Etymology 'Caput' indicates the head, and 'esocis' is a genitive coming from Esox, Latin for the pike fish (esox, esocis, m), a name used as early as Pliny. Thus Saint-Joseph was indicating a 'pike-head' shape of the worm head. This is not a particularly obvious likeness from the fig. 58 head figure, but the head had large dorsal eyes, narrows and is blunt at the end. Saint-Joseph (1894: 53) explicitly compared the worm head to that of a pike when he wrote: "La tête très caractéristique (fig. 58) a la forme d'un museau de brochet un peu aplati en avant avec deux gros yeux noirs placés à la partie postérieure sur les ganglions cérébraux." [The very characteristic head (fig. 58) has the shape of a pike muzzle a little flattened forward with two large black eyes placed at the side posterior on the cerebral ganglia.] [details]

Etymology 'Caput' indicates the head, and 'esocis' is a genitive coming from Esox, Latin for the pike fish (esox, esocis, m), a name used as early as Pliny. Thus Saint-Joseph was indicating a 'pike-head' shape of the worm head. This is not a particularly obvious likeness from the fig. 58 head figure, but the head had large dorsal eyes, narrows and is blunt at the end. Saint-Joseph (1894: 53) explicitly compared the worm head to that of a pike when he wrote: "La tête très caractéristique (fig. 58) a la forme d'un museau de brochet un peu aplati en avant avec deux gros yeux noirs placés à la partie postérieure sur les ganglions cérébraux." [The very characteristic head (fig. 58) has the shape of a pike muzzle a little flattened forward with two large black eyes placed at the side posterior on the cerebral ganglia.] [details]

Spelling Saint-Joseph (1894) presented the species name as two words, repeating this within the description, thus as 'caput esocis'. However, this is not permitted by the ICZN Code, and the two words must be combined, without a hyphen [details]

Type locality Dinard coast, NE Brittany, France, in trawls (no further specification of location with the description text) [details]

Type specimen Woodham & Chambers (1994:311) found a syntype and commented: "In European waters, Caulleriella caputesocis (de Saint-Joseph, 1894) is the only other bi-tentaculate cirratulid reported to have eyes and to possess unidentate spines in both rami. As the precise identity of this species is unclear, and the original figures uninformative, a syntype of Heterocirrus caputesocis (MNHN A181) was examined. It is in poor condition and in three pieces, measuring 15 mm for 75 segments in total. The eyes figured and described by Saint-Joseph are not visible. The specimen does not closely resemble the original figures, but unidentate spines are present in the posterior region and these do not form complete rings around the body. The overall shape of the body and of the head clearly separates C.gibber from this specimen, which cannot be assigned to any known species from the UK. " [details]
