No. 8.— NEW FOSSILS FROM THE VICINITY OF 
BOSTON. 
BY THOMAS H. CLARK. 
Since the publication of Crosby's Geology of the Boston Basin, 
which contains a chapter on palaeontology by Grabau, very little 
has been written on fossils from the immediate vicinity of Boston. 
Sears (1905) has added to the localities at which Lower Cambrian 
and Pleistocene fossils have been found; Shimer (1907, 1907a) 
has published two short papers dealing with Cambrian species; 
more recently, Raymond (1913, 1914) has added two trilobites 
to the meager fauna; and Shimer^ has brought up to date our 
knowledge of Post-glacial fossils from Boston Bay. 
One reason for the paucity of publications upon the palaeontol- 
ogy of the region is the fact that seldom is an investigator fortu- 
nate enough to stumble upon anything "worth while." There 
must be a great many single fossils, which would be of interest 
to local scientists, tucked away in museum drawers because their 
finders have not considered them sufficiently important to de- 
scribe. With this in mind, the writer feels no need to apologize 
for the short notices which follow, but rather hopes that they will 
serve to bring out more of like nature. We shall never know one 
half of what is our due if we wait for a mythical someone else who 
is "going to monograph the whole fauna." 
1. LOWER CAMBRIAN FOSSILS FROM REVERE BEACH. 
Recently, while looking over the pebbles on Revere Beach, I 
noticed one particularly because of its resemblance to the red 
Cambrian limestone at Attleboro. When I broke it open, I was 
delighted to find within it the pygidiuni of a minute Lower Cam- 
brian trilobitc. I proceeded to search for similar ones, and found 
some fifty or sixty pel)blcs and cobbles of red limestone and shale, 
mostly two or three inches in diameter. Some of these were 
identical, lithologically, with the Lower Cambrian limestone at
