Packard.] 256 [December 18, 
called by the Danes “ Sea Monk.” It has been found driven ashore 
on the coast of Denmark. He had also seen, by the kindness of 
Prof. Steenstrup, a large cuttlefish at the Copenhagen Museum just 
brought in from Iceland. Its longer arms measured about twelve 
feet in length. 
Dr. Packard exhibited drawings and gave a brief account 
of a new species of Bopyrus found by Dr. Gissler in the bran- 
chial cavity of a Hypolite found in New York harbor. It 
was allied to the Bopyrus squillarum of Europe, but differed 
in some important particulars. The minute male was found 
with its head under the basal gills of the female. 
He also noticed briefly the development of Gelasimus pug- 
nax Smith, from Ft. Macon, N. C. For the identification of 
this species he was indebted to Mr. 8. I. Smith. He had 
studied ‘the embryo just previous to hatching. It seemed to 
agree, as regards the end of the abdomen, with that of Se- 
sarma, and was of the usual zoéa form previous to the first 
moult, particularly as regarded the anterior claws. He 
thought the differences homes these feet were produced 
comparatively late in larval life. 
Dr. Brewer announced the gift of a rare goose (Anser 
JSrontalis), from Gardner Brewer, Esq. 
The donation of a porpoise by Capt. Atwood was also 
, announced.

ery, geology, etc. Dr. Curtis also presented a number of 
specimens from that region.
