localities from which it has been recorded, however, are as 
‘yet few in number. It is recorded by Thomas Edward from 
Banff! Mr David Robertson records it from Kilwinning, 
Ayrshire, from which place specimens were sent to him by 
Mr John Smith,? and it is moderately common under stones 
at Salisbury Crags. Armadillo differs from all the other 
land Isopods by the form of the uropods, which are broad, 
truncate, and do not extend beyond the extremity of the 
pleon, so that the posterior end of the animal presents an 
even rounded outline. When alarmed it rolls itself into a 
perfect ball, the antennz being entirely concealed. The cara- 
pace is smooth and polished, and the colour is very variable, 
but is usually a dark steel-grey mottled with white. Some 
specimens are very light coloured, while others are almost 
black. In ‘‘former times the Armadillo was highly reputed 
for its supposed medicinal virtues.” “When dried and 
pulverised” these creatures were, according to the old books 
of materia medica, “highly celebrated in suppressions, in all 
kinds of obstruction of the bowels, in the jaundice, ague, 
weakness of sight, and a variety of other disorders. And, 
moreover, the wine of Millepeds—prepared by crushing these 
animals when fresh and infusing them in Rhenish wine—was 
considered an admirable clearer of all the viscera, yielding to 
nothing in the jaundice and obstructions of the kidneys” (see 
Fitch, in “ Report on Noxious, Beneficial, and other Insects 
of the State of New York,” Albany, 1855). It thus appears 
that sclaters have not always been treated with so much 
neglect as they seem to be now, though it may be questioned 
whether they considered the attention they received in these 
early days a matter for congratulation: possibly, like some of 
their more highly organised fellow-creatures, they prefer 
obscurity with its accompanying peace, safety, and content- 
ment, rather than the condition of being “ highly celebrated ” 
and “pulverised.” There is a species of millipede—Glomerus 
marginatus—that may easily be mistaken for the Armadillo; 
the carapace has apparently the same number of segments,
