SOME NEW FOSSILS FROM EASTERN 
MASSACHUSETTS.

terrane, intermediate between the Cambrian and Archaean, ac- 
cording to the generally understood delimitations of those for- 
mations, in eastern Massachtisetts, has been touched upon be- 
fore in the few papers that deal with the geology of this dis- 
trict; but a systematic treatment has not been published in 
which enough detail has been given to make the relations of 
the formations clear. I now propose to give a preliminary 
paper on a region of about sixty square iniles, situated on 
the western rim of the Boston basin and extending west and 
northwest from the city of Waltham for ten miles across a 
region usually left uncolored on geological maps. To the 
east, we have the well known Boston Basin series, consisting 
of the Roxbury conglomerate and the Cambridge slate, with 
various intrusives, and flanked to the eastward bv the three
