_Ocydromus minor_ Hamilton (nec. Forbes) l.c.
This species is nearest allied to _sylvestris_ Scl., which has quite
erroneously been placed in the genus _Cabalus_ by Dr. Sharpe; _sylvestris_
will have to form the type of a new genus, but until the skull of _minor_
is known I prefer to leave the latter temporarily in _Ocydromus_.
The present species is known from two pelves, seven femora, six tibiae, and
five metatarsi, as well as the front portion of a sternum. The measurements
all show that _minor_ was a slightly larger form than _sylvestris_, but
owing to having a much shorter tibio-tarsus it must have been a much
stumpier bird.
