with Descriptions of New Species. 275 



killed in the flock, I do not know whether the rest wefe the same or 

 not. Bill ashy brown with small black spots at the extremity. Leno-th 

 0-447 ; extent 0-725 ; end of tail 0*020 from the end of wing. 



" I suppose it does not belong to South America, for in that case it 

 should rather be found here in summer."

Dr. Gundlacli writes me, 



"This is the specimen found by Lemb 35^6 in the market at Havana, 

 and mentioned in his work as marinus. I have now my doubts whether 

 it is this species or not, but it does not seem to be argentatus, for it is 

 larger. Though it is not in good condition, I have kept it to discover 

 its real name. It being besides a young bird, its true plumage cannot 

 be known. I expect you to be able by the size and form of its bill to 

 know it." 



Bemark^.—^Thx?, example agrees very closely with a si^eci- 

 men in my collection of the young of argentatus of middle 

 age. 



My specimen of the young of marinus is largei-, and stouter 

 in form; the back mottled with much darker feathers, and the 

 bill larger and stronger.
