The scope and object of this work has been described in the 
Record for 1864, vol. i. p. 133. The present volume contains 
the families Heteropygii, Cyprinidce, Gonorhynchulce, Hyodontida^ 
Osteoglossidce, Clupeidce^ Chirocentrida 2 , AlepocephalidcBj Notopte- 
ridcB, and Halosaurida. The number of species treated of 
amounts to 1281, many (407) being so imperfectly known that 
they are mentioned by name only. Cuvier and Valenciennes 
enumerated 673 species in the corresponding parts of the His- 
toire naturelle des l^oissons,^ 318 of this number being either 
nominal or very imperfectly described.

The author gives an account of the collection of freshwater 
fishes made on the Zambeze during his expedition in the years 
1842 to 1848. The species were enumerated by him in the 
' Monatsberichten der Berliner Akademie,^ 1852 & 1855, and are 
now described in detail, and illustrated by excellent figures. 
Remarks on the structure of internal organs are added to most 
of them. He treats altogether of fifty-one species, four of which 
are found in the Island of Johanna, forty-seven in Mossambique, 
and forty-four in the Zambeze. lie remarks that four of the 
latter may be regarded as marine species, two extend to India, 
one is spread nearly over the whole of Africa, five are found in 
the Nile and West- African rivers, one in Guinea, whilst twenty- 
eight are peculiar to the system of the Zambeze. 
When we regard the scientific value of this most elaborate 
publication, it would appear almost trivial to indicate the slight 
modifications of those numbers which we might suggest, having 
a different opinion with regard to tlie validity of certain species. 
However, as tlie author has repeatedly and prominently stated 
that the great English expedition to the Zambeze regions has 
added only a single species to this part of the fauna, we think
