[Hitchcock. 
foot of Polemarclms may be seen on these slabs. It has four toes, 
and is not unlike the fore foot of Anisichnus. The Massachusetts 
locality has not yet supplied us with so much information about 
this most interesting animal as this slab from New Jersey. 
This quarry has yielded also a small species of Otozoum. This is 
probably the same with an impression seen by me in situ on the 
Pennsylvania side of the Delaware river in 1868 and referred to 
Cheirotherium 1 . Except for the absence of the fifth toe, the simi- 
larity of our new species to the Cheirotherium Barthii of Europe 
is very striking. They are identical in size. The front foot is better 
shown than the hind one in the specimens, and is unlike the corre- 
sponding part of the Otozoum Moodii. The suppression of one 
toe gives us a trifid foot very ornithic in aspect. Another relief- 
track is that of a three-toed foot having the outer toes very much 
larger and longer than the others, such as is exemplified in the Hes- 
perornis. Possibly this may lead us to the discovery of a true 
bird track in the Trias. 
Prof. I. C. Russell has found tracks in Plainfield and near Boon- 
ton. Among his drawings from the latter locality I recognize Bron- 
tozoum approximatum and Grallator formosus. 
LOCALITY AT YORK, PENNSYLVANIA. 
Mr. A. Wanner of York, Pa., sent to the National Museum at 
Washington a slab showing impressions of Anomcepus gro.cillimus , 
Brontozoum Sillimanium and A7iisiehnus gracilis. He exhibited 
drawings of this slab and of other interesting fossils at the Cleve- 
land meeting of the A. A. A. S. in August, 1888. 
DESCRIPTIONS OF NEW SPECIES. 
One of the best marked forms requiring description may be re- 
ferred to the Apatichnus. The Mt. Holyoke Museum purchased 
a slab from Turner’s Falls showing eight tracks of an animal al- 
lied to Anomcepus as respects the general form of the hind foot, the 
heel and the front foot, but having a fourth toe. A study of the 
various ichnites leads me to refer it to Apatichnus and the spec- 
imens enable us to understand better the intimate relationship of 
the two genera. The slab is 6ft. 3in. long, 2ft. 4in. wide, with eight 
tracks of the hind feet, two of the front feet and rather imperfect 
impressions of the long heel. The row is interrupted by a break in
