pillus, I propose to change the name of this species to Lanio 

 lawrencii. 



4. Tachyphonus napensis. 



Tachyphonus napensis, Lawrence, Ann. Lye. N. Y. viii. 

 p. 42. 



I have carefully compared Mr. Lawrence's type of this 

 species (which is apparently an Indian skin from the Rio 

 Napo) with the series of T. surinamus in my collection and 

 that of Messrs. Salvin and Godman. As Mr. Salvin and I 

 have already pointed out (P. Z. S. 1867, p. 571), the Upper 

 Amazonian form of this bird is slightly different from the 

 typical form of Cayenne, but I can only regard it as a sub- 

 species, which may be called Tachyphotms surinmnus napensis. 



5. Tachyphonus nattereri. (Plate VL fig. 1.) 

 Tanagra cristatella, Natt. MS. 

 Tachyphonus nattereri, Pelz. Orn. Bras. p. 214. 



Niger ; crista pilei medii exsurgente aurantiaca ; dorso postico 

 fulvescente ; alarum tectricibus superioribus minoribus 

 et subalaribus necnon remigibus ad basin albis. Long, 

 tota 5"4, alae 2"7, caudse 2"4. Fern. Rufescens; subtiis 

 et in remigum marginibus dilutior. 

 Hab. Villa Maria, Mato Grosso {Natt.) . 

 Obs. Sim. T. delattrii, sed alarum tectricibus albis et uro- 

 pygio fulvescente diversus. 



This is an excellent species, approaching T. delattrii in 

 form, but easily distinguishable, as above mentioned. I am 

 greatly indebted to Herr v. Pelzeln for sending me the typical 

 specimens from Vienna for examination. 



6. Nesospingus speculiferus.
