The need for large samples is illustrated by the very low prevalence of at least four haplosporidians: Bonamia perspora in only 31 of 2,144 (1.4%) crested oysters Ostreola
equestris (Carnegie et al.

The other is the Pacific coast's Olympia oyster, Ostreola
conchaphila, which ranges from Alaska to Baja California (Fig.
Analyses of DNA sequences indicate that several genera proposed by Harry (1985), which are often monospecific, are embedded in Ostrea and should be reverted to Ostrea, including Cryptostrea, Myrakeena, Ostreola
, Teskeyostrea, and Undulostrea (Lapegue et al.
Three other genera, Myrakeena, Ostreola
, and Cryptoostrea, established by Harry (1985) based on shell morphology, are also not supported by DNA sequence data (Salvi et al.

I also agree with Baker (1995) that Ostrea lurida should be retained as the scientific name for the Olympia oyster for several other reasons, namely: (1) Harry's determination was based on shell and anatomical characteristics, not molecular evidence; (2) most of the scientific papers and fishery publications about the species refer to it as Ostrea lurida, and very few as Ostrea (Ostreola
) conchaphila; and, following from this usage, (3) conformity with provisions of the International Code of Zoological Nomenclature regarding suppression of unused senior synonyms dictates that Ostrea lurida should be used.
A separate issue is Harry's (1985) revival of Ostreola
Monterosato 1884 (type species Ostrea stentina [Payraudeau, 1826]), which he also extended to include O.
