order as then called) ; there is no sign of infrabasals, and in a slender dorsal cup 

 like that there is no possible room for interradials between the radials. Yet in 

 the diagram there are five infrabasals, large basals, and three orders of radials 

 including the axillary. The description combines the facts of the figure with 

 the errors of the diagram in a singular way, indicating a strange confusion of 

 ideas. Slightly condensed it reads as follows: The "Basaha" (number not 

 stated) form a low funnel, to which circumstance the calyx owes its elongate 

 form (showing that he means the first row of erect plates seen in the figure, 

 and not any invisible plates below, or above, them) ; the lower part of the six- 

 sided "Parabasalia" project "knopformig" (answering precisely the description 

 of the (first) radials in the figure) ; upon these, wedged into their reentering 

 angles, follow five rays, each of which consists of "drei Radialia," the upper of 

 these axillary (whereas the figure shows beyond a doubt that the lowest of the 

 three radials whose upper plate is the axillary, is the " knopfformig " plate, 

 resting upon the reentering angles of the "Basalia" which form the "Trichter," 

 and that there is no room for any "Parabasalia" at all) ; the Interradials, which 

 rest upon the horizontally truncate edge of the "Parabasalia," shov.^ a larger 

 Interradial of the first order, etc. (the only possible horizontally truncate plates 

 in the second range are the radials and the anal plate, which the author must 

 have been thinking of when he wrote this). 



I have good specimens of an undescribed elongate form substantially the same 

 as Schultze's species, from the Devonian of Colle, Spain, — a perfectly plain 

 Batocrinoid. 



INADUNATA.

Hitherto no representative of the assemblage of peculiar dicyclic Eifelian 

 genera grouped under this family has been reported in this country, except the 

 species described by Hall under Myrtillocrinus americanus. It is now known, 

 however, that there are at least two other genera in our approximately equivalent 

 Middle Devonian that must be referred to it. 



The genus Arachnocrinus was founded by Meek and Worthen (Geol. Surv. 

 Illinois, II, 177) upon a species which had been described by Hall as Cyathocrinus 

 bulbosus (15th Rept. N. Y. St. Cab., 1860, 123) from the Onondaga (= Upper 

 Helderberg = Corniferous) of western New York; this was done chiefly upon
