304 ARANEIDEA. 
anterior extremity of the upperside; these are followed by several transverse narrow curved bands or 
stripes of a less clear white than the spots, but all with a narrow marginal line, both before and behind, 
of a vermilion colour, which colour also suffuses a space at the hinder extremity round the spinners. 
The female resembles the male in general form and character; but the legs are shorter, and the characteristic 
spines are on the tibie of the first two pairs, as well as on the metatarsi, and the middle spine of the 
three long ones on the metatarsi of the second pair is more nearly equidistant from the other two. 
The maaille, labium, and sternum are dark yellow-brown. 
The abdomen is similarly marked to that of the male; but there seems to be considerable variation in the 
extent and distinctness of the markings in different examples, and the suffusion round the spinners is 
deeper in hue and takes a more regular form, having three strong prominent points above and underneath, 
and extending in front of the spinners along the underside of the abdomen. The colour of this also 
varies from dull vermilion through rust-red to brown; probably a series of specimens would show similar 
variations in the male. The genital aperture is of characteristic form, but has a general resemblance to 
that of G. zonatus. 
Hab. Guatemata (Sarg: 3); Panama, Bugaba (Champion: 9 ). 
Gelanor medius, sp. n. 
Adult male, length 23 lines; adult female, length 23 lines. 
This spider is very nearly allied to G. miatus, and resembles it closely in colours and markings. 
The cephalothorax is yellow, tinged with yellow-brown. 
The eyes of the posterior row form a distinct curve whose convexity is directed backwards. The central 
quadrangle is but little broader than long. 
The legs are long, slender, 1, 2, 4,3. Colour yellow to yellow-brown on the femora and genuz; a tolerably 
well-defined annulus at the fore extremity of the tibia and the metatarsi of the first pair yellow-brown. 
The femora of the first pair have a well-defined dark longitudinal line along the inner side. Armature as 
in G. mixtus. 
Palpt long, slender ; colour yellow-brown, deepening to dark reddish-yellow-brown at the lower half of the 
humeral joint and the anterior half of the radial joint. The form of the digital joint is very irregular, 
but differs distinctly from that of G. mixtus, as also do the form and structure of the palpal organs. 
Falces, maxille, and sternum similar in colour to the cephalothorax. Labium tinged with brown. 
Abdomen similar in general pattern to that of G. mixtus, but the white spots on the fore part are much smaller 
and of a kidney-shape, and, as well as the transverse bands, less distinctly and vividly margined with 
vermilion; but this may well vary in different examples, and the patch around the spinners has its fore part 
composed of three triangular patches meeting in the broad longitudinal dark band of the underside, which, 
in the example described, is very indistinct. 
The female has the abdominal markings much more vivid and distinct. The cephalothorax, falces, maxilla, 
labium, and sternum are yellow-brown. The legs yellow; the femora of the first pair with dark brown 
along the inner side, and those of the second pair with a well-defined dark elongate patch in front of the 
anterior half. The armature of the legs as in G. mivtus, 9. The genital aperture much resembles that 
of G. mixtus, but is characteristically distinct. | 
Hab. Guatemata, Chiacam (2 ), Menché (Rio Usumacinta) (¢ & 2) (Sarg). 
Gelanor distinctus, sp. n. 
Adult female, length 23 lines. 
This species, while bearing close resemblance in general form and markings on the abdomen, differs from all 
others known to me by the broad, central, longitudinal, tapering, distinctly defined, deep yellow-brown 
band on the cephalothorax. This band (on a pale yellow ground-colour) embraces the ocular area, and 
extends to the thoracic indentation (with somewhat irregularly dentated margins) in a more or less obtuse 
point, whence it again enlarges and continues to the posterior margin. On the sides of the thorax, and 
also on its margin near the junction of the caput and thorax, are two rather dark yellow-brown spots or 
markings.
