Eusicyonia and Oijyridcs are offered respectively in exchange. 

 Incidentally a parasitic isopod is named Heniiartlirus nemaiocarcini 

 and the amphipod Plaiyischnopus mirahilis is added to the South 

 African fauna.

 The genera included in this family, according to Alcock, 

 are Pomatocheles , Miers, 1879, Pylochclcs, A. Milne-Edwards, 

 1880, Mixtopagurus, A. Milne-Edwards, 1880, Cheiroplatca, 

 Bate, 1888, and Parapylochclcs, Alcock, 1901. The proximity 

 of Pomatocheles to Pylochelcs was noticed by A. Milne- 

 Edwards and Bouvier in 1893, and in 1913 the species 

 Pomatocheles jeffreysii, Miers, is transferred by Balss to 

 Mixtopagurus. But clearly the generic name given by 

 Miers has the precedence, and the union of the two genera 

 requires that the Mixtopagurus paradoxus of A. Milne- 

 Edwards and Henderson's Pylochelcs spinosus should be 

 renamed as species of Pomatocheles. There is a difficulty 

 in x-egard to Mixtopagurus gilli, Benedict, 1901, that it has 

 a very unsymmetrical telson, which would seem to exclude 

 it from this family altogether. That the family should be 

 named Pomatochelidac after its premier genus, as Alcock 

 suggested in 1901, is to my mind obvious, but quot homines, 

 tot sententiae.
