240 MR. A. THOMSON’S REPORT ON THE InsucT-HousE. [Feb. 18, 
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 
the urohyal (u), which is short and straight. 
The entoglossum (e) has its anterior parts rather slender, and its 
posterior parts greatly expanded transversely. The anterior part 
of each entoglossal has its dorsal margin slightly concave. Its 
ventral margin develops a marked anterior lateral process (al), 
separated by a marked concavity from (pl) 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 hypobranchials 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.
