The outer surl'aee is worn aliove. but the lower part is eaneellated b'ke the .sputum. The longitudinal suleus is closed by infolding of its sides. The spur is long, rounded at the end, and situated at less than its own width from the .scutal margin. On both sides the liasal margins .slope steeply to the .spur. The interior is yellow, with a long purple spot in the middle. Artieular ridge .short, subereet and ihiii. ,\ low, Hat, gently areuate rib runs from the spur to the apical beak, in which a tine cavity l>enetrates from the apex of the |iuri)le spot. The depressor crests are few and not very strong. Ba-sal length of the walls 70 mm., height 75 nnn. Length of the scutum 31 mm., breadth 13.,5 mm. Length of tergum with s|inr '.VI nun., lireadth 12 mm. The mandible (fig. L'. n, left side) has four small teeth, the last adjacent to .several low obtuse at the lower end. The end of the maxilla is sigmoid, the upper half excavated, the lower convex. It is armed with numerous stout and slender spines (fig. 2, c. right side). The first pair of cirri has wiile rami like moth antenna', the posterior one three-fourths as long as the anterior, with greatly jiroirnding segments, about 21' in number. The segments of tlu' anterior ramus are less ]m)truding 'i^£:.
