transverse band of these granules also lies on the branchial 

 region on either side in a line between the posterior teeth 

 of the antero-lateral borders, A similar band marks the 

 anterior cardiac region, and the inner halves of the supra- 

 orbital margins are likewise furnished with these granules. 

 A few of these crystalline granules also occur on the upper 

 aspect of the wrist and palm of both the larger and smaller 

 chclipeds. 



The posterior half of the carapace has a dense short furry 

 coating, as also have thorax, abdomen, chclipeds to bases of 

 fingers, and the exposed surfaces of the legs. 



The supra-orbital margin has a notch just internal to the 

 outer angle. The outer orbital angle is dentiform and 

 similar to the teeth of the antero-lateral border. Just below 

 the outer angle is an angular notch. The basal antennal 

 joint just reaches the front; the orbital hiatus is not closed. 



The elielipeds are unequal ; upper border of arm is serru- 

 late ; inner angle of wrist is sharp, its exposed surface 

 having a few sharp crystalline granules, as also has the outer 

 surface of the palm. Margins of legs are fringed with long 

 hairs. 



Only one male specimen was obtained, at Sta. 292, Persian 

 Gulf, 53 fathoms. Length of carapace 6 mm., the greatest 

 width 75 mm. A figure of this specimen will be given iu

This species was described by Anderson from a single 

 specimen (a female) caught oft' the west coast of Ceylon. 

 This season another female was caught at Sta. 323, west of 

 Cape Negrais, 463 fathoms, and also a male at Sta. 322, east 

 of South Andaman Island, 378 fathoms. 



Description of male. — It is smaller than any of the females 

 in the Museum collection. As in the female, a very promi- 

 nent and proeurved lateral epibranchial spine is present on 

 either side ; it is about the same size as the frontal prongs. 

 The three frontal spines are about the same length ; iu the 

 specimens available the central spine is in the male very
