DEVELOPMENT AND PHYTOGENY—NEW SPECIES. Mljr. 3 
Bergh (1) and Sedgwick (21 and 22) also describe the development of 
Peripatus. The latter (22) describes certain facts in the development of 
P. capensis, which, “if generally applicable, reduce the adult body to a 
syncytium—to a multinucleated vacuolated protoplasmic mass, and 
embryonic development to a multiplication of nuclei, and a specialization 
of tracts in this mass.” 
Scudder (20) gives a resume of all that is known as to the geological 
history of Myriopods, and discusses the relationships between the several 
groups. 
Anatomy. 
Bourne (2) describes certain points in the anatomy of Sphcerotherium. 
There are the three extra pair of appendages, copulatory in function ; 
two pairs of these bear chitinous ridges, which being rubbed against 
similar ridges on the inner surface of the terminal tergite, act as a stridu- 
lating organ. The trachese resemble those of the Chilopoda rather than 
of the Chilognatha , but this fact is due to homoplasy, not to homology. 
The antennary sense-organs are conspicuous, and are described. Ali¬ 
mentary tract is curved as in Glomeris. A special sense-organ in the 
head, similar to that described by Leydig in Glomeris , is probably audi¬ 
tory. 
Carmichael (4) describes the alimentary system in Litliobius and 
Geophilus. 
Chalande (5) describes the respiratory system in certain French 
Chilopods. In Himantarium aud Geophilus there is a pair of stigmata in 
each segment, except the cephalic and two anal segments ; the tracheae 
forming two distinct networks. In Litliobius there are six pair of stig¬ 
mata on segments 3, 5, 8, 10, 12, and 14; in Cryptops and Scolopendra, 9 
pairs on these segments and segments 16, 18, and 20. In Scolopendra the 
tracheae anastomose, and form a single network ; in the other two genera 
there are two networks. 
Heathcote (15) describes an auditory organ in Scutigera. 
Tomosvary (24) describes the secreting glands of the ventral surface 
of Geophilus. 
Gaffron (9) describes the reproductive organs of Peripatus edvmrdsii. 
Richard (19) describes the phosphorescence of Scolioplajies crassipes , 
Koch. 
Haacke, W., (11) notes that an Australian species of Scutigera uses its 
long legs to form a trap to catch flies.
