the Indian and American seas: tlie body is of' a 
pale yellowish colour, beautifully variegated with 
red streaks and specks: the sides of the thorax are 
marked by several transverse jdeats, and the front 
notched into four obtuse denticulated divisions. 
Among the Cancri macrouri or long-bodied 
Cancri the common I.,obster may serve as a fami- 
liar example. This species, as every one knows, 
is found in great plenty about many of the Eu- 
ropean shores: its colour, when living, is a fine 
blueish black, beautifully variegated on different 
parts with paler spots and clouds. Its general 
habitation is in the clearest water, about the foot 
of such rocks as impend over the sea. Lobsters 
begin to breed in the spring, and continue breed- 
ing during part of the summer: they deposit their 
eggs in the sand, where they are said to be soon 
hatched: it is observed however, that those which 
are cast before the warm season seldom arrive at 
perfection. In the months of July and August 
the young may be observed in great numbers in 
the little pools left by the tide among the rocks: 
when recently hatched, they have an ajjpearance 
distantly resembling that of tadpoles, but gradu- 
ally obtain the form of the complete animal. 
Cancer Norvegicus, a native of the northern 
seas, is of a more lengthened or slender form than 
the Lobster, and with thinner claspers in propor- 
tion, of an angular shape, and roughened by 
strong protuberanees along the angular elevations. 
Its natural colour is said to be pale red, Avith 
yellow markings or variegations.
