and bionomics of Diplopoda, the author gives diagnoses of the families 
(Polvxenidae, Glomeridae, Polydesmidae, Chordeumidae, and Iulidae), of the 
genera, and of the species in Ehenish Prussia. A chapter is devoted to 
the numerical relations of the sexes, and another to the physiological 
grouping of the species as they occur in soil, under stones, under bark, 
and so on, ten groups being recognised. The author then discusses the 
ScJialtstadium in the life-history of male Iulidae, and ends with a biblio- 
graphy. 
Bohemian Diplopoda.* * * § — Dr. B. Nemec describes a new variety of 
Craspedosoma Bawlinsii, lulus ( Leptoiulus ) proximus sp. n., lulus (Micro- 
podoiulus ) ligulifer Latz., lulus ( Leucoiulus ) coerulans sp. n., and a new 
minute form of Polyzonium germanicum. 
Hew Indo- and Austro-Malayan Diplopoda. + — Mr. E. I. Pocock de- 
scribes 7 new genera and 26 new species of Platyrrhachidae, — millipedes 
of large or medium size, in which the body is composed of 20 segments-, 
each segment (except the first and the last) being furnished on each side 
with a large more or less square and horizontal plate which bears the 
pore. 
Algerian Iulidse.* — H. W. Brolemann describes the five species 
collected by Lucas in 1846 : — ScTiizophyllum (Bothroiulus) fusco-uni - 
lineatum , S. ( Apareiulus ) lapidarium, lulus ( Phalloiulus ) distindus i, 
I. ( Phalloiulus ) algerinus sp. n., I. ( Anoploiulus ) africanus sp. n. He 
concludes that the Algerian Iulidae, though distinct, exhibit incontest- 
able bonds of relationship to pahearctic forms. 
S. Arachnida. 
African Solifugse.§ — Mr. E. I. Pocock distinguishes three families i 
— Hexisopodidae nov., Galeodidae s.s., and Solpugidae s.s., the last in- 
cluding two sub-families — Solpuginae nov. and Ehagodinae nov. He 
describes seven new species from tropical Africa. From reports by 
Mr. G. A. K. Marshall, some interesting notes on habits have been 
compiled. The noise attributed to stridulation seems more probably 
due to trituration. The terminal organ on the palp is, as Hutton ob- 
served, a sucker. It seems to be used in grasping the prey and convey- 
ing it to the mandibles. Termites form an important part of the food- 
supply of some species. The very rapid pace, e.g. of Solpuga sericea y 
like blown thistledown, is rarely kept up for more than a minute. 
Development of Pedipalpi.fi — Mdlle. Sophie Pereyaslawzewa de- 
scribes the k state of the embryos of PJirynus medius Herbst just before 
hatching. Among the points noted are the following : — The segmenta- 
tion, having attained its maximum, is beginning to disappear ; while the- 
cephalothoracic muscles are striped, those of the abdomen are all smooth 
there is evidence of a local ectodermic proliferation preceding the de- 
velopment of the lung-books; there are hints of the formation of 
pulmonary structures in the adjacent segments; besides the stigmata,.
