for the most part, systematic. He described a great number of new 

 species, genera and families. His insight into relationships of animal 

 forms was rapid, and his apprehension of generic references usually ac- 

 curate. The determination of genera from partial, fragmentary remains 

 and internal casts, especially as shown in his work on the Cretaceous and 

 Tertiary formations of Xew Jersey, was remarkable. Among contrilm- 

 tions to science which merit the distinction of being classed as discov- 

 eries were his detection of the muscular impressions in "true Lingula'' in 

 the Trenton Limestone, his observations on the internal appendages of 

 Atrypa, his reference of the fossil forms Dictyophyton and Uphanta'nia 

 to sponges, his description of a fossil scorpion from the Silurian rocks of 

 America (afterwards made by Scudder the type of the family Eoscor- 

 pionida), his notice of new forms of marine algge in the Trenton Lime- 

 stone and description of the occurrence of a Balanus from the Marcellus 

 Shale. The long series of papers on systematic paleontology, in which 

 many new genera and species, observations in morphology and correla- 

 tion, are given, have firmly identified Professor Whitfield's name with 

 American paleontolog}-. 



Unostentatious, of a reserved, almost severe demeanor, animated Ijy an 

 intense love of his science, his life was passed peacefully and pleasantly, 

 jamid unruffled domestic relations, in unbroken association with the ob- 

 jects of his conscientious and unremitting study. 



Professor Whitfield was married at L'tica. X. Y., in his twentieth 

 year. His wife died in Xew York in 1887. Four children were born 

 of this marriage, of whom one, a son, died in youth, and three, two sons 

 and a daughter, survive.
