Fig. 2 in Observations ofApparent LoricaVariability inSalpingacantha (Ciliophora: Tintinnida) in the Northern Pacific and Arctic Oceans
Fig. 2. Varieties of Salpingacantha from a 2016 sample in the Chuk- chi Sea (2016 St 29). In the sample no typical Salpingella acuminata were found.

Note that form "c" if rotated 45° could easily be mistaken for Salpingella acuminata.
