WALCOTT (Charles D.)— Continued 



The author does not consider Climactichnites as tlie trail of a trilobite. 



He describes Prolichniles septemnolatiis Owen and P. Logananus Marsh. 



The author remarlcs tliat many of the impressions made by Proticliiiites tracics were 

 trifid, and made by a i.-rustacean having legs terminating in a joint that had three 

 strong, narrow terminal spines. 



On plate 45, the author illustrates Neolenus serrattts from Burgess Pass, in which 

 figure 4 shows the trifid arrangement of the short, strong spines of the terminal joint 

 of the' cephalic legs. /
