Set@.—The dorsal setal bundles began on 
the fifth segment; each bundle consisted 
of one hair- and one needle-seta. The 
hairs were fine, smooth, pointed, and 
about ‘16 mm. long, or nearly as long 
as the body of the animal was broad. 
The needles had a slight double curve 
(text-fig. 7), and were forked distally, 
the prong on the outer side of the curve 
being slightly shorter and much thinner 
than that on the inner side; the nodulus 
was situated at the junction of the distal 
a : and middle thirds, and there was a second
