The Dragon rocket used a large 0.56m diameter lower stage, like Centaure's Venus but bigger, to boost the Belier upper stage. The lower stage uses the Stromboli motor, and is called Dauphin when flown by itself. Eridan has a Stromboli stage 1 and Stromboli stage 2.

The two-stage Eridan was mostly used for experimental flights. The typed CNES record ends in Oct 1971, but M. Latour has added in manuscript four launches (one Dauphin and three Eridan) made in 1978-79 and denoted `qualification CSG' - presumably range tests prior to the first Ariane flight.

The Terre Adelie flights of Jan 1967 are recorded in the CNES list as: D24, D27, D26, D27. I believe that one of the D27's should be D25.
