In innjalojjtrrait, nnialus, bruniieicujnllus, and their allies, the scale is more developed, us in tropical Wrens. In C. rapidrulux, rujinurha, huiiuii)i,vlc., the nostril is more like Jtonacolnus and IlfleodijlcH, namely, at the an- terior end of the nasal groove, bordered behind by membrane, and not above. In these the tail ia shorter and less graduated than in the tvpe. C. capitflratuH is placed by Cabunis under Jleleodi/fex, on account of its i)ecnliarities of nostril; it differs, however, in .'shorter (uil, siiorter bill, weaker legs, and the middle toe shorter than thu tarsus, not longer. The followiii!' table exhibits the peculiarities of the species before luo in reference to the nostrila:â A. Nostrils rather linear, liorizontal, in lower side of nasal groove, and over- hung broadly hy uie-'ibraue thickened at edges : C. hrunHeicdpillus, uffiuis, ixilltscens, baltetitus, , zoiuitns, purdus. B. Nostrils more oval, the overhanging men^brane reduced to a ridge on tipper edge of nasal groove: C. vurie</atus, brevirustria, zonutoidtSyjocosuit (nodtriLs more linear), albibrunneua, C. Nostrils as in Ileleodijtes; broadly oval or rounded, in anterior end of nasal groove, with thin membrane behind: C. capiatrutuK, rujinucha, humilis. The transition, however, from one to another form, is vf "y gradual, (inil it is quite diflBcult to say, in regard to some species, whether they belong more properly to one secti«m or to another.
