A STROLL BY THE SEA-SIDE. 
BY EDWARD S. MORSE. 
















Tue sea-side naturalist has certain advantages not 
sessed by his inland confrére, in the greater variety of Ale, 
and in the profusion of material which is daily exposel 
to him by the tides, and in the debris strewn in windrows 
along the shores by the heavy storms that sweep along the 
coast. While he may turn inland and in an hours wi 
reach the representatives of animals which are found thro 
out the continent, the inland naturalist must visit the 
side to see the living representatives of certain classes 
are almost, or quite exclusively, marine. 
Even a whole branch of animals, the Radiates, com 
such animals as the sea-anemones, jelly-fishes, stars 
and sea-urchins, has only one feeble microscopic rep i 
tive in fresh water. The class of bivalve. mollusca, with 
unique sea forms of razor-clam, mussel, scallop, and r 
dreds of others, is represented in our fresh-water ponds 
streams, by the mussels and a few minute forms, 
may be said with truth that the mussels of the Wes 
waters ape in their variety of forms, many of the | 
species. The entire class of Cephalopods, comprist 
squid, cuttle-fish, and nautilus, is exclusively marme. | 
extensive class of Crustacea, with the lobster, erab, 
shrimp as common examples, are represented in tresi 
by the crawfish and a few smaller species. As a slight 
pensation, however, the inland student has oftentimes * 
up in the rocks beneath his feet imperishable mementos 
ancient sea-life, and he may there find gigantic am 
huge masses of coral, and thousands of other forms ™ 
similar to existing species in the ocean. se
