near which there are impressions of two glands, or they may be 
the posterior ends of the oviducts, as was suggested for the 
Yale specimens. Like the Yale specimens, the cesophagus is 
displaced and partially obscured. The creatures undoubtedly 
fed on small plants and animals, much as do our recent sala- 
manders. The alimentary tract is preserved fully extended.

It was very gratifying to discover among the remains loaned 
the writer by the Yale Museum other specimens exhibiting 
characters of the Branchiosauria, for our knowledge of this 
order of Amphibia is as yet very incomplete in North America. 
The specimen represents by far the largest of the group dis- 
covered on this continent. It is more than twice as long as 
the specimen of Hwmicrerpeton parvum and fully one-third 
longer than Micrerpeton caudatum. It is, however, distinctly 
a branchiosaurian. The ordinal characters are discovered in 
the heavy, straight ribs, attached to the transverse process of 
the centrum; in the low degree of development of the ver- 
tebree; in the structure of the skull and the ventral armature, 
and in the degree of ossification of the limb bones. 
It may be generically separated from other known Branchio- 
sauria found in North America by the great length of the dor- 
sal region, and by the elongate tail with its well-developed
