120 HAY—VERTEBRATES OF CARBONIFEROUS AGE. [March 16, 
of Mr. Daniels’ collection, is occupied by a row of closely set 
sharp teeth. The branchiostegals are short and broad, the number 
not determinable. The mouth was large, the eyes large and placed 
near the end of the head. 
In case it shall be proved that the specimens described above be- 
long to a species distinct from that of Dr. Newberry, I suggest that 
they be called Elonichthys hypsilepis, with the large specimen of the 
Daniels collection as type, that in Columbia University as co-type. 
It seems highly probable that the fish mentioned by Newberry and 
Worthen in volume iv of the Geological Survey of Illinois, p. 348, 
1870, under the name Ambdlypterus macropterus ? Agassiz, may in 
reality have belonged to the same species as those herein described. 
It is regarded by Mr. A. S. Woodward as being an E/onichthys.

In the collection belonging to Mr. Daniels there is a split nodule 
from Mazon creek, which contains the remains of a specimen of 
Amphibamus grandiceps Cope. The fossil has been somewhat 
damaged by fractures and a small portion is missing. Further- 
more, as in the case of the original, the bones have been replaced 
by a soft white mineral, so that it has been found necessary in : 
places to remove this and take wax impressions. Notwithstanding 
the lack of perfection in the fossil, it presents so many interesting 
features that it seems desirable that it shall be described ; especi- 
ally since it is, so far as I am aware, the only specimen of the 
species which has been found since the discovery of the original. 
The entire length of this ancient salamander is 62 mm. The 
head is 15 mm. long and has a width almost exactly the same. The 
tail of the animal has been short, not exceeding probably 12 mm. 
Prof. Cope has represented the hinder limbs and portions of the 
anterior limbs. The whole hinder limb has had a length of 17 
mm.; the fore limb, so far as I can determine, a length of 13 mm.
