[in consultation with J.T. Dutro, Jr.] This report is in response to your letter of April 18, 1967, in which you indicated that two suites of specimens were critical to your current work:

1) 66ATr82.3, -.4, -.5 and -.6, include no corals. Tom Dutro indicates that 82.3 and 82.6 are certainly Silurian on the basis of the brachiopods. A report will follow.

2) 66ATr109, 109.3, 109.5, 110.2 and 111, are dominantly corals and are covered in the following report. Most specimens are rather poorly preserved and one collection lacks recognizable megafossils. The other four collections probably fit into the range of time represented by Middle and early Late Devonian although only 109.5 is reasonable definite. The other three collections include Amphipora? and my age statement is based entirely on this form, only questionably identified in each case.

Material on which the age statements are based is being retained for our reference collection. The indeterminate material and cuttings will be discarded unless you indicate that we should return it.
