white shaft-line^^ ^and both the latter moreover with a 

 broader , rufous shaft-streak. The outer webs of the pri- 

 maries are much paler than those of the secondaries, the 

 primary coverts and bases of secondaries pure black al- 

 though both series of wing-coverts, with the exception of 

 the outermost feather of the greater ones , the outer web 

 of which is pale sandy brown , like those of the primaries. 

 Most of the greater wing-coverts are tipped with pure 

 white, like in the adult stage, whilst the resting ones and 

 all the median wing-coverts are broadly tipped with very 

 pale rufous. 



Chin, breast, abdomen and under tail-coverts ochra- 

 ceous , both latter intermixed with pure white feathers , 

 centre of breast , whole chest and a narrow moustachial 

 streak russet brown, each feather with paler centre; a few 

 feathers on the centre of the chest with dark brown cen- 

 tres, the two outermost tail-feathers very faintly tipped 

 with white. Iris dark brown, bill brown, basal half of 

 lower mandible whitish, feet flesh-color. 



Wing 12 cM., tarsus 3,2, bill 1,8. 



53. Xenocichla syndactyla (Sw.) *). 



Butt. N. L. M. 1885, p. 179; id. 1886, p. 255. 



Several specimens from Schiefifelinsville and Hill Town. 

 The males in all our specimens are larger than the fema- 

 les, and the bill about 3 mM. longer and more compressed. 



1) Dr. Hartlaub, the Author of the generic name Xenocichla, has not given 

 any diagnosis of the genus, but as he separates X. syndactyla , which is to be 

 considered the type of the genus, from Trichophorus on account of its straight, 

 compressed bill, these latter characters must be made the chief characters of 

 the genus. Hartlaub describes the bill of X. syndactyla z.% recti usculo, com- 

 presso, while the type of the genus Tnchophorus , T. barbatus, has the bill 

 bent downwards, broad at the base and only towards the point somewhat com- 

 pressed. (Conf. Temm. PL Col. Vol. IIT. pi. 88, and Heine, J. f. O. I860,, 

 p. 138). With regard hereupon I consider Crhiiger eximius of Authors to be a 

 Xenocichla, and Xenocichla simplex as well as lencopleura and indicator of Mr. 

 Sharpe (Cat. Birds Br. Mus.) to be true members of the genus Criniger.
