| Summary: | This second report of the Comissió de Cetologia of the Institució Catalana d'Història Natural includes 34 records of Cetaceans in the Mediterranean area between the French border in the North and Valencia in the South, and also from the Balearic Islands. From other coasts of the Spanish state there are few citations as there are no periodical surveys. We are trying to create local groups all along the Spanish state coasts to avoid this lack of information. The existence of six strandings of striped dolphin (Stenella coeruleoalba) obliges to discuss its incidence in the past and in the present. It seems that now the striped dolphin is becoming a very common species in the Catalan Mediterranean coast. The situation of the common dolphin (Delphinus delphis) would be opposed. For the remaining species the situation is the same that CASINOS & VERICAD (1976) evidenced. In each case the locality, date, morphological and biological data, preserved material, references and observer are noted. A short description of the specimens collected is following: Balaenoptera physalus 1. Stranded dead specimen on Ca16 des Mort (Formentera Island). Physeter macrocephalus 2.
