Article XV.—ON REPTILES OF THE NEW MEXICAN TRIAS IN 
THE COPE COLLECTION. | 
By FRIEDRICH VoN HUENE. 
Some time ago Professor H. F. Osborn and Dr. W. D. Matthew sug- 
gested that I reéxamine the Triassic Cope Collection now in the possession 
of the American Museum of Natural History in New York. After having 
seen the collection I gladly consented to accept that honor and the collec- 
tion was accordingly forwarded to Tiibingen for this purpose. With the ex- 
ception of one skull the remains are very fragmentary and in some cases it 
is hardly possible to know which specimens are Cope’s types and which 
ones of the others belong with them. As several skeletons of Phytosaurs 
have been found in Wyoming and New Mexico during the last few years 
and have not yet been described it is necessary to be very careful in de- 
scribing single scattered Phytosaurian bones. Therefore I shall only rede- 
scribe and figure Cope’s type specimens and bones surely belonging with 
them. At the present time only the describer of Prof. Williston’s new skele- 
tons would be able to do more.

1. Typothorax coccinarum Cope. 
Femur: The femur (Fig. 1), 22 cm. in length, most nearly resembles 
that of Thecodontosaurus antiquus. The main difference is the extreme 
thickening of the distal end. The trochanter quartus is very much more 
prominent than in any other known Pseudosuchian or Phytosaur, but it 
makes the characteristic angle always seen in the feeble Phytosaurian tro- 
chanter. The proximal end is not quite so broad as in many Phytosaurs; 
in this respect it more nearly resembles Pseudosuchians; it is also not so 
flat from the inner side as in many Phytosaurs. The trochanter minor is 
rather strongly developed, but lateral to it there is a groove as in many 
Phytosaurs, only smaller. Even a trochanter major is developed in this 
femur, but not quite so much as in Thecodontosaurus. The distal half 
of the bone is not so much curved (Fig. 1c) as is usual in Phytosaurs, but the 
turning of the distal extremity is about the same as in other, Phytosaurs. 
This part of the femur is not only very thick but also extraordinarily broad.
