. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. BRUES: NEW SPECIES OF PERIPATUS. 311 lozenge-shaped pattern exhibited by some of the related species. On the ventral side the color is much lighter and quite distinctly purplish pink. The legs are intermediate in color between the upper and under sides of the body. Above they are lighter than the dorsal surface of the body, but much darker than their undersides which are in turn very decidedly darker than the underside of the body. Integument. The dorsal folds are sharply defined and the transverse grooves that separate them are deeply and clearly impressed. Between the furrows, the surface of each fold is regularly but not very strongly convex. Along the median line the number of folds is very uniform, twelve to each body segment, but laterally, particularly halfway to the base of the legs, many of the grooves coalesce. Near the middle body segments, there are on the average about two cases of coalescence to a segment, so that the folds are quite appreciably wider on the half of each side of the body which is next to the insertion of the legs. The dorsal median hyaline line is sharply defined, but is very much more distinct upon every second transverse fold, the alter- nating folds having only a very slight indication of it, either by reflected or by transmitted light. The hyaline organs (organes clairs) are not at all, or very feebly defined. The primary papillae are confined almost entirely to the ridges of the folds, although they do not form a straight line except in very rare cases. Usually they form an irregular line which is quite clearly distinguishable from the smaller papillae along the slopes of the fold, but exceptionally, some of the larger papillae descend a considerable distance from the ridges. The slopes of the folds are furnished with the smaller papillae, many of which ascend on to the ridges between the largest ones. The large, medium sized and small papillae intergrade
