114 ARANEIDEA. 
16. Ctenus ensiger, sp.n. (Tab. VIII. figg. 10, 10a, 6, ; 11, 2.) 
Type ¢, cotype 2, in coll. Godman & Salvin. S 
Total length, ¢ 7, 2 10°5 millim, / 
3 @. Carapace orange-brown, with two longitudinal dusky bands ; legs, sternum, and mouth-parts orange- 
brown; mandibles darker. Abdomen dull brown, mottled and marked with sooty-black spots; a 
conspicuous double series of six or more runs down the dorsal area, more noticeable in the male. 
Carapace almost level, in profile, slightly gibbous behind. Second row of eyes straight by the anterior margin. 
Ocular quadrangle broader than long, distinctly narrower in front ; anterior central eyes distinctly smaller, 
less than half a diameter apart. Clypeus equal to one diameter of an anterior central eye. Structure of 
the female similar in general characters to that of the male. 
3. Palpus: tibia with a long curved ensiform spur on the outer side, directed straight forward, its apex 
abruptly curved upward, forming a small hook. The palpal organs consist of a bulb having a lamelliform 
process at its base, the seminal duct running across in a sinuous course, about the middle, with a second 
small lamelliform process at its apex, and a short sinuous black spine, its point lying over a semitransparent 
racquet-shaped process. 
A figure of the vulva of the female will be found on the Plate (Tab. VIII. fig. 11).

17. Gtenus convexus, sp.n. (Tab. VIII. fig. 12, 2.) 
Type, 2, in coll. Godman & Salvin. 
Total length 20 millim. Carap. 10x 7:5. Legs: i. 38; ii. 365; iii, 32; iv.42:5. Pat. -+tib. i. 12:25; 
iii. 10; iv. 12°75. 
Q. Carapace and legs mahogany-brown, clothed with grey pubescence. Abdomen brown, with a central 
scalloped pale band. Underside with two longitudinal pale bands. 
Carapace slightly raised behind, in profile. Second row of eyes procurved, the posterior margin of the laterals 
falling well behind the anterior margin of the centrals. Ocular quadrangle a little longer than broad, 
slightly narrower in front; anterior central eyes distinctly smaller than the posterior central. Clypeus 
equal to one and a half diameters of an anterior central eye. 
Hab. GuateMata (Sarg). 
This species is closely allied to C. sinwatipes, but the form of the vulva is quite 
distinct.

—Hab. MExico. 
I am unable to identify this species. It is very likely a Cupiennius.
