Two New Chaetognaths — AlvARINO

It appears that S. euneritica n. sp. is closely 
related to S. setosa Muller and S. friderici Ritter - 
Zahony, but there are several points of difference 
as shown in Table 4 and Figure 10. 
DISTRIBUTION: In the collections studied, 
CalCOFI cruises 5405 and 5804, it occurred 
close to shore from Cape Mendocino to Punta 
Eugenia in Baja California. Dr. Fager of the 
Scripps Institution collected some specimens 
using a hand-operated dredge net, when diving 
off the Tijuana River mouth (June, 1958) at 
a 50 -ft. depth and also south of Scripps Pier 
(August, 1958) at 20- and 26-ft. depths. 
Bieri (1957 and 1959) recorded this species 
as S. friderici ? in the same area along the coasts 
of North America extending south to the waters 
of Peru and Chile.
