H. Smith did think O. heteOphyHa hybrid although
1t had stated that the early form OF O. phetcs re-
sembled IL. Dr. Lcdy also described an extraordinary
growth Of mushrooms recently observed by him. The
ady iual plants together formed Of "a inches III
one direction, and n in another.
Dr. Chapman exhibited the brain OF Manaee the frat
that had ever been obtained intact. He pointed out
some important differences from the specimen figured by
Dr. Murie Prof Cope spoke Of some vertebrate remains
obtained from a cave explored by Mr.. Wheatey There
apparently three species Of snakes and two OF tur-
ties One the snakes appears he allied to the recent
fern Of black snake, hut had a much more produced
snout. II referred to the genus BdSc0nion. DI.
Harrison Allen made some remarks on the notation Of
ribs Inasmuch the false ribs. II produced, woud BE-

by The specimens exhibited.
Prof Cope also called attention TO certain points OF
