Rio Negro, ex Bi rli p ch Both specimens are now in tin- M. < /. 

 The Brat of these we identity as the bird generally known ai Lopho- 

 triccvi Bpiotferus (Lafresnaye), and 1 1 1 * - second tin- bird named Mota- 

 cilla galeatus Boddaerl (Tabl. PI. enl., 1783, p. 24 ( ayenne, ei

The original labels, however, reveal the fad that tin- second speci- 

 men only is the type of Lafresnaye's Todirostrum rpiciferum. The 

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

 spicifer, T. porte e*pi nob.," and refers to the original publication. 

 The description agrees perfectly with the specimen, which proves to 

 be Colopteryx galeatus (Bodd.). Hellmayr (Abh. K. Haver, akad. 

 WlSS., L912, 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 Lophotriccus 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 Todirostrum 

 spiciferum Lafresnaye sinks into the synonymy of Colopteryx galeatus 

 (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. squamicristahis (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 galcahis (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
