stretching- from the Falls to St. David's. This must l>e dis-

David's. Dr. ScovelTs observations were made in 1886. He 
was led to the study as a sequel to extended investigations in 
the old channels of the Wabash and other streams which pre- 
ceded it, in Vigo county, Indiana. The old Niagara channel 
here referred to was "a little more than a mile wide" and its 
presence is indicated by wells sunk in the sand which now fills it. 
The villrige of Clifton, on the Canadian side, lies on the east of it. 
''The rock, which at Clifton Station rises 150 feet above the 
brink of the falls, represents the east bank of the old river."

REVIEW OP RECENT GEOLOGICAL LITERATURE. 
BecliercJies sur les Poigsons Paleozoiques de Belgiquc—Poissons du Famen- 
nieu par M. Lohest. Analyse par J. Fraipont. 
Until recently the Devonian strata of Belgium have been supposed al- 
most entirely destitute of ichthyic remains. During the last live years, 
however, M. Max Lohest, assistant professor of geology in the University 
of Liege, has managed to obtain from these same strata a very liberal col- 
lection of fossil ganoid fishes. The descriptions of tiiese fossils and the 
conclusions to be drawn from their discovery and character form the sub- 
gact of an interesting m3aioir recently issued by the Geological Society of 
Belgium. 
M. Lohest describes ten new species of ganoid fishes, one species repre- 
senting at the same time a new genus. In the memoir ten carefully pre- 
pared plates illustrate the new species and the richness of M. Lohest's 
discoveries is apparent when we note that all the (Belgic) species 
previously known are figured upon a single plate accompanying— the 
eleventh. Many years ago, Agassiz, in his famous study of the fossil fishes 
of central Europe, happened upon a few imperfect, large, thin scales. 
Upon this imperfect and scant material he nevertheless ventured to base 
the genus Phylhleplx. M. Lohest has discovered material by which he ia 
able not only to confirm the insight of his great predecessor, but also to 
enlarge the genus by the addition of two new species. 
A new genus of Lepidosteids is also described — Pentagonolepis—vihxch. 
offers a new type of ganoid scales. Toe scales are pentagonal and 
may be c nsidered as showing a transitional phase between purely cy- 
cloidal and purely ganoidal forms. 
As a result of his investigations and a comparative study of the Devon- 
ian of Mesiern Europe, M. Lohest concludes that the Belgic beds belong
