large, and around the external orifice of each are clustered 
several hundred round spinnerets and a few smaller tubular 
spinnerets. ‘The ventral surface of the abdomen is divided 
into segments by transverse furrows ond the posterior part is 
thickly set with round spinnerets. The anal plates are small, 
the postero-lateral side is convex and as long as the antero- 
lateral. Around the lateral margin there is ‘a row of minute 
hairs set far apart. ‘The dorsal derm is thickly set with 
small tubular glands.

long, sides not contiguous. The dorsum is creamy white, 
spotted with a number of small, irregular, dark olive- green 
spots, and with four irregular longitudinal furrows formed by 
a number of gland-pits. The derm is not very hard and is 
wrinkled and pitted by gland-pits. Beneath it is concave, 
light yellow, and with two prominent chalky lines on each 
side. Boiled in asolution of KOH it colours the liquid light 
brown. The derm becomes soft and transparent, but shows 
a number of small, dark, subcircular spots, 
Antenne variable, usually of eight joints, although some- 
times but seven joints are present. Length about *500 millim. 
All joints except 3 and 4 bear hairs. Fue nae formula :

joints: (1) 76, (2) 76, (3) 89, (4) 55, (5) 55, (6) 35, (7) 35, 
(8) 57. Legs ae coxa as al hairs and about 
four short spines; trochanter with two short spines and one 
long apical hair; tibia longer than tarsus. ‘arsal digitules 
long, slender, with expanded ends; digitules of claw large 
and thick, ends flattened and expanded. All the digitules 
extend far beyond the tip of claw. Length of joints of first 
pair of legs: coxa 186, femur with trochanter 26/7, tibia 191, 
tarsus and claw 142. Rostrum well developed, situated 
between the first pair of legs. Mentum large, with eight 
hairs near the tip. Rostral loop short. Spiracles large, with 
the exterior orifice greatly expanded and flattened. Many 
small round spinnerets are grouped about the spiracles, 
Anal ring apparently with eight hairs, one being found with 
nine hairs. Anal plates small, triangular, with the antero- 
lateral side longer than the postero- lateral. There is a double 
row of short hairs around the lateral margin of the body. 
‘Lhe stigmatal areas are characterized by groups of three 
large blunt spines, one of which is longer than the others,
