BEACHYURA. RATHBDN. 129 



addition there are three spines in a triangle on the 

 epibranchial region and two on the hepatic region. There 

 are in all nine gastric spines, in transverse series: two on 

 each epigastric lobe, and on each protogastric lobe, and in 

 line with the latter, a small mesogastric spine. Frontal 

 marginal spines six, the middle pair largest, the outer pair 

 situated at the angle of the orbit; behind them there is a 

 row of four spines. There are two supraorbital spines 

 besides the three already mentioned ; suborbital spines five, 

 the inner one much the longest, the others diminishing in 

 size. Post-lateral regions rough with short spinules. A 

 row of tubercles above the posterior margin. 



Chelipeds unequal in all the specimens, but not much so ; 

 the armature is strong and similar. The spines of the legs 

 are slenderer. 



In the three small specimens handled the spines retain 

 about the same proportion to the size of the crab. In the 

 type figured (about natural size) by de Haan, loc. cit., 

 which is a female, not a male, as labelled, the spines of the 

 appendages and of the margin of the carapace maintain 

 about the same relative size as in the young, but the dorsal 

 spines are reduced in size and the hairs of the carapace 

 seem to have disappeared. Both chelte are spinous as in 

 the young. 



In Doflein's figure (loc. cit.) which is of a much larger 

 specimen, a male 15 cm. wide, all the spines are much 

 reduced, some of them to spinules ; the major cheliped has 

 increased enormously while the minor one has remained 

 stationary; the major chela is nearly smooth. 



This species had not before been taken outside of 

 Japanese waters.
