(Fig. 35). The epimera 1 form a V. Curions is the genital 

 opening, shut by two valvules, resembling strongly those in Ori- 

 ùa/idae. On each genital cover a lunular chitinization posteriorly 

 is visible, the signification of which is not clear to me. In fig. 36 

 I have drawn the genital covers; when sinking the tube of the 

 microscope, two genital suckers are scarcely visible outside of the 

 lunular chitinizations ; they seem to be very small, rudimentary. 

 Fig. 37 gives us a side view of the animal. — Legs. The legs 

 of the female, especially those of the 3d and 4th pair are much 

 more Gl^ci/ß/iaffus-Wke than those of the male. Curious is the 

 cup-shape of the trochanter, femur, genu and tibia of the fore-legs. 

 The femur 1 bears distally a pectinated hair (fig, 35); the genu 

 1 two (fig. 34) and the tibia 1 one (fig. 35). The femur 2 one 

 (fig. 34) and the tibia 2 one (fig. 34). Th legs 3 and 4 are .slender 

 and of the type of Gl. domes ficus.

JiemafTis. 1. Hereabove I have already mentioned a few features 

 which I'emembei' us of Orihatidae. There are more; viz.: the cup- 

 shaped articles of the legs in the female, and a forming of so-called 

 teciopedia in tlie female (see fig. 35). 



2. Kramer has first described a bifid feathered hair between the 

 coxae 1 and 2 in his Glyci/phagus ornatus (1881 , in Z, f. d. ges. 

 Naiurw. v. 54. p. 435). Then Michael delineated the same of 

 Gl. plati/gaster (1886, in J. Linn. Soc. v. 19. p. 275, t. 34). 

 I have observed this hair in more species of Tyroglyplddae. Kramer 

 thought it protecting a longitudinal slit or stigma. I think Kramer 

 is partly wrong; the hair itself, or the thin skin covering 

 the slit may breath, but there is no hole. The above described 

 species (see fig. 35) has a hair between the head and the coxae 1 

 and between coxae 1 and 2 , and this hair is bent ventrally and 

 backward. 



3. This is the ^acarien (fig. 28 et 30), qui n'' appartient à aucun 

 des genres précédentsy> of Troupeau (Bulletin de la Soc. d'Angers 

 V, 6, 7, 1876—77, fase. 2, paru 1878, p. 115).
