Four specimens were found in the later collections that seem to 

 belong to this species. They are all fragments, and only one, No. 500.104, 

 merits special remark. This is upwards of half of the base of a small 

 trunk with well-marked characters, which are those of this species. The 

 base is perfect, and this was wanting in the type specimens. Both here 

 and on the fractures the internal structure is clearly shown. The armor 

 and woody zones are more clearly brought out than in the types and agree 

 with the description in every particular. The trunk was 10 cm. in diam- 

 eter and the specimen is 8 cm. high. It weighs 0.37 kg. 



No. 500.192 is possibly the terminal bud of a trunk of this species. It 

 shows the scars of the small leaves definitely and concentrically surround- 

 ing the apex of the axis, which is 7 mm. in diameter and not raised above 

 the scars. The bud is somewhat elliptical in cross section, with a diameter 

 of 4 cm. by 6 cm. The specimen is 5 cm. long in the direction of the axis 

 of the bud, but none of the appendicular organs extend as far as the inner 

 fracture, which lies in the woody zone of the trunk. The specimen weighs 

 0.13 kg., or, more exactly, 127 grammes. The other two specimens are 

 very small fragments, doubtfully referred to this species. 



Cycadella contracta Ward. 



PI. LVI. 



1900. Cycadella contracta Ward: Proc. Wash. Acad. Sci., Vol. I, p. 277; Twentieth 

 Ann. Rep. U. S. Geol. Surv., 1898-99, Pt. II, p. 409, pi. cxlviii-cHii. 



The later collections considerably extend our knowledge of this 

 species, although this is done chiefly by three specimens, and notably by 

 one. No. 100.222, which is found to be an extension of No. 500.79, and 

 matches what I called the upper side of the latter specimen, viz, the side 

 opposite that shown on pi. cliii, and top of fig. 1 of pi. cli. The projection 

 shown on the right of pi. cliii proves to be part of the base, which is entirely 

 completed by the much thicker segment constituting No. 100.222. This 

 overthrows my theory that Nos. 500.79 and 500.56 are parts of the same 

 trunk. The latter shows a complete base, and now we have the complete 

 base of another trunk, which was much larger and very anomalous in shape.
