We show that the symmetric quark model calculation of charmed baryon pair creation in e + e − -annihilation has an incorrect threshold structure. The cc̄-pair creation model possesses the correct s-wave threshold behaviour, if the cc̄-pair and diquark pair are created in orbital s-waves. We show that the two models become identical for a specific orbital configuration and discuss implications for the relative production rates of Λ c Λ c :Σ c Σ c :Σ c Σ c ∗ +Σ c ∗ Σ c :Σ c ∗ c ∗ .
