and otliors not ; some have the center decayed and some seem to consist 

 more of bracts than essential organs: hut I think that (Hfference of age 

 would account for all these differences. Some ai-e probably (piite young 

 antl innnature, othei-s fully I'ipe, and still others old and ready to decay. 

 (Locality: PI. LXXX, Xo. 91.) 



PI. LXX.XllI, I'ig. 1, the central figure of the group shown in the 

 photograph scut by Mi'. Tyson to Mr. F. B. Meek, of which an account 

 was given in tlie historical part of this paper (p. 414), is another and 

 quite different view of the Johns Hopkins University Cycad Xo. 1. It 

 is nearly in the same position as that of Professor Fontaine's pi. clxxix, 

 but the trunk was inclined toward the camera so as to sliow the summit. 

 The ferruginous band is seen running the whole length of the trimk on 

 the left. 



PL LXXXIII, Fig. 2, on the left of the figure last consideicd, is a 

 view of the Johns Hopkins University Cycad X'^o. 3, described by Professor 

 Fontaine on p. 192 of his monograph as "Fragment Xo. 2," but not 

 figured by him. It is not shown here to the best advantage and will be 

 mentioned again in the description of the next plate. 



PI. LXXXIII, Fig. 4, is a view of the base of the Link tnmk (W. C, 

 B., Xo. 1481.) 



PI. LXXXIV, Fig. 1, is a side vk.w of the Johns Hopkins University 

 cycad Xo. 5, described by Professor Fontaine as "Fragment Xo. 2." 

 At the time I descrilxnl the specimens, in January, 1895, it was not 

 with the other specimens and I did not treat it. It was discovered soon 

 after in the basement and I was notified of the fact. On May 11 of 

 that year I described it and had the photograph made which constitutes 

 PI. LXXXIV, of which it occupies the center (Fig. I), the fragments 

 X^os. 2 and 4, not previously figured, occupying the left and right (Figs. 

 2 and 3), respectively. The specimen seems to consist of a little over half 

 of a trunk of medium size of conical shape and elliptical cross section. 

 It is truncated at the summit and oblique at the base. As stated by 

 Professor Fontaine on p. 191 of his monograph, it has a circle of cemented 

 ferruginous sand similar to that of Xo. 1, which, like that, is wholly super- 

 ficial. In this case, however, the plane at which the formation of this 

 ferruginous cement took place was much below (or possibly above) the 

 center of the trunk.
