Dall) : Similar to the adult, but collar obsolete, greater wing-coverts and secondaries broadly tijiped with pure wldte, and feathers of the sides and llanks uniform brownish gray, without white tips. A very curious specimen from Northern Europe (No. 57107, "hoher Norden;" Schliiter Coll.) is exactly intermediate between this species and li. hrenta, and is probably a hybrid. It has the uni- form colors of the body characteristic of the B. ; but the shade is rather lighter, present- ing a more appreciable demarcation of the black of the jugulum, and has a more bluish castâthe wing-coverts in strong and abrupt contrast with the black secondaries. The white of the neck is in two isolated crescents, as in bemicla. It measures as follows : Wing, inches ; culnien, ; tarsus, ; middle toe, This form is very closely allied to the coninioii l^rant Goose, and takes its place on the Pacific coast, wliero the latter does not seem to occur. The present species is quite rare on tlu^ eastern coast. ]Mr. Hen-. Please note that these images are extracted from scann
