rUOM EQUATOETAL AFEICA. 421 



as Gordon's lieutenant at Sobat, A. considerable amount of 

 interest, therefore, attaches to the meeting of these old friends in 

 the midst of the desert of Korusko. 



On looking over the present collection, we are at once struck 

 by the presence of so many species hitherto believed to be 

 peculiar to "West Africa ; but it will be noticed that these species 

 are from the Nyam-nyam district and from Semmio's country, 

 while those from the Gazelle River are many of them well-known 

 inhabitants of North-eastern Africa and Senegambia. It is evi- 

 dent that Mr. Bohndorif, when he crossed the watershed and 

 descended into the Nyam-nyam country, passed the boundary 

 line of two faunas, and that the animals of the Nyam-nyam country 

 are those of the Gaboon and the Congo rather than those of the 

 Lado district or of Kordofan. He informs me that the character 

 of the countries are different; in Semmio and ISdoruma the 

 forests clothe the sides of the rivers as in the countries of 

 Western Africa, while in the Bahr el Ghazal the sides of the 

 rivers are covered with grassy country, with occasional clumps 

 of forest. 



I have followed in the present paper the classification adopted 

 by Dr. Hartlaub in his memoirs on Emin Bey's collections from 

 Equatorial Africa, as it is in connexion with the recent explo- 

 rations of the latter traveller that Mr. Bohndorff's collections 

 possess the greatest amount of interest. I subjoin a list of the 

 localities whence the specimens are recorded. 



In the Nyam-nyam country, Sassa, Semmio, and Ndoruma are 

 marked on the map above referred to. Mangbanga, an ajfUuent 

 of the Welle Eiver, is not put down in any map at present. 



Dembakir (26° W. long.) is on the slope of the watershed 

 between the Gazelle-Eiver Province and the Nyam-nyam country. 

 Jur or Djur, Gattas, and Muschra-rec, the port of the Gazelle 

 Eiver, are marked in several maps. 



Dem Suleiman, or Dem Zebehr, is the Moudirieh or capital 

 of the provinces of Bahr el Ghazal and Nyam-nyam. It 

 is the residence of Lupton Bey, and is called by the negroes 

 " Juku." 



In the following paper I have referred principally to the great 

 work by Von Heuglin, the ' Ornithologie Nord-ost Afrikas,' and 

 also to the two papers by Dr. Hartlaub : —
