TWENTIETH REPORT ON THE STATE CABINET.

Graptolithus multipasciatus. 



The separated and broken stipes referred by me to Graptolithus Sagit- 

 tarius* of HisiNGER are probably of the same species, occurring as they 

 do in great numbers in the same beds in which this one was found. 



In other species with a similar general arrangement of parts, the main 



stipes are frequently bifurcated ; the bifurcations beginning near the base, 



and continuing as far as the parts can be traced in the stone (fig. 8). In 



some of the species of this character the cellules begin near the base of 



the stipes, while in one species they are not known to exist except on the 



outer branchlets.
