APPENDIX D. 



CURRENT WORK OF THE MUSEUM FOR 1880. 



(Appendix B of 34th Report.) 



List of Species and Specimens of Cephalopoda from the Scho- 

 harie Grit, Upper Helderberg, Marcel lus Shale, Hamilton, 

 Tully Limestone, Genesee Slate, Portage, Chemung and 

 Waverly Groups; as arranged in the cases of the State Museum. 



Note. — The numbering in the following list corresponds with the 

 specific labels, and indicates the number of specimens from each 

 formation. The letters denote the number and rank of specimens in 

 each species. Eeferences are made to the localities and to the plate 

 and figure of the Palceontology of Neiv York, vol. V, pt. II, when used 

 for illustration. The letters (T), (W), etc., show where the specimens 

 are to be found — whether in the table-cases, wall-cases, etc. Those 

 without such designation are arranged in the drawers under the 

 Clinton and Medina series of rock-specimens. Entries marked as 

 "returned," refer to specimens borrowed from the cases as previously 

 arranged which are now returned. All others are additions to the 

 original collections. 



The specimens here enumerated have been either figured in illustra- 

 tion, or have been used in the study and comparison of species 

 described in vol. V, part II, of the Palceontology of New York.
