In 1859 Hall described the proximal portion of a multiramous form 

 from the Normanskill shale at Kenwood near Albany, which later on was 

 referred to Clematograptus by Hopkinson. The species was based on a 

 single specimen and no other seems to have been found here since. Lap- 

 worth cites it with a query in the Annals and Magazine from the Arenig 

 but the species has not been mentioned again in the Monograph of British 

 Graptolitcs. Since he also lists it among the Canadian species, we hope 

 that our knowledge of this interesting form will be materially increased in 

 his forthcoming work on the Canadian Graptolites. 



We have been unsuccessful in obtaining the type specimen. Professor 

 Whitfield has kindly informed us that it was originally found by Prof. 

 George Washington Taylor and given to Hall after publication. It is now 

 neither in the New York State collection nor the American Museum of 

 Natural History and Professor Whitfield presumes that it has lately gone 

 to the Museum of Chicago University with Hall's last collection. This 

 collection, according to information from Professor Weller, is at present 

 inaccessible. 



We are then restricted in our conception of the species to the brief 



original description and figure [see pi. 15] which are here copied : 



Body consisting of numerous bifurcating branches, which are arranged 

 bilaterally on either side of a short strong central bar. The branches bifur- 

 cate irregularly and the subdivisions on one side amount to 21, and on the 

 other to 22, while the specimen is far from being entire. The branches are 

 serrated on one side , serratures somewhat closely arranged.
