198 ZOOLOGICAL RESEARCHES 



The species , collected by us in Liberia , have now reached 

 the number of 238. 



1. Asturinula monogrammica (Temm.). — Robertsport. 



2. Syrniwn nuchale , Sharpe. — Young female in down , 

 obtained Dec. 4*^^* at Robertsport. (The nestling of about the 

 same age I collected at Monrovia is dated April 22"'^). 



3. Scoiornis longicauda (Drap.). — Robertsport. 



4. Hii'undo rustica , L, — Several specimens were collected, 

 the first of which is dated Oct. 12'\ the last Nov. 18*\ 



Having now before me the considerable series of 12 

 well-sexed and dated Liberian specimens , which are col- 

 lected in the most different periods of their stay in that 

 country , I will shortly describe the different stages of 

 plumage from their arrival in autumn up to their depart- 

 ure for Europe in spriug. 



a. Female, shot at Robertsport, 12 October 1889. 

 Upper surface strongly glossed with steel-blue, quills and 

 tail-feathers faintly glossed with green and looking rather 

 worn and faded. The outermost pair of tail-feathers are 

 not developed to full length. A very narrow frontlet and 

 the whole chin and throat are pale rufous , the cross-band 

 on the chest is grayish olive-brown , the rest of the lower 

 surface white, the feathers on the breast intermixed with 

 some rusty ones, certainly indicating the beginning of 

 moulting , under wing-coverts white with a slight vinaceous 

 tinge; white spots on tail-feathers very small. Wing 11 

 cM., longest tail-feathers 6,2 cM. The specimen makes the 

 impression of being a bird of the year. 



h. An unlabelled specimen, shot at Roberts- 

 port, at what date I cannot say, but any how before Oct. 

 20*^'' 1889, as the whole consignment has been shipped for 

 Holland on that day. In size and coloration of the upper 

 surface , throat and pectoral band this specimen resembles 

 N°. a , the lower surface , however , including the under 

 wing- and tail-coverts, is uniformly tinged with vinaceous. 

 Like in the preceding specimen the white spots on the tail-
