Show 1371.] ON CERTAIN SPECIES OF TYRANNIDAE. 751 8. Remarks on the Species of the Genera Myiozetetes and Conopias, belonging to the family Tyrannicb_e. By P. L. SCLATER, M.A., Ph.D., F.R.S. [Eeceived November 28, 1871.] Mr. G. N. Lawrence, of New York, having kindly sent to me for examination some of the types of his newly described Tyrannidae, and thus given m e the opportunity of comparing them with the specimens in m y own collection, I have drawn up a few notes on the species of two allied genera, Myiozetetes and Conopias, which may, I trust, serve to assist others in the task of determining these difficult birds. First, as regards Myiozetetes *, Mr. Salvin and I, in some remarks on Myiozetetes granadensis (P. Z. S. 1867, p. 279), have proposed to divide the species of this genus allied to M. cayennensis as follows:- 1. M. guianensis. Species with a clearly defined white superciliary stripe. «'. Species with the primaries externally narrowly" bordered with rufous, and with the basal half of the inner webs of both primaries and secondaries broadly margined with pale rufous '2. M. texensis. 3. M. columbianus. 4. M. cayennensis. _ 5. M. similis. Species without a white superciliary stripe 6. M. granadensis. Species without rufous edgings to primaries, embracing four local forms, which require further-examination The examination of the specimens which I have more recently met with, together with the assistance I have received from Dr. Finsch's excellent remarks on this genus (P. Z. S. 1870, p. 569), have induced m e slightly to alter m y views, and to propose to arrange the species of Myiozetetes in the following way :- a. Superciliis albis. (1. erythropterus. 2. rufipennis. 3. cayennensis. b'. prim, extus rufescente intus fulvo limbatis 4. similis. c'. prim, extus viridi intus fulvo limbatis 5. texensis. (6. granadensis. 7. luteiventris. 8. sulphureus. At the same time I must say that I am by no means satisfied as to the validity of all the species of section a, as in some cases, as I shall presently show, they certainly run into one another. 1.
