Derivation of the name: From the Latin for dog (canis), an oblique reference to Sirius (hence dog−star) Passet.
Holotype: MGUH 28.886 View Materials . ( Fig. 3C); complete specimen preserved in dorsal view.
Type locality: Peary Land, central North Greenland, at the south−western end of the broad valley connecting J.P. Koch Fjord and Brainard Sund ( Fig. 1 View Fig ). Latitude 82 ° 47.6’ N, longitude 42 ° 13.7’ W, altitude of 450 m above sea level GoogleMaps .

Material.— The holotype and MGUH 28.880 View Materials – 28.885 View Materials , 28.887 View Materials – 28.899 View Materials .
Diagnosis.—Medium−sized polychaete, ca. 20 segments. Notochaetae, simple, transverse across dorsum. Neuropodia lobate, neurochaetae oblique to body axis, otherwise similar to notochaetae. Chaetae possibly flattened, otherwise simple. At anterior both notochaetae and neurochaetae reduced in size, at posterior neurochaetae somewhat more elongate. Details of head not known. No jaws. Gut straight, flanked by massive musculature.
Stratigraphic and geographic range.—Buen Formation (Stage 3 of provisional Cambrian Series 2, equivalent to Nevadella Zone ), Peary Land (North Greenland).
