Hi Norrie--the code in your sample is called Cypria ophtalmica (Jurine, 1820) Brady and Norman 1889. At least thats how I list them in my modern database. there are the usual issues about what exactly should be called C. ophtalmica versus other choices, but I for now put all of the choices in this name. It was in your K samples the things in the N sample are not codes or if they are they no longer look like codes. As to C. ophtalmica it is one of the unuusal continental forms that is truely nektic and tends to have a northern distribution. Of 69 listings in the database its mean tds is 200 m it minimum is 16 mg/L and max is 1450 mg/L, but it tends to like the dilute end with 57 of the 69 recorded occurrences being 300 mg/L or less. Hope this helps your cause.
