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. i. p. 334, BURMEISTER in OKEN'S 

 I sis, 1834, s. 134 138. Taf. i.) 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 larvae 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.

 up of a small dorsal lamina, semicircular, the second broader than 

 the rest, the last semicircular. Antennas thick, with the sixth joint 

 the largest. 



A. E} r es on both sides eight : seven disposed in a curved line, I 

 the eighth on the outside, out of rank. Joints of antennas seven,

 These animals resemble in external form some of the Oniscinea (Oniscus, I 

 Armadillo), and are even met with in apothecaries' shops, amongst the so- i 

 called Millipedes, mixed up with A rmadillo officinarum. Comp. on th< |j
