celer Humbert & Saussure, 1870: 202-203 [Branchiostoma].

Carolina. Unspecified series.

Saussure & Humbert (1872) gave a more detailed redescription, implying that they had more than one specimen. The MHNG collection contains one specimen in alcohol under the name Branchiostoma celer and at least six specimens in alcohol under the name Rhysida celeris . A label in the first jar reads “ Branchiostoma celer Humb. & Sss. Caroline (Type) ” indicating that it is a syntype. A label in the second jar reads “ Rhysida celeris H. u. Sauss., Guatemala, Mr Oltramare” and despite a syntype label placed in the jar these are not part of the type series. There is a further syntype, labelled “leg. Alois v. Lederer,” in the NHMW (Inventory Number 1572, Acquisition Number 1866.I.334).
