panic notch is shallow, with its outer border not so well pro- 
tected as in Branchiosaurus. 
The cervical vertebre are incomplete, but their number was 
four or five, as in Micrerpeton. The structure of the dorsal 
vertebre is also uncertain, although the shape can be dis- 
cerned. The vertebre are short and thick, very unlike the 
long, cylindrical vertebre of Cephalerpeton. The heavy trans- 
verse process is quite evident on the best preserved vertebre. 
This process recalls that described by Credner for the Saxony 
Branchiosauria. Several of the vertebre show the attach- 
ment of the ribs to this process. The ribs of the caudal region 
recall very strongly those of Branchiosaurus. They are quite 
heavy in the anterior caudal region and then diminish rather 
rapidly to the point where the tail is broken and lost. 
The ventral armature is represented by a patch of chevron 
rods twenty-one millimeters in length. The rods take a very 
peculiar form. They are short, crescentic bundles of fine rods, 
hair-like in appearance. In one of the bundles I count five 
smaller rods. The bundles are arranged in rows similar to 
the pattern so characteristic of the Carboniferous Amphibia, 
as described elsewhere. The patch of ventral armature pre- 
served belongs to the abdominal region, so nothing can be 
told of the gular and thoracic rods. A single row of the 
crescentic bundles measures 11 mm. 
Both scapulez are preserved in their entire form. They are 
quite different from those of any other genera. They resemble 
.a broad crescent with a posterior concavity and an anterior 
protuberance. The articular surface of both scapule is ob- 
scured. Vascular foramina occur near the base of both scapule. 
There are three of them in the right element, arranged in the 
form of an isosceles triangle. The morphology of these three 
foramina is uncertain. They have never before been ob- 
served among the Carboniferous Amphibia, and, so far as I 
am aware, they are entirely unknown among the higher ver- 
tebrates. 
The temnospondylous Amphibia of the Carboniferous and 
Permian possess, in the codssified scapula-coracoid, three fo- 
ramina, very similar to the present ones, but they are confined 
to the coracoidal region, and in the Branchiosauria the cora- 
coid, as identified by Credner, is a free element, although I 
have never been sure with regard to its identity among Ameri- 
can forms. Williston, in Trematops, has called these foram- 
ina the glenoid, supraglenoid and supracoracoid foramina
