MARINEi GAMMARIDEAN AMPHIPODA 481 



Supplement 



Recent studies by the writer in Hawaii, New Zealand, and Australia 

 suggest the following changes and additions to the classificatory 

 scheme of Gammaridea. 



The Eusiridae and Calliopiidae must be amalgamated. 



The Aoridae must be amalgamated with the Isaeidae; most genera 

 of the Corophiidae should also be placed in the greater Isaeidae but 

 Corophium and Paracorophium might be retained within a subfamily. 



Ceina is to be removed from the Phliantidae to form the type of a 

 new family with close afhnities to the Hyalidae; the family will be 

 characterized by the loss of rami on uropod 3 and the rough skin 

 texture; it has affinities with various freshwater chiltonias that may 

 require removal from the Hyalellidae to form a group distinct from 

 the American hyalellas. 



Biancolina is to be removed from the Eophliantidae to form the 

 type of a new family. The biramous uropod 3 of Biancolina is one 

 mark of its distinction from Eophliantidae. Atnphitholina should also 

 be removed from Eophliantidae and returned to the Ampithoidae as 

 type of a new subfamily. 



The freshwater genus Paracalliope is added to the list of marine 

 genera as one of its species, Oedicerus novizealandiae Dana (1853), is 

 definitely intertidal in New Zealand. That species is not a member 

 of Carolohatea as heretofore considered (Chilton, 1909). Stebbing 

 (1906) had already suggested Dana's species to be identical with P. 

 Jliwiatilis (Thomson) but the two are definitely distinct. 



Paracalliope Stebbing 



Paracalliope Stebbing, 1899d; 1906. 



Type-species: Calliope fluviatilis Thomson, 1879 (original desig- 

 nation) . 



Eusirid-calliopiid with incii)ient characters of Oedicerotidae, es- 

 pecially in the disproportionately elongate pereopod 5 with elongate, 

 terminally setose dactyl and elongate uropod 3. 



Eyes paired, discontiguous; accessory flagellum vestigial; inner 

 plates of maxillae 1-2 heavily setose medially, maxilla 2 with addi- 

 tional submarginal row of medial setae; female gnathopods weak, 

 those of male stout, with erect lobes on fifth articles, hands twisted 

 mediad, ])alms bearing large spines; coxa 4 weakly or not postero- 

 dorsally excavate; telson ovoid, thin, uncleft; urosomites 2-3 coalesced. 

 Species: 5 (2 undescribed). New Zealand, AustraHa, Philippine 

 Islands, India, marine littoral, brackish and freshwaters.
