ai-i'anged in 8 scries. Segments, 42-51. Sides of first segment striate. 

 Other segments deeply striate ; above nnmerous fine striae, which 

 have a number of short branches. Last segment produced into a 

 moderate spine, which projects beyond the anal valves, not pilose ; 

 anal valves not marginate, very sparsely pilose ; anal scale obtusely 

 rounded, rather small, pilose. Repugnatorial pore moderate, touch- 

 ing llie transverse suture, whicli is sharply sinuate. Pairs of feet, 66, 

 equaling width of body, rather slender, sparsely pilose. Male : Man- 

 dibulary stipes strongly produced beneath. First pair of feet large, 

 uncinate, numerous tubercles on the inner surface, pilose. Coxa? of 

 the second pair as in J. impressus. Genitalia about half concealed, 

 composed of three parts ; anterior plate round, the end strongly cla- 

 vate, pilose ; the middle plale rounded, curving up in front of ante- 

 rior and then backwards between it, where it expands into an elon- 

 gate, wavy plate ; on the inner side it is divided into three lobes or 

 spines, the anterior large and placed at the beginning of the expan- 

 sion, the second small and placed near the end, which is somewhat 

 serrated, a lanceolate spine springing from the base ; posterior plate 

 whip-like, curving upw^ards and inwards until they meet, and then 

 outwards. Flagellum not detected. Length of body, 30 mm., width, 

 2 mm.
