In my opinion Bathynomus should be given precedence over Palaega. To drop
the widely recognized name Bathynomus would create a lot oftrouble among non-

Palaega,asdefinedbythetypespeciesP.carteriWoodward, 1870,isunambiguously
distinct from Bathynomus. In all extant Bathynomus species the pleotelson posterior
margin is truncate or subtruncate and provided with a number of distinct widely
separated prominent spines. The pleotelson itself is always relatively short (about
0.67-0.86aslongaswide(Bruce, 1986)). InPalaegacarteritheposteriormarginofthe
pleotelsonissmoothlycurvedorroundedandisfinelyserratewithaprominentmedian
point;thepleotelsonisnearlyaslongaswide(ratio0.94,0.95(Woodward, 1870)).
Wieder & Feldmann (1989) made a fundamental error in assuming that because
Palaega goedertorum appeared indistinguishable from Bathynomus it followed that
Bathynomusand Palaegawere synonymous. Palaega, asconstituted by thecurrently
includedspecies,isnotavalidgenus.Wieder&Feldmann(1989)themselvesacknowl-
edgethatitisaformgenuswithrepresentativesfromseveralfamilies. Speciessuchas
P. lamnae Bowman, 1971 and P.pumila Gall & Grauvogel, 1971 are not congeneric
withthetypespeciesandcouldbelongtodifferentfamilies.
ThediagnosesprovidedbyWieder&Feldmannarenotcongruentwithcontempor-
arydiagnosesofextantisopodtaxaandcannotthereforebeappliedtoextantisopods.
Their diagnosis to the cirolanidae effectively diagnoses only the Flabellifera.
Similarly,theirdiagnosisforPalaegacouldbeappliedtoseveralfamilies.Thereislittle
utilityinsynonymising aprecisely defined genus with a name that approximates to a
groupoffamilies.
In summary, it is my opinion that Palaega carteri Woodward is not congeneric
with Bathynomus. Notwithstanding, some fossil isopods could well be species of
Bathynomus.Inordertomaintainstabilityintheuseo^BathynomusIstronglyurgethe
