ADiEUM AREOLATUM, Sp. n. 



(S . Colour yellowish brown, generally obscured by the mud or 

 mould adhering to the granules. Dorsal scute with anterior 

 border convexly rounded and thickly beset with cylindrical 

 papUlfe ; ocular tubercle thickly granular, convexly rounded on 

 the summit ; behind the tubercle are two parallel rows of tubercles 

 extending to the posterior border of the scute and forming seg- 

 mental excrescences ; midway between these and the lateral 

 border is another irregular band of graniiles extending from the 

 antero-lateral angle ; there are also narrow transverse rows of 

 granules extending across the scute from side to side and passing 

 between the submedian granular excrescences ; the interspaces 

 between and defined by the bands of gTanules form subquadi-ate 

 smooth depressed areas. The posterior border of the scute and of 

 the three following tergites with a row of papilliform tubercles ; 

 the rest of the tergal plates thickly granular. Sterna granular 

 anteriorly. Goxce thickly granularly papillate. Genital sternum 

 with seven long hair-tipped papillae. Sternum of cephalothorax, 

 the adjacent area of the 3rd coxa and the maxillary process of 

 the 2ncl coxa forming a smooth and shining depression flanked on 

 each side by the papillse arising from the coxse. 



Mandibles with basal segment granularly tubercular above, with 

 one or two longer papillae distaUy ; second also with some sharp 

 tubercles in front. Palpi thicker than the legs, thickly granular ; 

 the femur at the base on the inner side with four strong spines 

 and one more distal, and beneath with one smaller and three 

 strong spines, and one strong spine on the inner side inferiorly ; 

 tibia, patella, and tarsus subequal in length ; the tibia without 

 distinct and lai-ge paired spines beneath ; tarsus with three pairs 

 of longer spines in addition to the tubercles ; claw short. 



Legs tubercular and granular, unspined, even the femur of the 

 1st hardly spined below ; some longiBh cylindrical papillse on the 

 outer side of the 2nd and 4th coxse ; tarsal segments 4, 11, 4, 4, 



$ . Differs from c? in that the papillse on the anterior border 

 of the carapace are shorter and form a median angular projection ;
