Prof. Neumann exhibited and described examples of the 

 following new subspecies of Capitonidae : — 



Lybius bidentatus iKTHiops, subsp. n. 



Adult male and female. Similar to L. b. aquatorialis, 

 Shelley, from Uganda, Kavirondo, Unyoro, Niam-Niam, &c., 

 but somewhat smaller and with a much smaller bill. 



L. b. (Ethiops. Culmen 26-29 mm. ; wing 96-108. 



L. b. aquatorialis. Culmen 29-34 mm.; wing 101-111. 



Hab. Shoa, South Ethiopian Lakes, and Omo Region. 



Type in the Tring Museum : S • Uba, Omo Region, 

 25.i.01. O. Neumann coll. 



Obs. Examples of L. b. atquatorialis from Niam-Niam are 

 slightly smaller than those from Lakes Victoria and Albert. 



Lybius undatus senafenses, subsp. n. 



Adult male and female. Similar to L. u. thiogaster, Neum. 

 from Massaua and the Bogos Country, but the crown is 

 glossy black, without white stripes ; the feathers of the throat 

 have the black middles broader and the white margins 

 narrower, while the back is darker. There is an indication 

 of white eyebrows and black cheeks, though these markings 

 are not so sharply defined as in Mr. Keuleman's figure of 

 Pogonorhynchus undatus in Marshall's ' Monograph of the 

 Capitonidae,^ plate 13, where this form is badly depicted. In 

 L. u. thiogaster the entire sides of the head are striped with 

 black and white. 



Hab. Region south of the Bogos Country (Upper Mareb 

 River, North Tigre). 



Type in the Tring Museum : ^ . Senaf e Pass, 28. xii. 02. 

 G. Schrader coll. Other specimens from Arba, Schiko, 

 Ghadi Saleti, and Ali Beret are in the Tring Museum; and 

 from Senafe, Adigrat, and Rayrayguddi in the British 

 Museum. 



Obs. In the countries south of Tigre to Lake Tsana and to 

 the west of Lake Tsana another form occurs, L. u. squamatus, 

 Heugl. {cf. J. f. O. 1863, p. 15). In this the white edges of 

 the feathers of the throat are wanting, and the breast and 

 belly have not the distinct bars of L. u. undatus.
