220 CRATEROPODIDyE. 



extending down the Malay peninsula. This bird does not appear 

 to be found above 4000 or 5000 feet of elevation. In Burma it- 

 is as common at the level of the sea as on the hills. 



Habits, <$fc. This species is found in thick forests in companies 

 of ten or more, searching the leaves for insects. 



Subfamily LIOTRICHIN^E. 



The Liotrichince comprise those members of the Crateropodidce 

 which are strictly arboreal, and in which the sexes are differently 

 coloured. The first character separates them from the Braeliy- 

 pteri/f/ince, and the second from all the other subfamilies. 



The genera Aetliorliynchus and JEgitliina have two moults a year, 

 and thus show affinities with the Sylviidce. The other genera have 

 only the usual autumn moult. 



The genera Cephalopyrus and Hypocolius are migratory to some 

 extent. The other genera are sedentary. 



All the Liotrichince, so far as is known, lay spotted eggs. Minla 

 and Myzornis may prove to be exceptions to this general rule, but 

 the evidence regarding these two genera is incomplete and unsatis- 

 factory so far as it goes. 



Key to the Genera. 



a. First primary about half the length of 



second. 



'. Tail considerably shorter than wing. 

 a'. The secondaries falling short of tip of 

 wing by a distance not greater than 

 half the length of tarsus. 



a"'. Tail-feathers curved outwards . . LIOTHBIX, p. 221. 

 b'". Tail-feathers straight. 



a 4 . Upper tail-coverts falling short 

 of tip of tail by less than the 



length of hind toe CUTIA, p. 222. 



b k . Upper tail-coverts falling short 

 of tip of tail by about the length 

 of tarsus. 

 a 5 . Tarsus much longer than 



middle toe with claw. 

 a 6 . Bill stout, strongly notched 



and hooked at tip. 

 a\ Bill about half the length 

 of head; culnien well 



curved PTEKUTHIUS, p. 223. 



b 7 . Bill as lono- as the head ; 



culmen nearly straight . AETHORHYNCHUS, p. 228. 

 b 6 . Bill slender and very little 



deflected at tip. 

 c 7 . Width of bill behind the 

 nostrils equal to half the 

 length of bill from that 

 point to tip ^EGITHINA, p. 220.
