(sec. Simon). 
8. Eurypelma spatulatum, sp.n. (Tab. I. figg. 19, 194, b, 3.) 
Type, ¢, in Brit. Mus., ex coll. Keyserling. 
gd. Length —? Carapace 18x17; abdom.?; sternum 7X5°5; coxa of pedip. 7x4; mandible 8 millim, 
Legs ???? Ocular tumulus 2x 2, anterior margin to fovea 12, fovea to posterior margin 5:5 millim. 
g. Carapace, sternum, abdomen, and legs dark ferruginous-brown, clothed with sandy-grey pubescence and 
long hairs. Leg i. has on the femur outside a long lanceolate pale band and two narrow sandy-grey 
dorsal lines. Patella with two pale lanceolate bars enclosing a similar brown bar. Tibia with two pale 
narrow dorsal grey bars; base of protarsus with a short, central, narrow pale bar. (In all probability all 
four pairs of legs are similarly marked, but some are missing.) 
Carapace a little longer than broad. Cephalic area occupying more than two-thirds the length of the carapace. 
Eye-tumulus as long as broad; central portion raised, bearing anterior central eyes. Anterior row of 
eyes procurved; longitudinal axis of laterals a little longer than the diameter of the centrals; centrals 
one diameter apart, half a diameter from laterals. Posterior eyes almost contiguous; centrals smaller ; 
laterals oval, one-half their longitudinal axis from anterior laterals. Sternum longer than broad. 
Sigilla 8, submarginal. Labial plate a little longer than broad, its apical third area studded with 
numerous cuspules. Basal anterior angle of the coxa of the pedipalp similarly studded; distal anterior 
angle slightly produced. Legs: Protarsus i. curved (in profile) at the base, as long as the tibia. Inner 
apex of tibia i. with two spurs beneath ; outer spur long, slender, curved upwards and slightly inwards, 
with a few cusps and a short conical tooth at the apex; inner spur shorter, but slender. 
Tarsi and protarsi i. and ii. scopulate to the base. Tarsi iii. and iv. scopulate to the base. Protars us ili 
scopulate to the base; iv. scopulate for one-fourth its length at the apex. 
Legs spinose, especially the tibiee: and protarsi iii. and iv. beneath. Protarsus iv. as long as the tibia and half 
the patella. Tarsal claws 2, with 5-6 minute separate denticules beneath. 
Palpal bulb, seen from outside, elongate-piriform, concave-spatuliform towards the apex, attenuate and finely 
aculeate at the apex itself, slightly curved and directed forwards. The outer margin of the spatulate 
portion forms a distinct carina; seen from in front, elongate-piriform, straight, the apex sinuo-spatuliform- 
aculeate, scarcely curved outwards. 
Hab. Mexico (Mus. Brit., ex coll. Keyserling).

Eurypelma rusticum, E. Simon, Ann, Soc. Linn. Bord. xliv. pp. 323°, 334’. 
Type, ¢, in coll. E. Simon, Paris. 
3g. Total length 35 millim. Carap. 15x13; ceph. area 10. Legs: 1.57; ii. 52; iii. 49; iv. 61—i. fem. 14, 
pat. 6:5, tib. 10°5, prot. 10, tars. 6-5—iv. fem. 13-5, pat. 7, tib. 11, prot. 14:5, tars. 8. 
The colour of this form is the same as that of the majority of the species of the genus; while the hairs on the 
legs are intermediate in length between those of the extreme forms. Tarsal claws toothed.
