Sagitta bipunctata Quoy et Gaimard = S. californica Michael 
S. bipunctata Michael, 1911 
S. californica, Bieri, 1957 
Bieri (1957) presents arguments supporting the change of the name of the species referred 
to by several workers as 5. bipunctata to 5. californica. Until this point is satisfactorily settled, 
I prefer to use the older name, S. bipunctata; but also to record that here, these two terms refer 
to the same single species. 
Body firm, moderately opaque. Tail segment 21-28 per cent of total body length; hooks 
5-10; anterior teeth 4-7; posterior teeth 8-14. Anterior fins start at posterior end of ventral 
ganglion. Posterior fins do not reach seminal vesicles; wider and slightly longer than anterior 
fins, widest behind tail-septum. Caudal fin joins seminal vesicles. Collarette present. No 
intestinal diverticula.
