Cephalad, theoviducts unite to form a common uterus (m), which opens into thevagina (fig. 54, v). The vagina opens mesally through the vulva v^hichis located near the cephaloventral margin of the epigastric furrow {ef)..

This basic organiza-tional pattern is common to all female spiders. COPULATORY SYSTEM An urgent need exists for a comprehensive study of the copulatorysystem of female spiders, with at least an effort at standardization ofterminology. Comstocks work (1910) on the palpi of male spidersdid much to unify and clarify nomenclature pertaining to those struc-tures. As Blauvelt (1936, p. 92) stated the early authors mention theorgan but do not describe it with sufficient accuracy to clarify theirterminology. Menge especially was given to the use of several namesfor each part, and was rather indiscriminate in his application of (loc. cit.) justifiably attributed much of the confusion innomenclature to the unquestioning adoption of th
