878 e. etueridge, jun., on a lower-carboniferous decapod. 



Discussion. 



Mr. H. "Woodward expressed his gratification at the discovery of 

 this interesting Crustacean by Mr. Ethcridge, but could not feel 

 sure that it was a new species, although it may be so, as it occurs 

 so much lower down than any of those hitherto found. The most 

 interesting point in this specimen is the exposure of the gills by the 

 removal of the carapaoo, showing clearly its affinity to the highest 

 forms of Crustacea, in which the respiratory organs are entirely re- 

 moved from the feet and enclosed in special cavities.
