No certainty can be attached to the suggested zonation until more localities are uncovered within the Monkton along its entire exposure and the fossils described. However, it can serve as a useful frame of reference to be modified as new evidence comes in.

NOTES AND OBSERVATIONS Occurrence of the Ring-necked Duck in Newfoundland. — The Ring-necked Duck (Aythya collaris) appears to be a common breeding summer resident of Gander, New- foundland, and this north-easterly extension of its range is worthy of record. My first observation of this species at Gander on May 8, 1948, coincided with the first breaking up of the ponds in this area. These ponds were not entirely free of ice until two weeks later. Two pairs raised broods in Caledonia Pond, scarcely three hundred yards from my resi- dence, and concentrations of unattached males, as many as seventeen, were observed there during early July. A visit on June 19 to another small pond and a series of gullies within two miles of this specific area re- vealed a total of five females and six males. The first brood of nine downies appeared in Caledonia Pond on July 31, and on the fol- lowing day an additional female brought out a brood of eight. A downy was collected on August 1, and is now in the Newfound- land collection of the National Museum, wher
