78 ARANEIDEA. 
limit of the epigynal area, The position of the orifices and the general character of the spermathece are 
probably fairly constant, otherwise the conformation of the vulva is liable to individual variation. 
Hab. Mexico, Teapa (H. H. Smith). 
4. Trachelas spinulatus, sp.n. (Tab. VI. figg. 3, 3a, 6 .) 
Type, d, in coll. Godman & Salvin. : 
Total length 6 millim. 
d. Colour the same as in 7’. transversus, and the abdomen with a dorsal scutulate area. 
Structure similar to that of 7’. transversus, except that the mandibles are more deeply excavate beneath on 
the inner margin. 
Palpus: tibia (in profile from outside) scarcely broader at the apex than at the base, about one-fourth longer 
than broad ; apical spur shorter than in 7’. transversus and not curved upwards. Apex of bulb terminating 
in a short simple spine, whose apex is directed inwards. 
Hab. Guatemaa (Sarg). 
5. Trachelas spirifer, sp.n. (Tab. VI. figg. 4,4, ¢.) 
Type, ¢, in coll. Godman & Salvin. 
Total length 6-5 millim. 
¢. Carapace and mandibles dark mahogany-brown. Legsi. and ii. orange-brown, iii. and iv. paler. Abdomen 
olive-brown. Sternum mahogany-brown. 
Carapace rugulose-impunctate. Sternum slightly longer than broad, shallowly rugulose. Mandibles excavate 
on the inner margin. Lower margin of fang-groove with two teeth. Maxille evenly rounded on the 
external apical margin. Tibia i. cuspulate beneath the apical half, at most; tibia ii. sparsely cuspulate 
beneath the apex. Protarsi and tarsi i. and ii. cuspulate beneath and with a slight scopula. Abdominal 
dorsal region not scutulate. Posterior row of eyes strongly recurved; centrals one and a half diameters 
apart, two and a half from laterals. Anterior row procurved ; centrals two-thirds of a diameter apart, 
three-fourths from laterals. Clypeus less than one diameter of an anterior central eye. Leg iii. without 
anterior marginal row of tubercles. 
Palpus: tibia one-half longer than broad, with a short spur on the outer side directed downwards. Bulb 
basally inflated, terminating in a spiraloid lamellular process, with a fine sinuous-uncate apex. 
Hab. Guatema.a (Sarg). 
6. Trachelas bulbosus, sp. n. (Tab. VI. figg. 5, 5a, 8,6 ; 6,2.) 
Type d, cotype 2, in coll. Godman & Salvin. 
Q. Total length 7 millim. 
g. Carapace and mandibles mahogany-brown, sternum a little paler. Legs i. and ii. orange-brown ; iii. and 
iv. paler. Abdomen olive-brown, with the four normal muscular scars. Abdomen with a scutulate 
dorsal area. 
Carapace rugulose-impunctate. Sternum one-fourth longer than broad, smooth. Mandibles excavate on the 
inner margin. Lower margin of fang-groove with two teeth. Maxille evenly rounded on the external 
apical margin. Tibie i. and ii. cuspulate beneath the apex only. Tarsi and protarsi cuspulate beneath 
and bearing a thin scopula. Leg iii. without any anterior marginal row of tubercles. 
Posterior row of eyes strongly recurved, centrals two diameters apart, two and a half from laterals. Anterior 
row only very slightly procurved; centrals half a diameter apart, half a diameter from laterals. Clypeus 
less than one diameter of an anterior central eye. 
Palpus : tibia scarcely longer than broad, with a small spur on the outer apical margin directed almost straight 
forwards. Bulb very much inflated at the base, with a broad sinuous lanceolate spur at its apex. This 
spur is somewhat similar to that of 7’. lanceolatus, but is less sinuous, broader, and closer to the apex of 
the tarsus ; the bulb is also much more attenuate, while the tibia is twice as long as its breadth.
