ANNOTATED LIST OF THE TYPES OF INVERTEBRATE CRETACEOUS FOSSILS 



IN THE COLLECTION OF THE ACADEMY OF NATURAL 



SCIENCES, PHILADELPHIA. 



BY CHARLES W. JOHNSON. 



The following list of types and figured specimens was made during 

 1902. Leaving Philadelphia early the following year, I have been 

 unable until the present time to verify some of the notes on syn- 

 onymy, etc. No attempt has been made to fully work out the syn- 

 onymy, so that only the published synonyms bearing on the types are 

 given, usually where recent generic changes have been adopted. The 

 generic position of many of the species is doubtful, as they are based 

 on casts often lacking essential characters; the grouping of some of 

 the species in families is therefore only provisional. Although a very 

 thorough study was made of all the cretaceous material, a few types 

 which should be in the collection are missing. I have not recorded 

 these, as they may be found upon further search.
