Comment:	The matrix, as indicated, is marble and the rare foram specimens are poorly preserved. The little information I have been able to glean from these suggests a Late Paleozoic rather than post-Paleozoic age. Sticking my neck out perhaps much further than is warranted, I would guess that some of the specimens represent Nankinella sp. of the kind found in rocks of Pennsylvanian age. I have cataloged the material here, but if you would like to have Betty Skipp or someone else look at the material for further ideas, I would be glad to lend it to them. I showed the specimens we were able to locate to Norm Saches and he didn’t think they could be post-Paleozoic either. Congratulations on spotting these in the first place. I would appreciate a copy of the Anchorage map with this and the other locality spotted on it for our locality records.
