flanks Front's l)rown, toward abdomen barred indistinctly with 

 blackish ; under tail coverts Prout 's brown ; lesser under wing- coverts 

 deep mouse gray; greater under wing coverts mikado brown; edge 

 of wing mixed mikado brown and mouse gray. Bill dull black, washed 

 obscurely with brownish at base of mandible ; tarsus and toes verona 

 brown (from dried skin). 



Measurements. — (In millimeters) : Male (one specimen, type), 

 wing 73.2, tail 64.0, exposed culmen 14.9, tarsus 38.4. 



Female (one specimen), wing 69.0, tail 57.5, exposed culmen 14.5, 

 tarsus 37.6. 



Two specimens with sex not indicated, wing 66.6-72.2, tail 56.6- 

 67.2, exposed culmen 14.7-15.5, tarsus 37.0-39.3. 



Range. — Straits of Magellan, Chile (known from four specimens 

 from Port Otway). 



Remarks. — The present form is based on four skins, two of which 

 bear date of February 10, 1888, secured by naturalists of the. "Alba- 

 tross" at Port Otway, in the Straits of Magellan. Though the date 

 on two of these specimens is not indicated it is certain that all four 

 were collected at the same time. Kittlitz deHcrihed Pteroptochos 

 ruhecula from a male obtained at Concepcion, Chile. In making com- 

 parisons in the present connection I have considered a series of four 

 skins from Valdivia as representative of the typical form. 



Tsenioptera pyrope ignea subsp. nov. 



Characters. — Similar to Tamioptera pyrope pyrope (Kittlitz [1831, 

 p. 191]), described from Tome, Concepcion, Chile, but decidedly
