CERTHIACEyE. 83 



Lamprornis (usually written incorrectly Lamprotornis), Turdus, Pliyllornis, Accentor, Grallina, 

 Henicitrus, Sylvia, Pants, and Regvliis ; or 



b. Eighteen rcmiyes, the first being deficient, in 



Anthus, Motacilla (Plate III, figs. 1 and 2), and Hylophilus TEMM. (Sylv. pwcilotis TEMM., 

 PI. Col. 173, 2 ; S. amaiirocephala LICHT.), Sylvia chrysoptera, WILS., Turdus aurocapillus, WILS., 

 and others. 



2. Short rounded icings, of which the Jirst four, five, or six remigcs are graduated, and 

 the following primaries are nearly of the same length as the secondaries and 

 tertials. In this case the first primary seems never to be deficient. Here the 

 genera 



Troglodytes, Pterojrfoc/tus, Menura (Platelll, figs. 11 and 12), Pitta, Myophonus, Myiothera, 

 Cinclus (distinguished as remarkably in the structure of the wings by the agreement in length of 

 the second and third remiges with the two following, these four being the longest, as by the dense 

 downy clothing Avhich covers, not only all the spaces, but also the intervals between the con- 

 tour-feathers, and even the oil-gland), Ixus (T. ochrocephlus LATH., T. atricapillits TEMM., 

 T. leucocephalns Mus. FRANK.), Copsyclnts WAGL. (T. macrurus LATH., T. mindanensis), 

 Cindosoma, Timalia, Pomatorhinus, Maliirus (marginalis} Synal/axis (setarid), Opetiorhynchus 

 (turdineus NEU WIED, Turd, scolopaceus LICHT., to which I refer Campylorhynchus scolopacem 

 SPIX, Picolaptes zonatus LESS., and Pic. brimnicapillits GUR., Mag. v, i, 47, and also Opet. 

 rufus Mus. FRANK. \Turdus figulus LICHT.], Op. rupestris KITTL., of which the wings arc rather 

 more acute, and Ochelorliynchus ruficaudus METEN. The first three species, of which I have 

 examined the skins, have the dilatation of the pectoral tract strongly divergent at the extremity, a 

 structure intermediate between the ordinary one and that of Menura and Grallina. Anabates 

 also, in my opinion, is best placed here, and forms the transition to the Certhiaceaa, which the 

 preceding genera likewise approach very closely. 



9. CERTHIACE.E. 



This group, although inferior to the preceding in extent, is, nevertheless, much more variable 

 pterylographically. In respect of the form of the saddle, it presents the two sections already 

 repeatedly mentioned. 



A. With a single saddle in the spinal tract. 



1 . Sitla. Saddle rhombic, elongated, almost lanceolate ; dilatation of the pectoral tract 

 perceptibly separated at the end. Nineteen remiges, ten on the hand, the first very short, the 

 third, fourth, and fifth the longest. Tarsus behind, with simple, undivided lamina?. S. europaa, 

 carolinensis, canadensis.
