Mus. Bergen {Balestrand, Sogn, Norway, Gl^ S" N. Lat, 19th January, 

 1880. By Mr. Sv0edrup.) 



Length of the bill from the tip to the mouth 89"'", to the front of the 

 nostrils 39""", and to the fore border of the eye 113'"'". Length of toes 

 with claws : outer toe 118, middle toe 127, inner toe 9G, and hind toe 

 21'"™. Tarsus 92, wing 550, and tail 166'"™. 



In this specimen, when fresh, the lateral spots on the bill are of a 

 purer yellow color than the preceding, without red ; also the whole 

 culmen is jet black, without the shaded yellow transverse stripe towards 

 the forehead ; the margin of the lower mandible with the lamella quite 

 light flesh-colored. 



On the whole like the former, although without the grayish tinge on 

 the sides of the head. 



Coll. of Norway Scientific Soc. Trondhjem. ( 9 f ad., Stjord- 

 alen, Norway, 63^ 25" N. Lat. — The first half of February, 1880.) 



Length of bill along gape, ST""; from the tip to the front of the 

 nostrils, 39'"™ ; to the fore border of the eye, 116™™. Length of toes 

 with claws : Outer toe 117, middle toe 125, inner toe 95, and hind toe 

 22mm. Tarsus 92, wing 560, and tail 163™™. 



The shortest distance from the openings of the nostrils to the yellow 

 lateral spot on the base of the bill amounts to 18™"" . The lateral spots 

 are in connection with each other over the culmen by a narrow yellow 

 stripe, which forms an angle in the middle of the culmen with the point 

 turned towards the front ; the margin nearest the feathers of the fore- 

 head, blackish. From the upper and hinder border of the skin of the 

 nostrils, but not in immediate connection with the yellow at the base 

 of the bill, a yellowish brown spot almost 8'"'" long extends towards the 

 tip to cr. 10™'^ from the hind border of the openings of the nostrils. Skin 

 of the chin brownish. 



The whole plumage dazzlingly white, with faint yellowish edges on 

 the feathers of the fore part of the head. 



Coll. of ^S'orway Scientific Soc. Trondhjem {Jun. ; Hitren, Nor- 

 way, Q30 30" N. Lat. Last of December, 1879. J5y J/r. Arnet). 



Mr. Storm* gives the total length at ] ,040""™. The distance from the 

 tip of the bill to the mouth I foiind in the stuffed specimen to be 83™™, 

 to the fore border of the nostrils 37™™, and to the anterior angle of the 

 eye 109™™. Length of the toes with claws: Outer toe 114, middle toe 

 120, inner toe 91, and hind toe 18™™. Tarsus 92, wing 500™™, and tail 

 134™™. The slight differences in the dimensions given by Mr. Storm 

 (l. c.) of the same specimen probably arise from some difference in our 

 respective modes of measurement. The dimensions given here are car- 

 ried out in the same manner as all those undertaken and introduced by 

 me into this treatise.
