the area. The edges of all the plates are beveled so as to permit the 

 imbricated arrangement without producing a very rough outer surface. 

 There are two ambulacral pores in the central part of each piece, 

 arranged transverseh'. 



Inter ambulacral areas. — The interambulacral areas are covered b}' 

 live rows of plates, which imbricate upward and outward. This ar- 

 rangement allows the plates in the middle row to project their under 

 beveled edges upon the plates on each side, while the plates in the 

 outer rows project their beveled edges upon the inter- ambulacral plates. 



Ovarian plates. — One Ovarian plate shows two genital pores, and 

 another one shows three, and one apparently shows four, but the de- 

 pressed condition of the specimen will not permit of too much certainty 

 respecting these pores. The ocular pieces, or pieces between the 

 Ovarian plates, are a little smaller than the Ovarians, and one of them 

 shows two pores, or at least what appears under an ordinar}- magni- 

 fier to represent two pores. 



The apical disc is composed of several plates, but the condition of 

 our specimen will not permit us to determine with certainty their 

 exact arrangement. 



Locality. — This species is described from a single specimen in the 

 collection of Prof. A. G. Wetherby, who discovered it iu rocks of the 

 age of the Kaskaskia Group, in Pulaski County, Kentucky. 



CATALOGUE OF THE FLOWERING PLANTS, FERNS 

 AND FUNGI GEO WING IN THE VICIN- 

 ITY OF CINCINNATI. 



By Joseph F. James. 



The following catalogue has been compiled from personal observa- 

 tion, and from the catalogues of Messrs. Lea and Clark. Their lists 

 contain the names of some species which I have not identified as found 

 in this locality. In such cases their respective names are given in 

 brackets. I am especially indebted to Mr. T. W. Spurlock for valu- 

 able information and specimens, which, but for his indefatigable work 

 in collecting, I should perhaps not have seen. Thanks are also due to 

 my brother, Mr. Davis L. James, to Dr. J. H. Hunt, Dr. R. M. Byrnes, 

 Mr. F. W. Langdon, Mr. C. G. Lloyd, Mr. J. L, Taylor and others, for 

 specimens and information.
