228 OLDER MESOZOIC FLORAS OF UNITED STATES. 
made in the red shales bearing the tracks so celebrated in that locality, 
and under the guidance of Mr. T. M. Stoughton we visited all the impor- 
tant places from which specimens of interest had been taken. We saw 
in these beds nothing that could be called vegetable, and it seems very 
doubtful whether any plants either grew or were ever transported by 
any agency into the riparian clays in which the Brontotheria and other 
saurians left their footprints in such profusion. 
Special attention was paid on this excursion to the form called Den- 
drophycus triassicus Newb. The original of one of the specimens fig- 
ured by Dr. Newberry‘ was seen at the museum of Yale University, 
the other? was examined at the museum of the Wesleyan University. 
Two other good specimens were afterwards secured at the Portland 
quarries by Mr. John H. Sage, of Portland, and generously donated 
by him to the National Museum. The finest specimens, however, are 
those at the Wesleyan University, also from the Portland quarry. 
Through the courtesy of Prof. W. N. Rice, of that institution, per- 
mission was obtained to have these speciniens photographed, and Mr. 
De Lancey W. Gill, then chief of the division of illustrations of the 
United States Geological Survey, kindly undertook to visit Middle- 
town in November and attend to the photographing of these speci- 
mens. Pl. XXXV, Fig. 1, represents one of these views. Although 
this differs considerably from the specimens figured by Dr. Newberry, 
coming as they do from the same quarry, it is to be supposed that they 
represent one species, and it, may be assumed that the specimens fig- 
ured by Dr. Newberry show the lower portion of the frond and did 
not contain those higher and finer lines so beautifully shown in the 
specimen at the Wesleyan University. These, therefore, will also be 
treated as belonging to D. triassicus. 
I may add that at Amherst several specimens of Dendrophycus from 
the Portland quarry, and, perhaps, from other points, were seen by 
us. They were labeled, apparently in the handwriting of Dr. Edward , 
Hitchcock, ‘“‘Aroid plants.” This is of special interest as showing 
that Dr. Hitchcock supposed them to be of vegetable origin. 
At the Washington meeting of the Geological Society of America 
in December, 1890, Prof. W. M. Davis and Mr. S. Ward Loper read a 
joint paper giving the results of their work in the Connecticut Valley.® 
The first part of this paper, by Professor Davis, is devoted to the 
discussion of his theory of the formation of the ‘‘trap” and the general 
stratigraphy of the Triassic formation in the Connecticut Valley. The 
second part, by Mr. Loper, treats of the fossils. It gives an enumera- 
tion of the fossil fishes and fossil plants found by him and their strati- 
graphical position, showing those that are confined to the anterior and
