collector and date of collection are unknown. 
Solem (1985) commented that the species 
should never have been described because "The 
available material is so badly worn that 
reference to a genus with any degree of 
certainty is impossible. ... The large number of 
whorls, reflected lip, lack of body whorl 
inflation and lack of body whorl descension also 
suggest it is not a Kimboraga."
