Some of the characteristic features presented by the skeletons of two 
forms of the sub-class Odontornithes, Ichthyornis dispar and Hesper- 
ornis regalis, are described in this paper, and as a result of the examina- 
tion of nearly complete skeletons of both forms the following division is 
made of the Odontornithes or Aves Dentatae: — 
A. Teeth in sockets, vertebrae biconcave, sternum with keel, wings 
well developed. Order, Ichthyornithes. 
B. Teeth in grooves, vertebrae as in recent birds, sternum without 
keel, wings rudimentary. Order, Odontolc^. 
The author has in preparation full descriptions with plates of all the 
known species of Odontornithes, a work which cannot fail to be 
of the highest interest. In the meantime, figures are given of the 
left lower jaw and one of a cervical vertebra of Ichthyornis dispar ^ 
and the left lower jaw, a tooth, and a dorsal vertebra of Hesperornis 
regalis,

A translation of the portion relating to ornithology of Herr Leybold’s

This paper appears to be based entirely upon that recently published 
by Mr. Sclater in the Zoological Society’s Transactions. The chief cha- 
racteristics of the Ourassows are concisely given, with special reference 
to the diversity subsisting in a greater or less degree between the sexes 
of the dijfferent species.
