N... 1411. BIRDS FROM MOUNT KILIMANJARO— OBERHOLHER. 911 



wing" pointed, second primary about equal to the .seventh; four prima- 

 ries sinuate on outer webs; outermost primary much (more than 5 mm.) 

 longer than primary coverts. 



The species that appear to belong- to this genus are as follows: 



Oicldomy'ut carulescens cnndrsceiix (Ilartlaiib). 

 Cichlomyia cserulescenn cinerascens (Sharpe). 

 Cichlomyid, toruensin (Hartert). 

 OicJdomyia luf/en>< ( Hartlaiib) . 

 Cichlomyia nio<h'i^t<i (Hartlaub). 

 Cichlomyia minitna (Heuglin). 



6. Dioptrornis. 



Dioptromis Fischer and Reichenow, Journ. f. Ornith., 1884, i>. f)'i (type, Diop- 

 trornis fischeri Reichenow) . 



Bill somewhat compressed, rather vireonine, the culmen more or less 

 curved throughout most of its length, the tip strongly unguhite; rictal 

 l)ristles strongl}^ developed; exposed culmen shorter than middle toe 

 without claw; tail long, about four-tifths the length of the wing; wing- 

 rounded, the second primary shorter than the ninth; four primaries 

 sinuate on their outer webs; outermost primary more than .5 mm. longer 

 than primary coverts. 



This genus appears to be more closel}^ allied to CicJdomyla than to 

 any of the others al)ove diagnosed, but is readily distinguishable from 

 that group. The following species are current: 



Diopiroriiis brunnetis Cabanis. 

 Dioptrornis Jischeri Rei chenow. 

 Dioptrornis nyikmsis (Shelley). 

 Dioptrornis chocolalinus (Ri'ippell). 

 Dioptrornis reichenoivi (Neumaini). 



The following key to the six g-enera of Muscicapida^ above involved 

 may be of some assistance in identitication as well as in further com- 

 parison of characters: 



A. Three primaries sinuate on outer webs; second primary longer than sixth. 

 a. Tail longer — about three-fourths of wing; bill broader; tirst i)ri- 



mary exceeding i)rimary coverts by at least 5 mm Arizelomyia 



a\ Tail shorter — about two-thirds of wing; bill more narrow; first pri- 

 mary exceeding primary coverts by less than 5 mm. 

 h. Bill not shorter tlian middle toe without claw; rictal bristles well 



developed; second primary longer than tifth Muscicapa 



y. Bill shorter than middle toe without claw; rictal bristles weak; 



second primary shorter than fifth Fin-dala 



B. Four primaries sinuate on outer webs; second primary shorter than sixth. 



(I. Bill broad and flat Useonax 



a'. Bill narrow and arched. 



b. Rictal bristles reaching beyond middle of bill; second primary 



shorter than ninth; bill shorter than middle toe without vhiw .. Dioptrornis 

 b\ Rictal bristles not reaching to middle of bill; second primary 



longer than eighth; bill about equal to middle toe without claw. . Cicldornyia 



CICHLOMYIA CiERULESCENS (Hartlaub).
