than were formerly possible. It is found e.g. that both graptolites 

 of the Clinton shale, Monograptus clintonensis and 

 Retiolites venosus are identical with two graptolites ( M . 

 priodon and R. geinitzianus) that have a very wide 

 distribution in Europe and characterize one of the many graptolite 

 horizons of the European Upper Siluric. Thereby it becomes pos- 

 sible to correlate with precision the upper Clinton beds of New 

 York with a definite European graptolite horizon. 



Genera of the Paleozoic corals. On several occasions refer- 

 ence has been made to the study of the Paleozoic corals which was 

 carried on during the later years of the life of Prof. James Hall 

 and provisionally brought to a close not long after his death. The 

 undertaking was one of broad scope and attended with many diffi- 

 culties. So serious did the latter appear that it was deemed wise 

 not to attempt the publication of the work in the form in which its 

 author left it, but to insure its accuracy by placing it for revision 

 in the hands of an expert student of the corals. My desire to bring 

 about this revision has not been successful until this year when an 

 arrangement was perfected with Dr T. Wayland Vaughan through 

 which his services will be given to the work as he can command 

 them. Dr Vaughan has been able to devote some time to this under- 

 taking during the past season and will continue his efforts to un- 

 ravel a very tangled and involved problem which has already cost 

 a large expenditure of time and effort. 



Devonic crinoids of New York. Sufficient progress has been 

 made in the study of the crinoids to justify the expectation of early 

 completion of the Camerate genera. 



Monograph of the Devonic fishes. This work, referred to in 

 my last report, is now in press. 



Mastodons. In a previous report I entered into a detailed 

 account of the discoveries of remains of mastodons in this State 

 since the original excavation of such remains, a short distance 

 below Albany, in 1705 [Report State Paleontologist 1903]. The 

 following memoranda are here added to the record.

? 1799, 1855. The paragraph which follows is from Dr W. 

 M. Beauchamp's bulletin on Indian Place Names in New York [N. 

 Y. State Mus. Bui. 108. 1907]. 



Chemung has various forms, as that of Skeemonk in 1777, and 

 Shimango in 1779. In 1757 the French spoke of the " Loups of
