brevicauda, (Bodd.) (PI. Enl. 706. fig. 1), which is, however, much 
smaller. It is of a uniform ferruginous brown above and white be- 
low, passing into a cinereous tinge on the sides. Some brown colour 
is mixed with the feathers on the sides of the breast. The bill is 
black, the tarsi plumbeous; the thighs and the under wing-coverts 
brown. 
2. GRALLARIA MODESTA. (PI. XCIV.) 
G. supra intense brunnescenti-olivacea, alis caudaque nigricanti- 
brunneis olivaceo tinctis: subtus olivacea, flavescenti-albido 
Jlammulata ; ventre medio flavescenti-albido: tectricibus sub- 
alaribus pallide castaneis : mandibula superiore plumbea, hujus 
apice et tomiis et mandibula inferiore, nisi basi, albicantibus : 
pedibus pallide brunneis. 
Long. tota 6:2, alee 3°2, caudee 1°8, tarsi 1°75. 
This is a rather uniformly-coloured species, of which the British 
Museum contains a single specimen. There are indications of darker 
marginations to the feathers of the nape and back. The breast fea- 
thers are medially yellowish-white, broadly margined with olivaceous. 
3. CHAM£ZA MOLLIssIMA. (Pl. XCV.) 
C. supra brunneo-castanea, remigibus rectricibusque intus nigri- 
cantibus : capitis lateribus et corpore toto subtus nigris, albo 
dense transvittatis: uropygii plumis laxis, elongatis, densis- 
simis : rostro Chameezee marginate simili sed minore. 
Long. tota 5°75, alee 3:2, caudee 2°5. 
This peculiar Ant-thrush, of which there is one specimen in the 
British Museum, has the lower back very densely feathered, the 
coverts reaching to within an inch of the end of the rectrices. The 
wings are shorter than is usual in Chameza—the 4th, 5th, 6th and 
7th primaries being nearly equal in length, but the 5th rather the 
longest ; the tail rather more lengthened ; the formation of the feet 
is much the same. 
Above the colouring is of a brown chestnut, rather darker towards 
the tail ; the sides of the head and whole under-plumage are blackish 
barred with white, every feather having three or more transverse 
white bars. A slight tinge of castaneous is intermixed, particularly 
on the breast. 
4. Formicivora caLuinota. (Pl. XCVI.) 
F. olivacea ; pileo summo et nucha nigris : loris, capitis lateribus, 
et corpore subtus ad imum pectus cinereis : abdomine pallide 
flavicanti-viridi : tergo lete castaneo, pennis quibusdam nigris 
supra marginato: alis nigris, carpo et tectricum marginibus 
Jlavis : secondariis et rectricibus olivaceo marginatis : rostro 
subulato, mandibula superiore nigricante, inferiore pallide 
plumbea : pedibus plumbeis. 
Long. tota 4°0, alee 2:0, caudze 1°7. 
This is an exceedingly pretty species of Formicivora, distinguished 
No. CCXC.—ProcrepinGs oF THE ZOOLOGICAL SOCIETY.
