Sub-Family REGULINAE. 

 REGULUS.' Cuvier. 



Segulus, CuviKR, Leijons d'Anat. Comp. 1799 — 1800, (Agassiz.) (Type Motacilla regulus, Linn., Regulaa cristalus, 

 Koch.) 



Ch. — Bill slender, much shorter than the head, depressed at base, but becoming rapidly compressed ; moderately notched 

 at tip. Culmen straight to near the tip, then gently curved. Commissure straight ; gonys convex. Rictus well provided with 

 bristles ; nostril covered by a single bristly feather directed forwards. Tarsi elongated, exceeding considerably the middle toe, 

 and without scutellae. Laieral toes about equal ; hind toe with the claw longer llian the middle one, and about half the toe. 

 Claws all much curved. First primary about one-third as long as the longest ; second equal to fifth or six. Tail shorter than 

 the wings, moderately forked, the feathers acuminate. Colors olive green above, whitish beneath. Size very small. 



I am unable to appreciate any such difference between the conmon North American Reguli 

 as to warrant Cabanis in establishing the genus Phyllobas ileus for the calendula. The bristly 

 feather over the nostril is perhaps less compact and close, but it exists in a rudimentary 

 condition. 



Crown in adult plain olivaceous, with a concealed patch of crimson calendula. 



Forehead and line over the eye white, bordered inside by black, and within this again is 



yellow, embracing a central patch in the crown of orange satrapa. 



Forehead and line through the eye black, bordered inside by whitish, and within this 

 again by black, embracing an orange patch in the centre of the crown cuvieri.
