the points of which latter diminish, and become weak, according to 
the species so gradually, that it is impossible to fix a limit between 
this subgenus and the Thrushes.(1) 
There are other Shrikes, whose superior mandible is straight, and 
only hooked at the tip. Their form passes by insensible gradations 
to that of the Fauvets and other Motacillz.(2) 
(1) The species with the strongest beaks are, for instance: the Cape-Shrike, 
(Lan. collaris, Gm.); Enl. 477, 1; Vaill. Afric. pl. Ixi, Ixii—The Boubou, Vaill. 
68 (Lan. boulboul, Sh.)—The Brubru, Vaill. 71 (Lan. capensis, Sh.).—La Petile 
Pie-gr. de Madag. (Lan. madagascariensis, Gm.) Enl. 299.—La Petite Pie-gr. 
bleue (Lan. bicolor, Gm.); Enl. 298.—La Pie-gr. dela Louisiane, (Lan. americanus, ) 
Enl. 397.—The Sourciroux, Vaill. 76, 2, or the Tangara verderoux of Buff. ( Tana- 
gra guianensis, Gm.).—The Black-Headed Shrike of the Sandwich Islands, (Lan. 
melanocephalus, Gm.) Lath. Syn. I, 165.—La Pie-gr. a queue pointue, (Lan. pyrr- 
honotos,) Vieill. Gal. 135 
The genus Lanro of Vieill. is founded on an arcuate-beaked Shrike; the edges 
of whose upper mandible are somewhat angular. It is the Tangara mordoré of 
Buff. Enl. 809, 2 (Lan. atricapilla, Gm.). 
Among those species most nearly allied to the Thrushes, we may admit the Mus- 
cicapa tamnophiloides, Spix, 26, 1.—L’Oliva of Vaill. 75 and 76,1 (Lan. oliva- 
ceus, Sh.) —The Gonolec, (Lan. barbarus, Gm.); Enl. 56, Vaill. 169.—The Lan. 
gutturalis, Daud. Ann. Mus. ILI, 144, pl. xv; or the Pie-gr. Perrin. Vaill. 286.— 
Le Merle @ plastron noir (T'urdus zeilonus, Gm.); Enl. or the Bachakiri, Vaill. 67 
(Lan. bachaleiri, Sh.).—La Cravatte blanche, Vaill. 115 (Motac. dubia, Sh.).—The 
Turdus crassirostris, Gm.; Lath. Syn. IU, 34, which is the same as the Tunagra 
capensis, Sparm. Carls. pl. xlv, and several others quite as equivocal. It is from 
this subdivision, with weak bills, that Vieill. has established his genus wees | 
Galer. 143. 
His Vireo only differs from it in the beak being a little shorter and more slender, 
Vir. flavifrons, Vieill. Am. 54, or Muscic. sylvicola, Wils., I, vii, 3.—V. musicus, 
Vieill. 52, or Music cantatrix, Wils. I, xviii, 6, or Music. noveboracensis, Gm.— 
V. olivaceus, Ch. Bonap., or Museic. oliv. Wils. Ul, xii, 3, or tamnophilus agilis, 
Spix, 34, 1.—V.gilvus, Ch. Bonap., or Muse. melodia, Wils. V, xlii, 2. vi lead 
us almost directly to the true Fauvets. 
(2) Le Blanchot, Vaill. Afr. 285, (Lan. icterus, Cuv.) or Thamnophilus, Vieill. Ga- 
ler 139.—The Grand battara, Azz. or Thamnophilus magnus, Pr. Max. or Th. albi- 
venter, Spix, 32. —The tchagra, Vaill. 70; (Lan. senegalensis, Spix, Lan. eollurio 
melanocephalus, Gm.) Enl. 479, 1 and 279, 1.—The Fourmillier huppé, Buff. (Tur-. 
dus cirrhatus, Gm.) The Pie-gr. a huppe rousse d’ Amerique, (Lan. canadensis, Gm. ) 
Enl. 479, 2, is the female.—The Tachet, Vaill. 77, (Lan. punctatus, Sh.).—The 
Pie-gr. rayée de Cayenne (Lan. doliatus) Enl. 297, 2, or radiatus, Spix,35, 2.—The 
Pie-gr. bridée, (Lan. virgautus, Tem.) Col. 256, 1.—The Pie-gr: masquée, (Lan. per- 
sonatus, Id. or Lan. nubicus, Licht.) Col. 256, 2—The Thamnophilus lineatus, 
Spix, 33.—Th. strigai Id. 36, 2.—TZh. melanoceph. 1d. 39, 1—Th. leuconotos, 
Ib. 2, , 4 
The Pie-gr. rousse eo Madag. (Lan. rufus, Gm.) Enl. 298. Oi 
It is also among these straight beaked Shrikes that must be placed the Geni 
longup., Vaill. 42, (Lan. galericulatus, Cuy.), but it leads to the Vanga.
