6 subfamilies. Pandion referred to Milvince. — Analytical tables of chars, of the gronps,

The classification is based chiefly on the characters afforded by the structure of the "super- 

 ciliary process of the lachrymal bone," whether rudimentary and not visible from the out- 

 side, or whether developing a superciliary shield. The author later very materially modified 

 his views, upon further consideration of the general osteological structure of the family (cf. 

 Bull. If. S. Geol. and Oeogr. Surv., 2d ser., Ko. 4, June 10, 1875, pp. 225-231, pU. xi-xviii).
