228 ON NEW SPECIES OF TIMELIINE BIRDS. [Mar. 15, 



birds in the island of St. Thomas. This new species has a brown 

 style of coloration which is characteristic of many Timeliine birds, 

 but it seems to find its nearest ally in a Malayan genus Graleroscelis 

 of Malacca and Borneo. It differs, however, from that genus in 

 certain evident characters, which may be diagnosed as follows : — 



Amaurocichla, gen. nov. 



Similar to Crateroscelis, but distinguished by the shape of the 

 wing, the first primary being nearly as long as the second. Addi- 

 tional characters are : — The bill is as long as the head, and rictal 

 bristles are absent, while the tail-feathers are somewhat acuminate. 

 The type is : — 



Amaurocichla bocagii, sp. nov. (Plate XX. fig. 1.) 



Adult. General colour above uniform chocolate-brown, the 

 wings and tail a little darker than the back ; lores and sides of 

 face dark brown like back, the ear-coverts slightly rufescent, like 

 the sides of the neck ; cheeks and throat whitish, with a slightly 

 indicated malar line of rufous ; lower throat and rest of under 

 surface of the body rufous ; the abdomen isabelline ; under wing- 

 coverts isabelline ; quills sepia-brown below. Total length 5 

 inches, culmen 0'8, wing 2'55, tail 1*.55, tarsus 0-95. 



Ilah. San Miguel, West coast of St. Thomas, West Africa. 



While describing this interesting species I may add the diagnosis 

 of another Timeliine bird recently acquired by the British Museum, 

 which also seems to be undescribed, and for which I propose the 

 following name : — 



TuRDiNUS MOLONEYANUS, sp, nov. (Plate XX. fig. 2.) 



Adult. General colour rufous brown, inclining to chestnut on the 

 lower back, rump, and upper tail-coverts, as well as on the wings : 

 primaries dusky, externally light rufous; tail-feathers light rufous 

 brown, externally shaded with chestnut ; crown of head slightly 

 more dusky than the back ; an indistinct line of ashy grey above 

 the eye, and the feathers below the latter ashy; ear-coverts brown; 

 throat and under surface of body tawny rufous, more rufous on the 

 fore neck, chest, and sides of body, the latter inclining somewhat to 

 reddish brown ; thighs like the abdomen ; under tail-coverts light 

 chestnut ; axillaries and under wing-coverts tawny rufous ; quills 

 dusky below, rufescent along the inner web. Total length G"C inches, 

 culmen 0-85, wing 2"7, tail 2*5, tarsus TO. 



Hab. Gold Coast. 



The typical specimen was presented to the British Museum by 

 Sir Alfred Moloney, who procured it during the time that he was 

 Governor of the Colony.
