844 The American Naturalist. [September, 
came the irruption of the Arnauts or Albanians. The result is, that 
at the present time the old Hellenic blood has entirely disappeared, 
and all the people of the peninsula are more or less mixed. About 
90,000, chiefly at or near Corinth, and on the Ægean coast, still speak 
Albanian, but all the rest of the inhabitants use modern Greek. 
Dr. Hickson has published an interesting book, giving the results of 
his residence, for nearly a year, upon a small island off the extreme 
north coast of Celebes. During this stay he made excursions to the 
northern part of the main island, and also to Nangir, Nanusa, and 
Talant, small groups between Celebes and the Philippines. About half 
of the book concerns the northern part of Celebes, especially treating 
of the mythology and customs of the natives. 
The greater part of the island erupted in 1885 in the Tonga group 
(Falcon Id.) has disappeared, and the existing island isa shelving bank 
to the northeast of it. The volcanic debris may now form a platform 
upon which a coral reef, and ultimately an atoll, may be built up. 
GEOLOGY AND PALEONTOLOGY. 
Newberry's Paleozoic Fishes of North America.'—In this 
volume we have collected descriptions of the fishes of the Paleozoic 
formations of North America, which have been discovered by Pro- 
fessor Newberry since the publication of his report of the geological 
survey of Ohio, with a few others. The species there described, as 
well as those described in the report of the geological survey of Illinois, 
by himself, Mr. St. John, and Prof. Worthen are only enumerated ; 
and those described from the Permian beds of Illinois and Texas, by 
the present reviewer, are not mentioned. Add to this the fact that no 
bibliographic references appear, and we see that Professor Newberry 
has not intended this work to have the characteristics of a complete 
monograph. It is therefore that we welcome it as a collection of 
descriptions of numerous remarkable forms of early fish-life discovered 
by the author, which will greatly advance our knowledge on the sub- 
ject. is branch of paleontology is an important one, representing 
as it does our knowledge of the earliest-known Vertebrata, and includ- 
ing asit must the ancestral types of all later forms.
