Aspis; Fig. 1B-D; Pl. 1a, e): A pair of oval weakly-sclerotized areas anterodorsally marks the positions of the retracted chelicerae. The ventral margin of the aspis is reflexed to form the aspal rim (a.r.) and there is a distinct lateral ridge (l.r.). The bothridium (b.) has an inner multi- chambered wall and a smooth outer one from which three finger-like chitinous tracheoles arise and are directed mid-dorsally. The margin of the bothridial aperture is thickened (as shown by the arrow in Pl. le) and fianked posteriorly by a pronounced scale. There are three pairs of procum- bent dorsal setae, the rostrals (ro), lamellars (la) and interlamellars (il), and two pairs of setae laterally, the exobothridials (ex) and the sensilli. In most of the species examined, setae il and la are located at the level of the bothridia, la being somewhat shorter than il. The sensilli are variable in form and so provide a useful taxonomic feature. In some species they are short, ovate or lanceolate while in others they are long, narrow and tapering. The sensillar margin may be serrated (Pl. 1a) and in

it bears a number of straight-edged teeth sub- terminally. The sensillus is most easily observed in scanning electron micrographs as in flattened slide preparations its appearance can depend very much on orientation.

Notogaster (Fig. 1A, E; Pl. 1e): The anterior margin of the notogaster is well sclerotized and, following Jacot (1930), can be subdivided into three regions: the thickened collar (C), the pseudo-stigmatic [sensillar] notch (N) (Pl. 1e) and the lappet (L) which projects somewhat anteriorly. Of the 15 pairs of setae, 14 are regarded as being homologues of c1-3 and cp, d1-2, e1-2, h1-3 and ps1-3 of the holotrich nomenclature, and the additional seta as ps4. The distributional pattern of notogastral setae is essentially similar in all the British species but the relative lengths and attitudes of the setae vary considerably from one species to another. The vestiges of setae (f1) and (f2) are thought to be represented by two pairs of subcuticular structures located posterolaterally (Grandjean, 1950). Vestigial f1 normally lies between setae h1 and ps1 and f2 between setae h1 and h2 but in certain small species (for example,

|
) f1 is closely associated with the seta h1. There are four pairs of prominent subcuticular fissures: the anteriors (ia) and medians (im) are situated just posterior to seta cp while the posterior pleurals (ip) and infrapleurals (ips) (when present) are situated on either side between setae h2 and h3 and between setae ps3 and ps4, respectively.

Two anal setae an1-2 are located on the paraxial margin and three adanals ad1-3 submarginally; setae ad1-2 are often vestigial. Each anal plate has a prominent hood-like lobe located ventro-anteriorly on its paraxial margin and in the so-called 'left fitting' arrangement (van der Hammen, 1963) the lobe on the right-hand plate overlaps that on the left-hand plate while in the 'right fitting' arrange- ment (as shown by the arrow in Fig. 2E) the reverse is true. Van der Hammen has suggested that the arrangement of these interlocking lobes and the condition of setae ad1-2 (present or vestigial) could be useful taxonomic features. This view is not, however, supported by the present study since these two features have been found to exhibit considerable intraspecific Variation.</paragraph>

The furrow bears a single aggenital seta ag1 antiaxially (Pl. 1b). There are nine genital setae arranged in two rows. The anterior five setae g1-5 are minute and located on the paraxial border while the posterior four setae g6-9 are moderately short and submarginal. There are three pairs of genital papillae (g.p), the anterior pair being rather small. Elongate oval structures have been observed inside the genital papillae and these may prove to be spermatophores. The first two pairs of genital papillae border the ovipositor, which, when fully extended, can be seen to be a rather short tube divided into a distal and a proximal portion by a weak circular constriction.</paragraph>

This complement will be referred to as the 'complete chaetotaxy type' (Figs 4; 5). On tarsus I only 16 of the 20 setae regarded by Grandjean (1940) as being characteristic of 'higher' Oribatei are present, the primilaterah and postlarvals always being absent. Four setae Surround the base of the claw, namely, a dorsal pair of prorals (p) and a ventral pair of unguinials (u). Three pairs of setae are located posterodorsally to the prorals: the iterals (it), tectals (tc) and fastigials (ft). Ventrally, behind the unguinials, there is an unpaired subunguinial seta s and a pair of primiventral setae (pv).

Furthermore, the tarsal setae exhibit considerable variety in form. On tarsus I six of the setae (s, (it), (p) and a') are hollow eupathidia. On all four tarsi setae (ft) and (pv), together with a" on tarsi I and II, are generally more or less straight, circular in section and bear two or three rows of lateral serrations.

, a species he recorded from rotting wood in his cellar at Perigueux, Dordogne, France. By Clearing whole and dissected specimens (Grandjean, 1949) he was able to observe the patterns of setae on the body shields (Grandjean, 1933, 1934 & 1950), which provided new criteria for the identification of species of this genus. Hitherto, species differentation had been based almost entirely on body shape and colour, two characters now known to be uniform in many
