South African Crustacea. 239' 



All these authors call attention to the beaded ridge on the cara- 

 pace which iu this species runs more or less parallel to each 

 postero-lateral border. Dr. de Man suggests that it may be a 

 synonym of Pilumnoplax sulcatifrons, Stimpson, 1858, and 

 Alcock makes the same suggestion in regard to PseudorJiombita 

 sulcatifrons, var. australiensis, Miers, 1884 Targioni Tozzetti, 

 when re-discussing Stimpson's species in 1877, says that Stimpson 

 assigns to the male a length of mill. 32'5, and a breadth of mill. 

 41, whereas Stimpson's actual statement is " Carapacis long, 

 O325 ; lat. 0'41 poll." These measurements are not much in 

 excess of our specimen, which has length of carapace 6'5 mm., 

 greatest breadth 8 mm. All but one of the ambulatory limbs 



were missing.
