Catalogue of type specimens. In my report for last year refer- 

 ence was made to the cataloguing of the type and figured specimens^ 

 of fossils contained in the museum collections. No such cata- 

 logue has been in existence, and the fossils which have been used 

 for purposes of illustration throughout the history of the paleon- 

 tology of Xew York have been scattered through the collections 

 both in the State hall and in Geological hall, some of them bear- 

 ing distinctive marks indicating the use which they had served, 

 but many without any such indication whatever. This w^ork 

 was begun in the summer of 1S99, and has been regarded as one 

 of the most important parts of our museum industry. It has now 

 been brought toward completion, lists having been compiled 

 for the following groups of fossils, the number set opposite each 

 name indicating the types and illustrated specimens: sponger 

 147; crinoidea 63^; brachlopoda 1100; lamellibranchiata 1020; 

 pteropoda 49; gasteropoda 2G0; cephalopoda 400; vermes 95. 



iThis number indicates only the specimens from the Hamilton gronp which 

 were the basis of the descriptions published by Prof. Hall in the 15th annual 

 report of the state cabinet. There are a few additional types of the criuoids 

 which are to be added to this enumeration.
