Diagnosis Smooth or transversally striated, slender, orthoconic baltoceratids with narrow, tubular siphuncle. Siphuncle is eccentric with rSP of more than 0.2, and with rSD ≈ 0.2 or less. Septal necks are orthochoanitic. Endosiphuncular or cameral deposits are not known (adopted from Kröger et al. 2007). : Published as part of Kröger, Björn & Pohle, Alexander, 2021, Early-Middle Ordovician cephalopods from Ny Friesland, Spitsbergen - a pelagic fauna with Laurentian affinities, pp. 1-102 in European Journal of Taxonomy 783 (1) on page 58, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/5793422 : {"references": ["Kroger B., Beresi M. & Landing E. 2007.
