NORTH HAVEN SERIES OF PENOBSCOT BAY. 
A characteristic Eosilurian fauna has been reported by Messrs. W. W. 
Dodge and Charles E. Beecher from the island of North Haven. 1 The 
rocks in which the fossils occur are described as dark bluish-gray, 
indurated shales, slightly calcareous at places, sometimes with calca- 
reous nodules; red shale with nodules of white limestone; conglom- 
erate sandstones, with dikes, porphyrite, and ash beds associated. 
The list of species was prepared by C. E. Beecher, who described the 
majority of the specimens as "too fragmentary and poorly preserved 
for accurate description or determination. " The list given is as follows, 
the letters indicating separate localities, which are indicated on a map 
in the original article: 2 
1. Monograptus clintonensis Hall, g. 
2. Ccenostroma sp. , c. 
3. Streptelasma calyculum Hall, g, c. 
4. Chonophyllum niagarense Hall, d.
