Size: 3-54 mm.; anterior division (1-56 + 0-99) = 2-55 mm.; urosome 0-99 mm. Giesbrecht's specimens measured 2-85—2*95 mm. Near the lateral margin of the last thoracic somite is found, dorsally, a membranous fringe bearing short hairs; it is not equally prominent in all specimens, but generally more so than shown in fig. 13 a. The abdominal somite I c\i II has, dorsally, a characteristic process, and, on each side of the vulva lamelli-form processes more developed, on the right side. One of the 6 apical setae of the maxillae shows the structure characteristic of Pareuchcete with several short teeth and a few larger branches. The number of glandular pores in the legs scarcely Text-fig. 57. Euchcetehebes Gbt. differs from those of E. norv., except by the absence of any pore at the base of Se 1 Re III. Yd1 (St. V). Pes v The epistoma and the outer surface of the labrum are in main features like X 39- those of E. norv. The oral surface has the two first groups placed rather longitudinally, and the three following ones fairly well separated. The area in front of the lamina labialis is, as shown in fig. 13 b, rather characteristic, especially by the lateral group of hairs, which is a longitudinal ser
