1. Tygarrup monoporus sp. nov. Body length about 17mm. Paris of legs are 41. General colour yellow but head and prefensors deep brown. The ratio of length to width of cephalic plate is 6:5, and the posterior margin is shorter than the anterior. Frontal plate discretes. Areolate precrypeus is V-shaped and most narrowed on middle of it, which is no satae but each side with a long geminate satae. The wide non-areolate postcrypeus with about thirty median short satae, but posterior third without. Median piece of labrun cuneiform, lateral lobes with many cilia long and short, but without longitudinal sutures. Mandible with five pectinate lobes, first with 6, second 9, third 8, fourth 6, fifth 2-3 (incomplete)teeth. Coxopleura of first maxillae with clearly median suture, telopodite with2 setae and coxal process with several setae. Syncoxite of second maxillae areolate, completely adhered. Telopodite of it with 15-18 satae on distal article, and claw is small. Anterior margin of syncoxite of toxicognath with two teeth at middle, prefemur with a tooth, femur and tibia each with a small process, tarsuswithout. Ventral stripe presents from the first to thirteenth sternites. Anal leg with no claw, and coxal pore only large one. Anal pore presents. Holotype: One female from Manazuru, Kanagawa Pref., Sept. 22, 1957 collected by the author. 2. Mecistocephalus (Mecistocephalus) manazurensis sp. nov. Body length 22-25mm. Pairs of legs 45. General colour yellowish brown with dark spot except last segment, therefore it seems two longitudinal dark stripes. Head is deep brown but toxocognath segment is lighter colour than that of head. The ratio of length to width of cephalic plate is 3:2, trapezoid, and anterior margin of it is 1.6 times the posterior. Frontal portion discrete. Areolate precrypeus with symmetrical three setae on each side, but postcrypeus non-areolate and without setae. Lateral plate with several setae on posterior half. Mandible with four pectinate lobes, first 7, second 8-10, third 7-9, fouth 5-7 teeth and non-pectinate one. Median piece of labrum wedge-shaped and no cilia on lateral piece. Coxite of the first maxillae with 1-2, telopodite with 1, coxal process with 4 setae. Syncoxite of thesecond maxillae well adhered, several setae with each side and areolate on middle. Femur of telopodite with one, tibia several, tarsus about thirteen setae, and claw is sharp. Prefemur stout, with a large tooth, tibia with one tooth, but femur with a small precess, Ventral stripe presents, not branched. Dorsal setae are long and short, but ventral are short relatively. Last ventral plate constricted and divided into two parts, anterior part with long setae but shorter posterior is covered by numerous finespun hairs. Coxal pores of anal leg are 13-14. Large anal pore presents. Holotype: One female, Manazuru, Kanagawa Pref., Sept.20, 1957 collected by the author. Allotype: One male, data same as above.
