BKACHYURA. KATHBUN. 151 



The sternal sulci end not far apart on a line with the 

 intervals between the cheliped and the next leg. 



Relationships. This species lias much in common with 

 Drornidia spongiosa, Stimpson- 4 , which, according to the 

 author's figure, has no antero-lateral angle, but a regularly 

 rounded margin ; otherwise the features of the anterior and 

 lateral margins appear to be similar. In spongiosa the 

 legs of the last pair are broader, and both prehensile legs 

 are devoid of the supplementary spines characteristic of 

 insignis.

This species differs from Borradaile's description of 

 Cryptodromia in that the walking legs are not knobbed or 

 ridged and there is a thorn on the outer side of the dactylus 

 of the last leg. 



The following description is taken almost entirely from 

 manuscript prepared by Mr. A. R. McCulloch: 



"A series of eight specimens, 20-64 mm. wide, shows the 

 same variation as noted by Baker in the armature of the 

 antero-lateral borders of the carapace and the upper margin 

 of the hand.
