Turckheimia scelesta, O. P.-Cambr. loc. cit. p. 268, t. 39. figg. 10, 10 a—e (¢)*. 
Types, 2, in coll. Godman & Salvin. Total length 5:5 millim. 
Hab. Mexico, Teapa, Atoyac (H. H. Smith); Costa Rica, San José (Tristan and 
Biolley, ex Sarg *). 
The type of 7. scelesta has the vulva malformed, but is otherwise obviously identical 
with 7. diversa. This species bears a general resemblance to C. walckenaeri, but in 
the latter the abdomen is shorter, broader, more triangular, less compressed, and 
the tubercles less developed. ‘The scapus of the vulva is much shorter than in 
C. walckenaeri, and the basal portion is not bilobate. 
12. Cyclosa nodosa. (Tab. XLVII. fig. 11, ¢ .) 
Turckheimia nodosa, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 47, t. 4. figg. 11, 
lla,b(¢)’. 
Type, 2, immature, in coll. Godman & Salvin. Total length 8 millim. 
Hab. Guatemata, Chicoyoito (Turckheim'). 
The vulva of the type of this species is not developed, but the character of the 
abdominal tubercles renders it probable that C. nodosa will prove to be specifically 
distinct (see table and Plate). 
13. Cyclosa index. (Tab. XLVII. figg. 12, 12 a-c, 2.) 
Cyclosa index, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 51, t. 6. figg. 6, 6a-c (2); 
Banks, Proc. Calif. Acad. Sci. (3) i. p. 256’. 
Type, Q, in coll. Godman & Salvin. Total length 5 millim. 
Hab. Lower Catirornta (fide Banks *)—Guatemata, Tamahu, Coban, Cubilguitz 
(Sarg *). 
It is impossible at present to decide whether C. turbinata, McCook, C. caudata 
(Hentz), and C. index, O. P.-Cambr., are identical or not; and for the time being I 
leave the examples of C. index before me under the name they were described. ‘They 
can be distinguished from C. clara by the longer and more pointed tubercle at the apex
