ment in the shallow bays, on the steep banks of the deeper thoroughfares, and 
in the sound from the Great Egg Harbor river to Cape Island. Algz occur in great 
abundance, parasitical on the common eel grass (Zostera marina), which is so 
extensively dispersed in the bays, and on the bars in the vicinity of Beesley’s 
Point, and which grows withsuch luxuriance as seriously to obstruct the passage 
of boats when the tide is out. I found Alga, growing on the oyster beds, on 
sand bars, mud flats, also on shells, sods, and such submerged ‘substances 
as afforded a resting place. 
The submerged portions of the ship Rhine, which went ashore last winter at 
Corson’s Inlet, are already literally covered with marine vegetation. 
From the want of a standard collection in the Academy, Iam unable at pre- 
sent, with my limited knowledge of the science, to determine satisfactorily 
many of the species. Among the specimens on the table will be found: 
Fucus vesiculosus, Linn. Very common. 
Ectocarpus littoralis, Lyng. 
Ceramium rubrum, Ag. MOB 7 = ens 
C. diaphanum, Ag. ¢ parasitic on Zostera Marina. 
Callithamnion polyspermum, Ag. 
Nemaleon 
Laurencia tenuissima, Grev. 
Polysiphonia, several species. 
Bryopsis plumosa, A 
Lyngbia 2 
Ulva latissima, Linn. 
Rhabdonia Baileyi, Harvey. 
Ulva compressa.

Dr. Leidy presented a paper from Prof. 8. F. Baird and Charles 
Girard, intended for publication in the Proceedings, on the ‘ Charac- 
teristics of some new Reptiles in the Museum of the Smithsonian Insti- 
Tee which was referred to Dr. Hallowell, Dr. Le Conte, and Dr. 
eidy. : 
Dr. Le Conte presented a paper, intended for publication in the Pro- 
ceedings, entitled “‘ Synopsis of the Scydmeenide of the United States.” 
Referred to Dr. Leidy, Dr. Fisher, and Dr, Zantzinger. 
Dr. Le Conte presented a second paper, also intended for publication, 
entitled “ An attempt at a Synopsis of the genus Geomys Raf.,” which 
was referred to Dr. Wilson, Mr. Cassin, and Dr. Woodhouse. 
Dr. Leidy called the attention of the Society to a fragment of a jaw 
containing two teeth of Tapirus Haysii. This species had been charac- 
terized by him at a previous meeting, from a single tooth presented by 
Dr. Hays to the Academy, and which at that time was the only portion 
known. The present specimen is from the Post Pleiocene, near Natchez, 
Miss., and was sent to Dr. Leidy by Mr. Wales.
