Devonian.—In the transactions of the New York Academy of Sci- 
ence, Prof. Newberry publishes a brief description of a series of fossil 
fish from the lenticular calcareous concretions in the top of the Erie 
shale in the Valley of the Cuyahoga, near Cleveland, Ohio. 
1. Cladodus n.sp., a shark six feet or more in length, and witha 
diameter of body of about eight inches. 
2. Actinophorus, nov. gen., a long slender ganoid, and Actnophorus 
clarkii, n. sp., a slender fish about two feet in length by two and a half 
inches diameter at the pectoral fins. 
3- Dinichthys curtus; of medium size. 
4. Dinichthys terrelli (?) Newb. 
5. Dinichthys tuberculatus, n. sp. 
At a meeting of the New York Academy of Sciences, April 16, 
1888, Professor Newberry described at length a species of Rhizodus 
found in the mountain limestone at Alton, Ill., which evidently repre- 
sents a species of Rhizodus much like Æ. Aibdberti Ag., which he 
named &. anceps. 
Mesozoic.—Mr. R. Lydekker describes and figures in the Sep- 
tember issue of the Geological Magazine an imperfect left pectoral . 
paddle of /chthyosaurus intermedius showing traces of the integuments. 
Such specimens are very rare. 
The British Museum has recently acquired a remarkably well-pre- 
served female specimen of Rhinobatus bugesiacus, the gigantic ray 
from the lithographic shales of Bavaria. It is about five feet long, 
and complete in all important respects.— Geol. Mag., Sept., 1889. 
M. A. F. Mariori describes De“iostrobus sternbergit, a new genus of 
Tertiary Coniferæ.—Ann. Sct. Geologiques, 1889. 
Mr. J. Carter, in describing Palega mecoyi (Geol. Mag., May, 
1889) states that up to date scarcely thirty fossil species of Isopoda 
are known to science. The new species occurs in the Cambridge 
upper greensand. 
A new form of Pinna, another of Prodromus, and the echinid 
Eodiadema granulata, are added to the fossils of the Lias by Mr. E. 
Wilson and W. D. Crick.— Geol. Mag., July, 1889. 
According to Petermann’s Mitteilungen, Prof. A. Wichmann found 
upon the small island of Saniamo, off the coast of Timor, numerous 
mud volcanoes; and on that of Rotti, at the southwest end of Timor, 
he discovered, in two mud volcanoes, some ammonites and belemnites, 
the first Jurassic fossils yet found in the archipelago.
