The locality here called Lansdowne is the same as Schoolhouse Hill, 

 in which the Link trunk occurs (see p. 431), previously referred to as 

 near Arbutus. In fact it is about midway between Lansdowne, on 

 the Baltimore and Ohio Railroad, and Arbutus, on the Baltimore and 

 Potomac Railroad. The formation is supposed to be Arundel. Here 

 Mr. Bibbins collected for the Woman's College of Baltimore a cone of 

 ^4. angusticarpus Font. This is a dissected cone of poor preservation, 

 showing the axis of most of the cone and the bases of a number of scales 

 fairly well. It occurs in a hard ferruginous sandstone. PI. CXIV, Fig. 

 10, gives this cone. The shape and size are well shown in this specimen. 

 It bears the number W. C. B., 6324.

All the plants treated in this paper from the Federal Hill region, 

 and probably all that had been previously described, were taken from 

 clay pits and street excavations at the foot of Federal Hill in Baltimore, 

 south of the basin and east of the park in which Federal Hill is located. 

 The localities are all on or near Covington, Clement, and Jackson (for- 

 merly Belt) streets. The collections, mentioned in their chronological 

 order, are as follows:
