Alcock divides the family into two groups, assigning to Glypho- 

 crangon the species which have the eyes large and deeply pigmented 

 (purple in spirit), and which have eleven branchiae on either side, 

 and to a sub-genus Plastocrangon those in which the eyes are small 

 and unpigmented (pale yellow in spirit), and which have only nine 

 branchiae on either side, there being no arthrobranchiae pertaining to 

 the first and second peraeopods.

The establishment of Rliachocaris as a separate genus was due to 

 errors in the original account of Glyphocrangon. According to Bate 

 there are six pleuro-branchiae, belonging respectively to the third 

 maxillipeds, and each of the five peraeopods, and four arthro-branchige, 

 belonging to the third maxillipeds and each of the first three perteo- 

 pods. Professor Smith, on the other hand, affirms that there are 

 only five pleuro-branchiaB, one for each of the five peraeopods, and 

 six arthro-branchiaa, two on the third maxillipeds and one on each of
