36 ANNUAL REPORT OF THE 



KEPORT ON THE DEPARTMENT OF VERTEBRATE 

 PALAEONTOLOGY. 



By Charles R. Eastman. 



Departmental work has been conducted during the year along 

 essentially the same lines as indicated in the last Report, chief 

 attention having been directed to a systematic review of the De- 

 vonic fishes of the Ohioan and Dakotan provinces. Several of 

 the older collections belonging to this Museum, notably those 

 brought together by Mr. Orestes H. St. John and Prof. Samuel 

 Calvin from the Mesodevonian and Neodevonian of Iowa, yielded 

 very interesting results. Valuable aid was also derived from a 

 quantity of material obtained a number of years ago by the late 

 Prof. O. C. Marsh, for the loan of which the Museum is indebted 

 to the courtesy of Prof. Charles Schuchert. 



Incidental to the selection of fossil fish material at Yale Uni- 

 versity, copies of two unpublished lithographic plates, signed by 

 Sonrel, were discovered, and were recognized as having been 

 designed to illustrate Dr. C. T. Jackson's descriptions of Car- 

 boniferous fishes from the Albert Coal Mine of New Brunswick. 

 The plates were still in the hands of the engraver at the time 

 Jackson's Report was published, in 1851, and appear never to 

 have been distributed. By means of these two copies, or, it may 

 be, proofs, it became possible to identify a number of the original 

 types and figured specimens in the collection of this Museum and 

 in that of the Boston Society of Natural History. A re-investiga- 

 tion of Jackson's material and other remains from the same locality 

 has since been undertaken. A report on the fish-fauna from the 

 Waverly of central Kentucky is nearly ready for publication. 



Following is a list of the accessions and publications during the 

 current year.
