149. PHEGOPTERIS POLYPODIOIDES, Fée. 
“In ravines.” B. Both species are more or less abundant all along 
the coast, the latter more than the former. 
150. PELL@A (ALOSORA) GRACILIS, Hook. 
Not very common, but distributed in localities apparently along the 
coast? Mr. Butler found it “but upon one small rock which had 
fallen from the cliffs at Forteau; and on my last visit to F. I could not 
find even that.” Iam sure I have seen it more than once in my ex- 
peditions, but, unfamiliar with its small size and delicate texture, I have 
not collected and identified it.

152. CYSTOPTERIS MONTANA, Bernh. 
« Amour.”  B. 
153. ASPIDIUM SPINULOSUM, Swartz. 
Abundant everywhere along the coast and in the interior. 
154. ASPLENIUM FELIX-F@MINA, Bernh. 
On hillsides.” B. 
155. OSMUNDA CINNAMOMEA, Linn. 
Rare. I found several small specimens growing about the edges 
of a small pond at Bonne Espérance, August 11, and I believe found 
it in one or two other places near by. 
156. BOTRYCHIUM LUNARIA, Swartz. 
Very abundant in a few small spots at Bonne Espérance; found in 
dry places distributed sparingly along a limited line of coast.

Several other species were collected this season, but I have been un- 
able to secure names for them as yet. 
ON THE BLACK NODULES OR SO-CALLED INCLUSIONS IN THE 
MAINE GRANITES. 
BY GEORGE P. MERRILL. 
Accompanying the samples of granite collected by agents in the employ 
of the building-stone department of the tenth census, there were re- 
ceived at the museum from various States, but principally from Maine, 
numerous specimens of the dark nodules or socalled inclusions so abun- 
dant in many of the ganites of that region. I have prepared thin sec-
