PART II. 



The chief purpose of this list of the type specimens of the fos- 

 sils collected and described from the palaeozoic rocks of Wiscon- 

 sin is to make available to the local collector and student of such 

 objects the information that will enable them to know by what 

 specialist they were described, the formation from which they 

 were collected, the publication in which the original description 

 of the species was first made, the locality from which they were 

 collected, and the present place of deposit of the type specimens. 



In the early days of the science of Paleontology in the State 

 of Wisconsin, many descriptions of new species of fossils were 

 made without figures and in several instances only a general ref- 

 erence as to the locality was given. As the specimens in many 

 cases were derived from the local collector by the specialists who 

 have made the descriptions, some errors of locality are known to 

 have occurred, and observations have been introduced where 

 apparently needed to correct such errors. In many instances 

 species have been described under several generic and specific 

 terms ; these synonyms have, we believe, all beer worked out so 

 as to enable the student to correctly identify the species. 



Our first reference is to that publication in which the original 

 description of the species will be found ; should there have been 

 no figure of the specimens to accompany the description, we have 

 as a second reference, referred to that publication in which will 

 be found a redescription of the species with a figure. This may 

 be by the original described of the species or by another authority 

 using the first specific term, a corrected reference or a synonym, 

 as the case may be. In many instances, since the publication 

 referred to in the first or second reference may be one that is not 

 accessible to the student, we have referred as a third reference to
