apertures, which form a row on each side of the body, to be air-slits 
(stigmata). The true air-slits lie quite beneath, near the insertion 
of the feet, (Savi op. cit. Tom. 1. p. 334, BuRMEISTER in OKEN’S 
Isis, 1834, s. 134—138. Taf. 1.) These animals can roll themselves 
up spirally, with the head in the middle; in which posture they 
pass the winter. In copulating they bring the anterior part of the 
body in which the sexual organs are situated (in the female in the 
fourth, in the male in the seventh ring), perpendicularly upwards ; 
the posterior part of the body rests tortuously on the ground. In 
the spring the female deposits her eggs in masses of sixty or 
seventy in a hole excavated for the purpose under the ground ; after 
three weeks or more the young make their appearance, but still 
continue to adhere for some days by a string to the shell, which has 
burst longitudinally, without motion, and surrounded by a proper 
membrane ; at that period they have no legs at all; as soon as 
they have got three pairs of feet, they separate themselves from the 
shell; they have now a great resemblance to the larve of some 
Coleoptera ; soon the number of rings and feet begins to be increased 
in that part of the body which is seated in front of the penultimate 
ring.

Ins. Heft 162, No. 7. Some foreign species attain a length of five inches and 
more, as Spirotreptus javanicus BRANDT, and Spirobolus spinosus DE Haan, 
Mus. Lugdun. &c. The last species, from New Zealand, is black, with 
different rows of spines running longitudinally. 
Glomeris LATR. Body elongato-oval, gibbous above, plane or 
concave below, contractile into a ball, with the first segment made 
up of a small dorsal lamina, semicircular, the second broader than 
the rest, the last semicircular. Antenne thick, with the sixth joint 
the largest. 
A. Eyes on both sides eight ; seven disposed in a curved line, 
the eighth on the outside, out of rank. Joints of antenne seven, 
the penultimate including the last. Sub-genus Glomeris BRanpt.

These animals resemble in external form some of the Oniscinea (Oniscus, 
Armadillo), and are even met with in apothecaries’ shops, amongst the so- 
called Millipedes, mixed up with Armadillo oficinarum. Comp. on the
