38 ANNUAL REPORT OF THE 



REPORT ON INVERTEBRATE PALEONTOLOGY. 



By Alpiieus Hyatt. 



The revision of the genera of fossil Cephalopods has been con- 

 tinued during the past official year and completed through the 

 Triassic period, the fossils rearranged and placed in better shape 

 as regards labelling, especially those of the Senary and other 

 Palaeozoic collections. 



Representative species of all the genera have been selected, 

 mounted, and are now in large part ready for exhibition in the 

 Stratigraphic Collection. 



The Department is indebted to Dr. R. T. Jackson for a large 

 amount of work done in selecting materials for exhibition in the 

 Stratigraphic Collection, and in superintending the work of mount- 

 ing and labelling them. 



He has also spent considerable time upon the Brachiopoda, 

 rearranging parts and greatly improving the condition of the 

 collection as a whole. 



Part of the time of two Assistants has been available, and this 

 has been spent in mounting and labelling fossils for exhibition, 

 as described above. 



Mr. Charles Schuchert reports progress on the Palaeozoic Star- 

 fishes which he borrowed for study.
