It would seem that Professor Furbringer saw more Gull than 

 Plover in the Sheathbills, and had underestimated the signifi- 

 cance of the characters presented on their part, inasmuch as he 

 lias only awarded them family rank. 



The following year Cope 1 published his 'Synopsis of the Fami- 

 lies of Vertebrata,' and in his arrangement of Aves sets forth the 

 position of the Sheathbills as follows : —

The Laridte and their supposed allies he places in another 

 suborder of the Euornithes, viz., the Cecomorphae. 



It will be seen that Cope's suborder Grallae with its twelve 

 families nearly corresponds to Stejneger's order Grallae with its 

 five superfamilies divided into its seventeen families. Cope here 

 revived the opinions of those who believed that Chionis stood 

 most nearly related to the 'Thinocoridaa,' and yet showing too 

 that it was more Plover than Gull.
