Remarks .—The most noteworthy character of the specimen described above is the 
presence of only eight segments in the palp, as compared with the nine that are present- 
in the other species of the genus. The condition of the palps in some specimens of 
C. lilliei, described below, suggests the possibility that the reduction may be the result 
of regeneration after injury, but the complete symmetry of the two palps in the present 
specimen is against this supposition. The relation of the species to Hodgson’s 
“ Notoencleis” has already been alluded to. Apart from the character of the palps, 
the species is sufficiently distinguished from all other species of the genus by the 
characters given in the key. 
The species is named in memory of Dr. E. A. Wilson, the chief of the scientific 
staff of the expedition.
