meet. On its ventral surface the hinder part of the basihyal is 

 concave, the concavity being bounded on either side by a -marked, 

 oblique marginal ridge, these two ridges meeting to coalesce with 

 tlie urohyal {u), which is sliort and straight. 



The entoglossum (e) has its anterior parts rather slender, and its 

 posterior parts greatly expanded transversely. The anterior part 

 o£ each entoglossal has its dorsal margin slightly concave. Its 

 ventral margin develops a marked anterior lateral process (al), 

 separated by a marked concavity froui (pi) the posterior lateral 

 process. The posterior half of each entoglossal is greatly expanded, 

 and its surface, which looks outward and downward, is strongly 

 concave. Its dorsal margin is convex and rounded, but shows no 

 marked dorsal lateral process. 



The hxjpohranehials are rather short and stout compared with 

 those of Nestor, but they are mainly remarkable for being deeply 

 grooved antero-posteriorly on their dorsal surface ; they are very 

 slightly curved. 



The ceratobranchials are extremely short bones. 



My hope is to be able on some future occasion to describe certain 

 other Psittacine hyoids.
