THE SLOW SHRIMP. 
The Spiny Lobster' is also called the Sea Cray-fish, or the Red Crab. Its claws are 
very small, and by no means formidable. It is mostly found on the western and southern 
coasts, and is caught in crab -pots, like the common lobster. Its flesh is good and well- 
flavored, though rather tougher and coarser than that of the lobster ; moreover, the want of 
the claws is a drawback to its excellence, so that it is not esteemed nearly so much as the true 
lobster. Sometimes it is found entangled in the nets, and even upon the fishermen’s lines. 
The average length of this species is eighteen inches, and its weight about five pounds, 
when adult. Its color is purple-brown, with some irregular white spots, and its legs are red- 
dish-white, banded longitudinally with brown. One species of this genus,. Palinurus orna- 
tus , sometimes attains to an enormous size, measuring from the end of the antennae to the tail 
rather more than four feet. 
The Spiny Lobster is abundant on the Florida Reef, and there serves as a tolerable sub- 
stitute for the Lobster, which does not inhabit south of New York. It is called Craw-fish at 
Key West. As an edible it lacks the pleasant flavor of the former, being more like the com- 
mon edible crab. 
The Lobster of America inhabits from St. Lawrence River to New York State. For- 
merly, the specimens obtained for the markets were of good average size of eighteen inches. 
They are now reduced to smaller numbers, and one a foot in length of body is rare. Legis- 
lation has become necessary for the protection of this most useful and highly-prized food 
crustacean. 
The two next examples belong to a family called the Thalassinidse, in which the abdomen 
is long, its integuments rather soft, and the carapace small and compressed on the sides. 
The first one, the Mud-Ritrrower, is not very often seen, as it lives in a burrow some 
two feet under the surface of the mud. It forces itself beneath the mud by means of the third 
pair of legs, and there passes the greater portion of its time. The shell of this species is very 
thin, and but for the enormous claw with which it is furnished it would seem quite a helpless 
creature. 
One species of this genus, the G-reat Burrowing Crab ( Callianassa major), inhabiting 
Florida and other parts of America, forms a very remarkable burrow. Mr. T. Say, wdio found 
this creature by digging in the sand, gives the following account of its habits: “It had 
formed a tubular domicile, which penetrated the sand in a perpendicular direction to a consid- 
erable depth ; the sides were of a more compact consistence than the surrounding sand, pro- 
jecting above the surface about half an inch or more, resembling a small chimney, and rather 
suddenly contracted at top into a small orifice. The deserted tubes of the Callianassa are in 
many places very numerous, particularly where the sand is indurated by iron into the incip- 
ient state of sandstone ; they are always filled up, but may be readily distinguished by the 
indurated walls and summit often projecting a little above the general surface.” 
The Mud-burro wer is rather a pretty little creature, being of a soft pink hue, sometimes 
changing to yellow on the sides. Very soon after death these colors fade, and change into 
dull gray. The haddock seems to feed largely on this species, as fragments are mostly found 
in the stomach of the fish. 
The second species is the Slow Shrimp, a rather curious looking creature, much 
resembling the common shrimp, except that it possesses a pair of large and stout claws. Its 
popular name is derived from the sluggishness of its movements, as it has scarcely any idea of 
running or swimming away if alarmed, but only attempts to escape by burrowing in the mud. 
If, therefore, it should be intercepted upon some harder ground, where it is not able to 
burrow, it exhausts all its strength in unavailing efforts, and is easily taken prisoner. The 
best way of obtaining this creature is to dig it out of the sand. It is but a small species, 
measuring about three inches in length. Several other burro wer s are inhabitants of the 
European shores. One of them is the Mud-borer ( Gtbia stelldta ), a small species, measuring 
about two inches in length. This creature often takes possession of the burrows which have 
been made and forsaken by the razor-shell, but it is doubtlessly able to bore holes for itself. 
It is rather a pretty little crustacean, being of a pale yellowish- white, covered with very little
