 
practical working of the British Association code of rules for 
zoological nomenclature; for the author thinks that the founda- 
tion of a correct system cannot be laid until the whole of the 
species described by Linnaeus and Gmelin have been identified 
or disposed of. Of the 22 Linnaean species of Cuculus, 3 belong 
to other families, and 11 of the remaining 19 have been more or 
less satisfactorily identified, leaving 8 undetermined. Of these, 
2 seem to be beyond hope at present ; but the names of the last 
6 can, it is shown, be referred without much fear of error to the 
species for which they were intended. The 2 Linnaean species 
of Cvotophaga are identical. Gmelin named 24 species and 10 
varieties of Cuculus in addition to those given by Linnaeus, 
besides 2 species which belong to other families, 2 which really 
are Cuckoos though placed in other genera, and 1 Crotophaga. 
Of these 29 only 9 can, from one cause or another, retain 
Gmelin^s names. To all this patient investigation follows what 
is modestly called a sketch of the genus Eudynamis ; but it is 
a sketch of very elaborate character, for the synonyms of each 
of the 9 species recognized by the author, and in most cases suf- 
ficient diagnoses, are given, and Eudynamis I'ansomi, Bp. (Consp. 
Av. i. p. 101) is figured.
