Type material. Holotype: NHMW 84194, height 11.7 mm. Type locality. Station 54, 24°48'N , 35°25'E , Central Red Sea, 535 m. Original description. Das Gewinde dieser mit Nassa munda m. verwandten Form besteht aus 8 1/2 Umgaengen und ist oben stufig abgesetzt. Die Querwuelste stehen bedeutend enger als bei jener Art, so dass auf der letzten Windung etwa 35 abzuzaehlen sind. Von einer Baenderung nur ganz geringe Spuren sichtbar. Aussenrand der Muendung mehrfach und unregelmaessig gezaehnt . Hoehe der Schale 11 1/2 , Breite 6 1/4 mm; Muendung 6 mm hoch und 3 1/2 mm breit. - Ein einziges Exemplar von Station 54 (535 m). Figure 14. Nassa sporadica Sturany, 1900, Station 54 (Central Red Sea). A-C , E. Holotype, NHMW 84194: front ( A ), right side ( B ), back ( C ), protoconch ( E ). D . Original figure by Sturany (1903) . F . Original holotype label. Scale bars: A-C : 2 mm, E : 0.2 mm. Translation. The spire of this species is related to the one of Nassa munda and consists of 8.5 whorls and is scalariform on top. The axial ribs are significantly closer compared to the mentioned species, so on the last whorl 35 can be counted. Only very small traces of colour bands are visible. Lip with numerous and irregular teeth. Shell height 11.5, width 6.25 mm; mouth 6 mm high and 3.5 mm wide. One specimen from station 54 (535 m). Comments. Nassa sporadica was regarded as nomen dubium and possible synonym of Nassarius (Zeuxis) crebricostatus (Schepman, 1911) by Cernohorsky (1984 : 160). For further comments on validity of sporadica see under Nassa munda .
