stripes above the legs will be almost entirely red, contrasting well 

 with the intervening series. Interesting variations of this pattern 

 arise by the partial filling in of the lozenges of the median series; 

 the red ma}'- be aggregated in a little patch on each side of the 

 nodose enlargement on the median dark line, or it may just fill 

 in the lateral apices of each lozenge. The most complicated pattern 

 arising from a secondary arrangement of (four-sided) diamonds 

 may be described as follows : Two lines intersecting in each 

 nodose enlargement of the median dark line cut off from a lozenge 

 a pair of small diamonds, one on each side of the median line 

 corresponding with the legs; and an anterior and posterior portion 

 which, with the posterior portion of the lozenge preceding, and 

 the anterior of the succeeding one, make up two of a single 

 median interrupted series of larger diamonds, each of which 

 corresponds with the interval between the legs^ : the former are 

 sometimes filled in with red; the latter jDartially. Sometimes 

 the dark boundaries disappear, leaving only the patches of red. 

 The light longitudinal stripe above the insertion of the legs is 

 usually very distinct, but sometimes there are only indications of 

 it, or it is a discontinuous series of orange or red patches above 

 the intervals between the successive legs of each side. Its light 

 tint may be due to the presence of light blue both in the ground 

 colour, and on the primary papillae with the exception of their 

 summits. 



I have seen onl}^ a very small series of the larger Victorian 

 Peripatus, but as far as it goes the following slight differences 

 attract my notice. The median dark longitudinal line is either 

 wanting or is not so marked a feature as in our variety; and the 

 unpigmented median groove is rather more conspicuous. The 

 line of demarcation between the median and each lateral series of 

 the mosaic is better defined; that between the lateral series and 

 the longitudinal stripe is not, I think, quite so definite. The 

 longitudinal stripe above the legs, except in specimens with a 

 very large amount of red, is not so clearly indicated as is usually 



* That is, the interval between two consecutive legs of the same side.
