different groups of animals. [This view is opposed by 0. S. Minot, Science, 
i. p. 525.]

This work, it is to be feared, will not be of much real use to students 
of the West African fauna. Its author’s chief object seems to have been 
to accumulate as large a number of genera and species as possible, and he 
may be congratulated on his success in this direction, as he mentions 
no less than 66 families, 126 genera, and 219 species, a result attained by 
the recognition, for the most trivial reasons, of all the good or bad 
genera and species described from the district, aud also by the founda- 
tion of others on the different races of domesticated species, and on 
slight varieties of wild ones [see Zool. Rec. xix. Mamm. p. 13]. Notes 
on the native names and comparative rarity of the species are appended ; 
and, in the cases where no- doubt can exist as to their correct identifica- 
tion, these may be of some service. Besides those mentioned last year, 
2 new species are indicated. [See Felis bouvieri ( Felidce ), ‘‘ Cuniculus ” 
senegalensis ( Leporidce ).]
