If I am correct in regarding all the individuals in the collection, which present every 
grade of variation of abdominal configuration between the two extreme forms figured 
on the Plate, as belonging to one species, then they will all fall under Epeira arenata, 
Walck., as determined by McCook. These spiders also vary very much in the colour 
of the carapace and legs. ‘The lateral sclerites of the vulva, too, pass through all the 
gradations from circular to circular-triangular on each side of the basal portion. In 
the type (¢ ) of V. reticulata (O. P.-Cambr.) the spines on the apex of the spur on the 
inner upper side of tibia ii. are not both at the extreme tip, but one is below the 
other.

Type ¢, gynetype 9,in coll. Godman & Salvin. Total length, ¢ 3°75, 9 7-8 millim. 
Carapace dull yellow, variegated with brown spots. Abdomen with nine warts posteriorly, in three rows of 
three each, and with one lateral wart in addition between the former and the shoulder-wart on each side. 
Legs dull yellow; femora i. and ii. with two short black lines in front at the apex and a single, short, 
dorsal, apical, black line. Protarsi i. and ii. with a narrow, central, black line extending over the whole 
length. Femora i. and ii. without rows of spines in front. Scapus of the vulva on each side remote 
from the base. Tibia ii. of the male with the large central spur; the two spines at its apex being set in 
the same straight line transversely, with two spines only on the outer upper side in the apical half. 
Embolus of male palpus straight at apex and directed forward ; clavis with one tooth at its lower apical 
margin. 
Hab. Muxico, Teapa in Tabasco (H. H. Smith); Guatemata?, Vera Paz (Sarq) ; 
Costa Rica (Rogers); Panama, Bugaba (Champion '). 
The examples of this species before me vary very much in the configuration of the 
abdomen, from being almost circular to triangular, with quite sharp shoulder-points.
