taxaspideæ

from The Century Dictionary.

• In ornithology, in Sundevall's system, the fifth cohort of scutelliplantar Passeres, consisting of a heterogeneous allocation of chiefly American genera, such as Thamnophilus, Formicarius, Pteroptochus, and their allies, to which are added the Madagascar genus Philepitta and the Australian Menura. Without the two last named, the group would correspond somewhat to the formicarioid Passeres.
