Show 240 MR. A. THOMSON^ REPORT ON THE INSECT-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 (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 clorscd 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. M y hope is to be able on some future occasion to describe certain other Psittacine hyoids. February 18, 1896. Prof. G. B. HOWES, F.Z.S., in the Chair.
