The following notes may be added to the original description: eyes about 
seven or eight diameters apart, being situated on a more or less distinct 
ocular tubercle which is quite twice as broad as long and almost subdivided 
by a median depression into two tubercles : this ocular region proj ects forwards 
a little in front of the more lateral portions of the head-plate but is not nearly 
so forwardly produced as in the males of Hexisopus, where the eyes are much 
nearer together according to Purcell’s accounts. Inner surface of chelicerae 
without feathered bristles, and with no row of spines nor even stiff bristles on 
the upper jaw: stridulatory area rather large, with a reticulation of furrows.

above, b, Head-plate seen from the side, c, Third leg viewed from its upper side 
(this leg is considerably twisted), d, Distal segments of same, more enlarged, in 
ventral view, e, Second leg and / fourth leg. 
Coxa of palps with a fairly prominent maxillary lobe : this is not so long as 
that of Solpuga, but is longer and more conspicuous than in Daesia. The 
palp has very stout spines on its surfaces, four on the tarsus, about 11 on the 
tibia, and several on the patella. Claws of second and third legs of two seg- 
ments, but the basal segment is almost obsolete, being about one-twelfth as 
long as the distal segment: according to Dr Purcell, this character may vary 
considerably amongst the individuals of the same species {Hexisopus lanatus). 
The anal slit is large, and the whole segment moderately large. A small 
median spiracle on the fourth abdominal sternite, which is also traceable in
