the intermediate stages between them. Those belonging to the 

 first type show in addition a well-marked lateral stiipe of a 

 greenish-blue colour. The antennae are also of a greenish-blue, 

 thus differing from those of Prof. Bouvier's specimens which he 

 describes as always being black. Four of the animals are 

 very dark in colour, one being practically black, but all have a 

 brownish-green tinge ; the ventral surface is lighter, but even 

 then darker than the backs of the other specimens. The darkest 

 specimen, which is a male, diifers from all the others in having 

 the crui-al papillte black instead of white. All the animals show 

 a patch of green pigment on the inner side of each leg which is 

 extended on to the ventral surface of the body. In most cases 

 the ventral and pre- ventral organs are not well-marked, but some 

 of the smaller specimens show the ventral organs distinctly. 

 The two light coloured papillpe described by Prof. Bouvier a.s 

 situated between each pair of legs are not apparent in these 

 specimens. 



The coloration of these Peripatus agrees faii"ly closely with 

 that of Peripatoides orientalis *, except that the dark variety is 

 by far the most common in the last-named species (77| per cent, 

 according to Steel t), whereas in P. tooochoardi they are in the 

 minorit}^, as far as our present material goes. 



With regard to the exteimal features, these specimens of 

 P. ivoodtoardi agree with those described by Prof, Bouvier J in 

 every respect except for the number of crural papillfe in the male. 

 These are very prominent and capable of reti-action within the 

 leg, and he describes them as present on all the legs with 

 the possible exception of the 15th and 16th, that is the last two 

 pairs, while he found coxal glands in all the legs except possibly 

 the 15th pair. 



T have examined all the males in my material, and although 

 the papillfe show extremely clearly in most cases, I can find no 

 traces of them on the 4th or 5th legs ; they appear to be entirely 

 absent from these legs, as Avell as from the 15th ; the last pair 

 of legs may show a small papilla. In the male that I dissected 

 the coxal glands showed very clearly in the other legs, but no 

 trace appeared in the 4th, 5th, or 15th pairs. The absence of 

 these glands in the 4th and 5th paii-s of legs seems to be correlated 

 with the great development of their nephridia,, which open by a 

 urinary papilla on the proximal of the three spinous pads of the 

 foot. 



As described by Prof. Bouvier, the first pair of crural glands 

 are extremely long and lie in the lateral sinus with the nephridia ; 

 the last pair are elongated and iridescent and lie in the lateral 

 sinus or in the general cavity of the body, while the remaining
