Erroneous spelling in a Czech magazine, in which it is translated as "píšťaly s měchem" [pipes with [a] sack; ws], stating that "it is perhaps the oldest surviving precise description of this musical instrument", referring to the imperial Roman biographer Gaius Suetonius Tranquillus (ca. 70-ca. 135 AD) as its source; NB: The spelling utrikularis is also used by Juan Mari Beltran Argiñena in his article »Erromanizazio garaiko inguru honetako balizko hotsa« [Possible sounds of this region during the Romanisation period] in the Basque magazine Soinuberri 12 (2020), p.113-132.
