Résel. Even consenting to the opinion that all forms of Amebe 
may eventually be shown to be transitory phases of the same 
species, it does not render the determinations of Ehrenberg and 
his followers, in regard to A. princeps and A. diffluens, any the 
less incorrect. 
Arriving at the conclusion that the common large Amba, 
usually assigned to A. princeps is the same as the Proteus of 
Rosel, the question arises as to its appropriate name. Of the 
specific names employed for the little Proteus, that of “ Chaos” is 
the oldest, but appears to me less appropriate than that of “ Pro- 
teus,” applied afterwards. As the latter cannot be used in its 
generic sense, it might be aecepted in its specific application so as 
to perpetuate the name given to the animal by Rosel, its discov- 
erer. While, therefore, in strict conformity with the rules of 
zoological nomenclature, the little Proteus of Rösel, the Proteus 
diffluens of Müller, and the Ameba princeps of Ehrenberg, would 
be called Amba chaos, I would suggest that it should be called 
Ameba proteus.

Monveiro’s ANGOLA AND THE River Conco1—Now that Mr. 
Stanley has discovered the source of the Conyo, and crossed the 
continent to the Coast of Angola, one will turn to the present 
book for the excellent account it gives of a region so little known. 
The country described by the author lies between the River Zaire 
or: Congo and Mosammedes or Little Fish bay, comprising ten 
degrees of latitude. In this region, an interesting and rich part 
of tropical Africa, Mr. Monteiro lived and journeyed for many 
years. How the lowland country of the Angola coast may strike 
the stranger, and how the traveler journeys through its unique — @ 
scenery, may be ascertained by a glance at the view here given. 
A number of similar full-page engravings adorn the book, which 
is full of interesting information regarding the country and its 
people, their manners and. customs, and the 
upon them. All books of this sort sooner or later exhaust the 
human features of the country, and we are then regaled with 1n- 
teresting notes regarding the animals and plants, many of them s° 
strange and striking. Some of the characteristic insects are rP
