Thanks JAHdeB for his present of two volumes [Description des Entomostracés fossiles des terrains tertiaires de la France et de la Belgique (1852) and "Les Crustacés fossiles du Limbourg" (1854)]. CD was interested in the remarks on geographical distribution of the Entomostraca.
CD’s second volume for the Ray Society [Living Cirripedia] is finished but not yet published.
