line to three lines. It is probable that, when perfect, they are at a 

 uniform distance of about half a line, and that when they are more 

 remote some of the intermediate ones have not been preserved. The 

 substance of the stipes is rough, black and shining, and apparently with 

 some irregular longitudinal striae. 



]So cells or serrations can be seen in any of the specimens exam- 

 ined. There are five or six longitudinal stipes in the width of two lines. 

 In the specimen above, fig. 2a, however, they arc more distant, and this 

 may represent a distinct species.

Ptilodictya tarda. (N. sp.) 



Description. — This species is founded on a single specimen, about nine 

 lines in length and two in width. At the basal extremity, for a length of 

 two lines, the cells do not appear to be arranged in regular rows. At two 

 lines from the base a bifurcation takes place at an angle of about 85^. 

 Above this the cells are arranged in eight or nine longitudinal rows with 

 a fine, thread-like, angular ridge between each two rows. At the length 

 of about six lines another bifurcation takes place, the rows of cells being 

 continued on both branches. The cells are nearly circular, each surrounded 

 by an obscurely elevated margin. They are, on an average, one-twelfth 

 of a line in diameter, and about their own width distant from each other. 

 Between each two cells there is a small depressed space about the size of 

 the cell itself. 



The specimen is firmly imbedded in the rock, so that all its characters 

 cannot be made out. It has, however, the compressed branching form, 

 characteristic of the genus. The edges of the stem cannot be distinctly 

 seen, but they appear to be acutely rounded. The thickness of the stem 

 seems to be nearly one line.
