AUACHNIDA. 
DatameSj closely allied to Glavia^ differing chiefly in the dentition of 
the falces, the armature of the metatarsi of the fourth pair of legs. The 
fang of the falx is also fixed, unarmed, and straight, the “flagellum” 
being represented by a fascia of hairs. D. sulfureus, p. 142, Colorado, 
and calif ornicuSj p. 143, pi. iii. fig. 37, California. Id. 1. c. 
Cleobis differs from other genera in the elongated, lozenge-shaped 
caput, the legs slender, but the femora of the fourth pair enlarged and 
compressed, as though for the purpose of leaping. C. saltatrix^ p. 146, 
pi. iii. figs. 32-36, Mexico.

dentition of the falces. Type, M. variegata, P. Gerv., p. 151, pi. iii. figs.

PHALANGIIDEA. 
The species of this Order (Opiliones, Sim.) are divided by E. Simon, 
Arachn. de France, vii. pp. 116-142, into three Sub-orders : i. Cyphopii- 
TiiALMi ; ii. Mecostethi ; iii. Plagiostetiii. TheMECOSTETiii chiefly 
found in exotic regions; the Plagiostetiii in temperate countries. The 
Cypiiophthalmi, including a few types only (both exotic and European) 
separated from the Mecostethi by several important characters. \_Cf. 
A. Strecker, Arch. f. Nat. 1876, p. 293, pis. xvii.-xx.] 
Cyphopiithalmi, represented in France by one family only, Sironidte, 
containing two species. Siro rubens, Latr., S. corsicus, E. Sim., pp. 
141-146, pi. xxii. figs. 9-14. 
Mecostethi represented in France by one family, Phalajig[i]odi(bVy 
containing 6 species of the genus Phalangli^odes, Tellkampf, pp. 147-156, 
pi. xxi. figs. 1 & 2, pi. xxii. figs. 1-8. 
Plagiostetiii, divided into four families : i. Phalangiidce, containing 
(in France) 11 genera and 61 species, pp. 157-265; ii. Ischyropsalidwy 
containing 2 genera and 7 species, pp. 265-277 ; iii. Nemastomatidee, con- 
taining 1 genus (Nemastoma) and 8 species, pp. 277-289 ; iv. Trogulidce y 
containing 6 genera and 16 species, pp. 289-311, pis. xxi. (pt.), xxii. xxiii. 
& xxiv.
