A species of the genus rather larger than a pigeon, of which more than forty specimens 

 have been found in various localities in Kansas, all apparently from the same geological horizon 

 in the middle Cretaceous. These are preserved in the Museum of Yale College,

This species was nearly as lai-ge as a swan. The remains by which it is represented were 

 found in the middle marl bed, of upper Cretaceous age, at Birmingham, New Jersey, and ai'e 

 now in the Museum of Yale College.

A bird about as large as a curlew. The remains representing it were discovered in the 

 green-sand of the upper Cretaceous, near Hornerstown, New Jersey, and are preserved in the 

 collection at Yale College.

From the same formation and locality as the last; of smaller size, being intermediate 

 between the other two species of the genus. The specimens upon which this species is based 

 arc preserved in the Yale College Museum.

The first fossil bird of North America appears to have been noted by Dr. iMorton in 1834, 

 as that of a snipe-like species. The specimen, consisting of a femur imperfect at the upper 

 extremity, was presented by S. W. Conrad to Dr. Harlan, who remarks that "the bone 

 appears to be perfectly mineralized." It was found near Arneytown, New Jersey, in the lower 

 marl bed of the Cretaceous formation. This same specimen (which meanwhile had been 

 generally regarded as of a recent species, notwithstanding its condition and the position in which
