Each palp seems to be quite perfect and there is no distinct evidence of fusion of any two segments. This species is much larger than A. tetrapora and is characterized by (i) the long, tapering proboscis, (2) the relatively short palp (in A. tetrapora the palp is longer than the proboscis), (3) the ver}' large spine on the propodus, and (4) the blunt antero-lateral cephaHc lobes.

There can be no doubt that these tvvo specimens belong to A. spinosa although they are more compactly built, with much smaller non-recurved 'tubercular processes' on each lateral process, than in the holotype. Also the fine, silky hairs on body and legs are very sparse. One of the most outstanding charac- teristics of the species, namely the varia- tion in the terminal segments of the walking legs, has not been adequately described by Hodgson (1907, p. 50). In all specimens examined the two anterior pairs of legs each have the propodus rela- tively short and stout, with numerous spines on the ventral margin arranged in the manner represented in Fig. 53 a. The propodus of the third or fourth leg, on the other hand, is relatively slender with 6-7 small spines on the proximal half of the ventral margin and none on the distal
