In another note three new subspecies are described — 

 Mirafra africanoides harei, Damaraland, Phyllastrephus 

 terrestris rhodesia, N.W. Rhodesia, and Andropadus im- 

 portunus noomei, NE. Transvaal ; while the description of 

 Spinas symonsi, previously printed on a separate unpaged 

 slip, is reprinted with additional matter. 



A final note is of great interest and deals with the para- 

 sitic liabit of some Soutli-Af rif;an Weavers and Finches. 



It appears to us that a new word is required to denote the 

 liabit now known to be j)revalent in several groups of birds 

 of laying their eggs in the nests of other species. Perhaps 

 Coccygisni would meet the case. At any rate, Mr. Roberts 

 seems to have proved without doubt that the Pin-taded 

 Widow-bird ( Vidua serena) and Rendairs Seed-eater (^Ana- 

 molos/jiza imherdis) should be included in this category, and 

 in the latter case he is actually able to give a photograph of 

 the young Seed-eater being fed by a pair of Black-chested 

 Warblers {Prinia fluvicans) who acted as foster-parents; bis 

 observations on this matter are full of interest. 



The second paper quoted contains a description of Chloro- 

 petella suahelica, gen. et sp. no v., for a little Flycatcher 

 nearest to Chloropeta, but differing in its narrower and more 

 (jecurved bill and longer and more numerous rictal bristles. 

 The type, and apparently the only specimen^ was obtained 

 by Mr. Roberts himself at Myiai^ an outpost some forty 

 miles south-west of Dar-es-Salaam^ on the coast of what 

 was (Jerman East Africa. 



In the same note Numida 2J(ip'^ll^sa damarensis from 

 Windhuk, S.W. African Protectorate^ and Guttera edouardi 

 symonsi, Karkloof^ alt. 3j500 ft., Natal, are described as new 

 subspecies. 



Shufeldt on a fossil bird from Colorado. 



[Fossil Remains of what appears to be a Passerine Eird from the 

 Florissant shales of Colorado. By R. W. Shufeldt. Proc. U.S. Nat.

The fossil which Dr. Shufeldt here describes consists of
