basal collar, the nasal saddle and pair of subnasal strips; the mandibular shoe and basal strip; 

 three large symmetrical pieces and two pairs of small lateral pieces, in all seven. (Thus as in 

 F. arctica, lacking only the pair of prenasal strips ; thus exactly as supposed to be the case in 

 F. cornictdata. The loss of the pieces of the upper mandible makes the same difference in the 

 bill as occurs in F. arctica ; but the moult of the mandibular shoe effects less change in the 

 appearance of the bill).
