Rio Negro, ex Berlepsch). Both specimens are now in the M. C. Z. 

 The first of these we identify as the bird generally known as Lopho- 

 triccvs sjnciferns (Lafresnaxe), and the second the bird named Mota- 

 cilla galeatvs Boddaert (Tabl. PI. enl., 1783, p. 24 — Cayenne, ex 

 Daubenton's PI. enl. 391, fig. 1). 



The original labels, however, reveal the fact that the second speci- 

 men only is the type of Lafresnaye's Todirosirum spicifenwi. The 

 label of this specimen, in Lafresnaye's handwriting, reads, "Tod. 

 spicifer, T. porte epi nob.," and refers to the original publication. 

 The description agrees perfectly with the specimen, which proves to 

 be Coloptery.v cialcahis (Bodd.). HellmaNT (Abh. K. Bayer, akad. 

 wiss., 1912, 26, abh. 2, p. 22, footnote) was the first to notice the dis- 

 crepancy between the diagnosis of T. spiciferum and the Upper 

 Amazonian bird to which the name Lophotriccvs spiciferus has been 

 applied by authors, and with his customary keenness suspected its 

 identity. Compared with fresh specimens from Surinam (Penard 

 collection), Lafresnaye's type is very similar, except that the bill is 

 now of a horn color, and the coloration, in general, has a rather faded 

 and slightly more brownish appearance, which, of course, is readily 

 accounted for by the age of the specimen. Thus the name Todirostnim 

 spiciferum Lafresnaye sinks into the synonymy of Colopteryx galeahis 

 (Boddaert). 



By this unfortunate disposition of T. spiciferum, the genera Colop- 

 teryx and Lophotriccus are both seriously affected. Lophotriccus 

 was proposed, without designation of type, by Berlepsch (Proc. Zool. 

 soc. London, 1883 [= 1884] p. 553), who listed as representative 

 species L. spicifer (Lafr.) and L. squamicristaius (Lafr.). The geno- 

 type was subsequently designated by Sclater (Cat. birds Brit, mus., 

 1888, 14, p. 86), who selected Lophotriccus spicifer Lafresnaye. Lopho- 

 triccus is thus a synonym of Colopterus Cabanis. The latter being 

 preoccupied, Ridgway (Proc. U. S. N. M., 1888, 10, p. 519) has sub- 

 stituted Colopteryx, by which name the genus has been known ever 

 since. But Colopteryx is antedated by Lophotriccus and must be 

 replaced by it. The only species in the genus should thus be called 

 Lophotriccus galeatus (Boddaert). 



The genus erroneously known as Lophotriccus is now without a 

 name, since Orchilus Cabanis, which would otherwise be applicable 

 here, is preoccupied by Orchilus Morris (Cf. Oberholser, Proc. Biol, 

 soc. Wash., 1918, 31, p. 203), and since Orcheilus Gray is merely an 

 emendation. We therefore propose for this genus
