242 MR. D. G. ELLIOT ON NEW BIRDS. [Apr. 28, 
4. Descriptions of some new Genera and Species of Birds 
belonging to the Families Formicariidz, Pachycephalide, 
and Sylviide. By D. G. Exxioz, F.L.S., F.Z.8., &e. 
(Plates XIX., XX.) 
CLYTORHYNCHUS PACHYCEPHALOIDES, sp. et gen. nov. (Plate 
XIX.) 
Clytorhynchus yenus novum Pachycephalinarum ; rostrum com- 
pressum, subdescendens, ad apicem incurvum ; gonys recurvus, 
fortiter ascendens; remiges secundus, tertius et quartus fere 
a@quales et longissimt. 
3d. Ex toto brunneus; subtus pallidior vie rufescenti-viridis : 
rectricibus apice albis ; rostro et pedibus plumbeis. 
Hab. New Caledonia. 
Upper parts dark rufous-brown, slightly brighter upon the fore 
part of head andrump. Primaries brownish black ; secondaries and 
tertials like the back, with the edges of the outer webs reddish. 
Four central feathers of the tail blackish brown for their entire length, 
the remainder lighter brown, with the ends white, most extensive on 
the first and second, where it includes both webs, and is about half 
an inch in length, becoming much less on the third, and is repre- 
sented on the fourth only by a round spot on the tip of the inner 
web. Underparts light rufous-brown, slightly darker on the flanks. 
Bill strong; upper mandible slightly hooked, lower with a decided 
upward curve, lead-colour at base; the cutting-edges of both mandi- 
bles and point horn-colour. Feet lead-colour, claws horn-colour. 
Total length 63 inches; wing 33, tail 3, tarsus 3, bill at gape 2. 
This curious species, which represents an entirely new genus of 
the family Pachycephalide, holds the same relative position to this 
family as the Yanga sxenopirostris of La Fresnaye (Xenopirostris 
la fresnayus, Bon.) does to that of the Laniide. It is a native of 
New Caledonia ; and the unique specimen from which my description 
was taken is now contained in the collection of the Museum of Natural 
History of New York. 
CLYTOCTANTES ALIXII, sp. et gen. nov. (Plate XX.) 
Clytoctantes genus novum Thamnophilinarum ; rostrum magnum, 
compressum, subrecurvatum ; culmen rectum, apex non incur- 
vus; gonys recurvus, fortiter ascendens; remiges quartus, 
quintus, sextus et septimus fere aquales et longissimi; pedes 
graciles, ungues longiores quam in genere Neoctautes. 
3. Capite et gula nigris, dorso abdomineque plumbeis; alis 
Suscescentibus ; cauda brunneo-nigra ; macula magna intersca- 
pulart alba; rostro nigro, mandibula inferiore ad basin albi- 
cante ; pedibus nigris. 
gd juv. Niger, rufo-brunneo tinctus; capite saturatius rufo ;
