THE HORSE FOOT CRAB. 
BY REV. S. LOCKWOOD, PH. D. 
— ÀÁ9—— 
Ir is proposed to give some results of a summer's study 
on the ineubation of the eggs of the Horse Foot Crab, and 
to connect those results with observations made in an ac- 
quaintance of several years with the animal in its native 
haunts, in the hope of thereby furnishing something towards 
a life-history of the species." . 
Among systematists this crustacean is known as Limulus 
Polyphemus. It bears also the popular names Horse Foot 
Crab, Horseshoe, and King Crab. In this article these 
names will be used as convenience may suggest. 
The King Crab delights in moderately deep water, say 
from two to six fathoms. Except in the case of the very 
young, which are probably carried thither by the tidal flow ; 
*In October, 1869, the writer read a paper before the Zoological section of the New 
York Lyceum of Natural History, under the title “ A Contribution to the Natural His- 
tory of the King Crab," which contained the notes taken during su investi- 
. gation alluded to above. The article now appearing in the AMERICAN NATURALIST is 
taken mainly from that paper. — S. L.
