Ridgivay — New Genera of Tiiranmdfe , PipridcT, Cotingidse. 209 



Tyrannopsis ^en. nov. {Tyrannidse.) 



Similar to Tijrittniiis Ciivier, but tip of outermost primaries not attenuate 

 tail relatively sliorter (shorter than (lintanoe from bend of wing to end of 

 secondaries), and nostril much nearer to commissure than to cul men, over- 

 hung by a very broad membrane. Differing from Mijiozda Bonaparte (to 

 which commonly referred) in relatively much larger and stouter bill, shorter 

 and more rounded wing, shorter tail, and shorter tarsus (the latter shorter 

 than middle toe, with claw). 



Type, Muscicapn sulphuren Spix ^ Tyrannopsis sulphureus. 



{Tyrannus + 6\//is, appearance.) 



Tolmarchus gen. nov. {Tyrannidse.) 

 Similar in general structure to Pllangvs Swainson, but bill broader and 

 more depressed (its width at posterior end of nostril equal to more than 

 half the distance from nostril to tip of maxilla and one and a half times 

 its depth at same point), longer gonys (very nearly to more than twice as 

 long as mandibular rami), longer tail (much more than four-fifths as long 

 as wing), much longer tenth (outermost) primary (longer than fourth in- 

 stead of equal to or shorter than first), more exposed nostrils, more scant 

 and conspicuously bristly latero-frontal feathers, longer rictal bristles, and 

 very different style of coloration (under parts grayish white, instead of 

 bright yellow, no white superciliary stripe, etc.). 

 Type, Pitangus taylori Sclater. 



(TbXfxa, bold, daring ; dpx<5s, a ruler, a chief, or leader.) 

 Species: Tolmarchus hahninensh (Bryant), Tolmarchus caudifasclalus 

 (D'Orbigny), Tolmarchus jamaicensis (Chapman), TolmarcJius caymanensis 

 (NicoU), Tolmarchus gahbi (Lawrence), Tolmarchus taylori (Sclatei'). 

 Phseotriccus gen. nov. (Tyrannidse.) 



Apparently nearest to Knipolegus Boie, but differing conspicuously (from 

 all other genera of Tyrannidfe also) in the form of the wing, which has the 

 primaries and distal secondaries much abbreviated, the former all very 

 narrow, the five outermost bent or subfalcate; seventh primary longest, 

 the tenth (outermost) shorter than first. 



Type, Cnipolegus hudsoyri Sclater = Fhxotriccus Imdsoni. 



(<i>at6s, dusky; rpiKKos, a small bird.) 



Allocotopterus gen. nov. {Pipridx.) 

 Most like Machseropterus Bonaparte, but shafts of secondaries excessively 

 thickened, twisted, and expanded terminally into club-shaped or claw-like 

 form ; outermost })rimaries normally broad throughout; tail less than one- 

 third as long as wing, emarginate; nostril small, very broadly operculate, 

 the membrane occupying much the greater part of nasal fossae ; under parts 

 not striped. 



Type, Pijira deliciosa. Sclater = Allocotopterus deliciosus. 

 {'A\\6kotos, unusual ; wnpov, wing.) 



Stictornis gen. nov. ( Cotingidse.) 



Most like Euchlornis DeFilippi (= Pipreolo Sclater, nee Swainson?), but 

 bill much larger, stronger, and deeper, with culmen more strongly arched
