(Fig. 82). Male palpus: In Atypoides the conductor is composed of 
two sclerites (Fig. 57), an inner conductor sclerite, which tapers 
and contains the embolus distally, and an outer conductor sclerite , 
which lies outside and cradles the inner conductor sclerite. Macro- 
setae: A large thick seta, articulated in a well-developed socket, I 
shall call a macroseta. This is equivalent to the “spine” of most 
spider taxonomists. An enciform macroseta is one which tapers 
abruptly at its terminal end and is therefore rigid for its entire 
length. An attenuate macroseta is one which tapers gradually and is 
therefore very slender distally and easily bent. The four most lateral 
macrosetae on the ventral surface of the tibia in Figure 71 are enci- 
form, the two median ones attenuate. Spinnerets : The abbreviations 
AL, PM, and PL will be used to designate the following spinnerets 
respectively: anterior lateral, posterior median, and posterior lateral.

description. Carapace: Pars cephalica elevated above pars 
thoracica. Thoracic groove longitudinal. Eyes: Situated on slightly 
raised area (more prominent in males) which is steeply inclined an- 
teriorly. ALE largest, forming transverse or slightly procurved row 
with AME. Lateral limits of eye group formed by PLE. PME 
widely separated, close to their respective PLE. Sternum — labum: 
4 pairs of sigilla; ant. pair large, just behind labium, often indis- 
tinct; post, pair larger than second or third pair. Chelicerae : Robust 
with strong rastellar spines in female. Single row of large teeth 
(macroteeth) on mesal side of closed fang; much smaller teeth (mi- 
croteeth) on ectal side of post, portion of macrotooth row. Large 
apophysis projects anteriorly and dorsally from adult male chelicera; 
dense brush of large setae dorsally near distal end of apophysis. 
Pedipalps: Coxal endite quite small. Patella of male much shorter 
than tibia; tibia swollen. Outer conductor sclerite of male palpus 
wide, serrated on external surface, and curved in cross section so 
that it partially envelopes inner conductor sclerite. Distal portion of 
inner conductor sclerite heavily sclerotized, narrow, and envelops
