Oblong-oval, moderately convex, granulate ; the granules 

 seriate along the posterior margin of each segment, and partly-

 narrow and very prominent. Eyes small, black. Segments of 

 the thorax slightly tending backward at their latero-posterior 

 angles. Segments of the abdomen very short, smooth on the 

 sides, and with the latero-posterior angles acute, directed back- 

 wards, terminal segment triangular, acute, concave above, 

 narrowed posteriorly, scarcely reaching beyond the latero- 

 posterior angles of the penultimate segment. Caudal appendages

 Porcellio obtusifrons, Haswell, MS. 



Body broad and convex. Head short, transverse ; lateral 

 frontal lobes rather prominent, but scarcely extending beyond 

 the antero-lateral angles of the first thoracic segment ; mesial 

 frontal lobe very low, much less prominent than the lateral lobes, 

 forming an obtuse angle. Segments of the thorax with their 

 postero-lateral angles slightly produced backwards. Abdominal 

 segments with their postero-lateral angles strongly produced and 

 acute. Last segment short, produced behind into a narrow 

 mesial sub-acute process, which, however, scarcely extends 

 beyond the postero-lateral angles of the penultimate segment. 

 Caudal appendages extending well beyond the apex of the 

 terminal segment ; inner ramus narrow, pointed ; outer ramus 

 nearly twice as long as the inner, lanceolate. Length nearly 

 \ in. ; breadth about \ in. Colour slate-grey, with lighter mark- 

 ings towards the middle of each segment.
