am able to call attention to the discovery of the remains of a large 
Pecilopod in the Utica slate, north of that village. The remains 
consist of a large endognathary arm of seven or nine joints, 
provided with long backward curving sabre-like spines, an 
portion of a thoracic somite, probably one-half of the ventral sur- 
face of the anterior somite. For this species I propose the name 
Eurypterus ? Clevelandi, n. sp., and will give a detailed escrip- 
tion with figures of the specimens, in a future number of the 
Journal. Cc. D. WALCOTT.

Th Ss pam mphle et is a collection of sivet apers on the Delaware 
Valley paleolithic implements, severally by Messrs. ne C. ABBOTT, 
the discoverer of them, H. W. Ha G. F. Wrieat, Lucie 
Carr and M. E. Wapsworts, with concluding sone by F. W. 
Putnam. Mr. Putnam closes his remarks respecting these very 
interesting discoveries and his own visit to the segmeee.s as follows: 
Dr. Abbott has stated, in his historical summary of the 
n 
lithic implements from the gravel at various depths and at differ- 
ent points. The relation of the circumstances under which one 
of these was found will be sufficient to convince you that the 
implement was in the position hows it was buried by the four 
feet of gravel which had been deposited over it.
