forineentlige Aarde draetsredskaber og deres Mundinger (Stom- 

 ata) hos Slaegten Scutigera " (" The supposed respiratory organs 

 and their orifices (stomata) in the genus Scutigera"). Yid.Medd. 

 Naturh. Foren. Kjobenhavn, 1882, p. 88. 



At present, I will only point out that the number of stomata 

 is seven, and that of the pairs of spiracles in Lithobius six, 

 and that if the stomata were homologous with the spiracles in 

 the other Chilopods, certainly the first segment of the body in 

 Scutigera should have spiracles or coalesced spiracles, while that 

 segment in the other Chilopods should be without these respira- 

 tory organs. 



The limbs are very long, or much elongated, the different joints 

 being all, except the trochanter, elongated, and the last two, the 

 tarsus, being, besides, divided into a great number of little joints. 

 The first seven pairs of legs are nearly of the same length, but 

 each following pair increases in length, and the hindmost pair, 

 particularly in the male, is abruptly elongated into a fine hair. 

 The two joints of the tarsus are each divided into a great num- 

 ber of badly defined little joints, but the length and thickness 

 of the first joint is always greater than that of the second ; on 

 the contrary the number of little joints is much greater in the 

 second tarsal joint than in the first, and we find here even four 

 or five hundred such joints (Latzel, 1. c, p. 21). The length of 

 these little joints varies very much in the same species, nay, even 

 in the same specimen, and, besides, no established order can be 

 detected, so that we cannot possibly follow Newport, when he 

 makes use of the proportion between the lengths of the first two 

 of these little joints as characters of species. I have found the 

 proportion varying in the same species from 1:1 to 1:6, but 

 never have I seen the second joint larger than the first; also, in 

 the same specimen, I have found the proportion 3 : 1 in one leg, 

 but 1 : 1 in the other. Without going further, the circumstance 

 that the different authors who have used this character have 

 mentioned a different proportion in the same species demon- 

 strates that the proportion is not so fixed as Newport intimates 

 (1. c, p. 351). 



Each leg has a single claw, but this claw has two long setiform 

 processes, which run along the inner side of the claw, from the 

 base; the length of the processes seem to be from one-half to
