imich worn and whitened and shows many large, sohd fruits, similar to 

 W. ("., B.. Xo. 1484. It is 29 cm. high and 28 cm. in maximum diameter. 

 The rock is lighter and more porous than most of the specimens of this 

 species. (Locality: PL LXXX, No. 45.) 



PI. LXXX\TI, Fig. II, 9, shows one of the narrower sides of the Gray 

 trunk, W. C, B., Xo. 6354, fully illustrated on PI. CIV. 



PI. LXXXVII, Fig. -II, 10, is a good group view of the Smith trunk, 

 W. C, B., Xo. 1482, and shows the terminal bud clearly. This is a much 

 worn and laterally compressed trunk, but apparently almost complete. It 

 is exceedingly oblique at the base, and presents the appearance of having 

 leaned 40° to 45° from the perpendicular. There is a Avell-defined conical 

 bud at the apex, which, however, looks as if it grew from one side, but 

 standing the trunk on its oblique base renders this bud vertical, as it 

 doubtless was when growing. It is set in a slight depression and sur- 

 rounded by much worn scars of leaves and bracts. The material of this 

 specimen is a light-colored sandstone, quite soft, but except where worn 

 off it is covered with a black pigment, probably due to vegetable growth. 

 The height in the direction of the axis and terminal bud is 17 cm., but the 

 broad face on the side of which the bud stands is 25 cm. from base to highest 

 point. This face is 28 cm. wide. The maximum thickness is 12 cm., 

 but at some points this is reduced to 9 cm. It has a girth of 67 cm.

PI. LXXXVII, Fig. II, 11, shows the outer surface of the Smith 

 fragment, W. C, B., No. 1483. 



This is a very irregular fragment from the side of a trunk that was 

 probably of large size. The position it occupied on the trunk can not \)e 

 ascertained, but it may have been near the base. It includes a consider- 

 able portion of the axis, one of the main fractures being a vertical radial 

 one, and the other at right angles to it also radial, but very oblique to the 

 axis, running out to the surface on one side. The third fracture is trans- 

 verse, and the whole fragment has a sort of triquetrous shape, the outer 

 surface forming the broader side and having the rounded form of the 

 trunk. Over most of the surface the upper' parts of the leaf scars have 

 l)een .systematically, and as it seems artificially, broken off to a depth of 

 2 cm. or 3 cm., usually to near the bottom of the depressions. The por- 

 tions left, however, afford a fairly correct idea of the whole. The rock is
