We present four cases of rare developmental anomalies in the smooth snake Coronella austriaca Laurenti, 1768 from western Poland. These include brachycephaly, lordosis, a supernumerary row of ‘ventral’ scales, and the third reported case of dicephalism in snakes from Poland. All the cases are supported by X-ray radiography. One of the possible explanations for these anomalies is a low genetic variation in populations from western Poland.
