[The single specimen collected by Mr. Belding cannot by any means 

 be referred to the so-called var. lucasanus, the tail being- marked not 

 only by a very distinct subtermiual narrow black baud, but with more 

 or less distinct narrow bars entirely to the base. The imder plumage 

 is very light colored, the usual abdominal belt of dusky markings being 

 indicated only by very small hastate streaks ; the tibise are creamy 

 white, barred with light rufous, aud the sides more distiuctly barred 

 with dark brown aud rufous. It is somewhat doubtful wbether the 

 principal character assigned to " lucasanus^^ (the uniform rufous tail with- 

 out subtermiual black bar; will XJrove constant, even in birds from the 

 cape. — E. R.]
