Mr. P. L. Sclater on new species of Tyrannidae. 423 



abdomine et crisso citrino indutis, pectore et lateribus nigro 

 flammulatis : subalaribus citrino -flams : rostro corneo 3 mandi- 

 bulcB inferioris basi alba ; pedibus nigris. 



Long, tota 8*5, alse 4'5, caudse 37, rostri a rictu 1-2, tarsi 074. 



Hab. In litt. reipublicse Nov. Granadse in vicinitate urbis S. 

 Marthse. 



This fine Myiodynastes is a close ally of M . audax and M. lutei- 

 ventris, but is readily distinguishable by its stronger bill, longer tail, 

 which is slightly forked, and the lighter surface of the body below ; 

 this is nearly pure white on the throat and middle of the belly, 

 being rather sparingly flammulated on the breast and sides, which 

 latter parts, along with the crissum, are tinged with yellow. 



The example of this bird in my own collection was obtained from 

 MM. Verreaux of Paris, and was received from their collector at 

 Santa Martha. 



The true type of the genus Myiodynastes, Bp. (a generic term 

 published by the Prince, like many others, without characters, or 

 even the indication of any exact type), was intended, I believe, to 

 have been the Tyrannus audax, Auct. The name first appeared in 

 print in the ' Comptes Rendus' for April 3, 1854, in connexion 

 with M. luteiventris ; but it also occurs in the catalogue of birds 

 collected in Cayenne by M. Desplanches* (p. 11), where it is ap- 

 plied to T. audax. The division seems a natural one, connecting 

 Pitangus and Tyrannus. 



CONTOPUS MESOLEUCUS. 



Obscure cineraceus, olivaceo mx tinctus, pileo, alis et cauda nigri- 

 cantibus, secundariis dorso proximis albo extus marginatis : 

 subtus obscure cineraceus, vitta longitudinali a mento corpus 

 descendente cum venire toto albo, flamcante tincto, hypochon- 

 driis et crisso cineraceo adumbratis : fasciculo plumarum utrin- 

 que ad later a uropygii, alis obtecto, albo : rostro nigro, mandi- 

 bulce inferioris basiflamda : pedibus nigris. 

 Long, tota 675, alae 4'0, caudse 27. 



Hab. In Mexico meridionali, et in rep. Guatemala (Skinner). 

 This bird is easily recognizable by the creamy-white medial line, 

 which passes from the chin to the cvissum, expanding greatly on the 

 belly. My examples are from Orizaba, collected by Botteri. Mr. 

 Gould possesses a specimen from Guatemala of the same species. 

 The form is quite typical, the wings being very long, and the second 

 primary, which is the longest, considerably (by 0*15 inch) exceed- 

 ing the first and third, which are equal. The curious white tufts 

 at the side of the uropygium, covered by the wings, are very notice- 

 able in this species more so than in my examples of C. borealis. 



* This little tract is extracted, I believe, from the Memoires of a learned Society, 

 published at Caen. The only copy I have ever seen was given to me by the 

 author himself in 1857, shortly before his death. In it is established a new genus 

 of Tyrannidce Planchesia for Muscicapa fuliginosa, Gm. (PI. Enl. 5 74. fig. 1) ; 

 and the generic term Syrichtha, the type of which appears to have been unknown 

 to Mr. Gray, is used for Tyrannus curtipes, Sw.
