Parada, s.vv. Caeneus 1, Hippea; Hyginus, Fabulae14. For Ischys as brother, see also Apollodorus, 3.10.3. Apollodorus, 1.9.16 lists "Caeneus, son of Coronus", as one of the Argonauts, which—under the assumption that this is the same Coronus, that this is not a mixup of the two names, and does not represents a separate tradition in which Caeneus was an Argonaut—would make this Argonaut Caeneus a grandson of Caeneus, see Parada, s.v. Coronus 1.
