Taxonomic discussion: Lithocircus vinculatus Müller 1856 p. 484; Müller 1858 p.30 pl.1, figs.1-7. In 1859 Müller transferred this species from Lithocircus to Acanthodesmia as his 1856 paper had suggested Lithocircus to be for species with a single ring -dbl

Original description: Mehrere untereinander verbundene Kieselbänder-Reifen in verschiedenen Ebenen bilden das Gehäuse, von dessen Leisten nach aufsen Zacken und Aste abgehen. Das Gehäuse besteht nämlich nur aus den Leisten zwischen 4 grofsen Lücken, welche den Maschen anderer Polycystinen entsprechen. Innerhalb des Gebälkes, nicht ganz in der Mitte, sondern an einen der Balken angelehnt, schwebt der weiche farblose Thierkörper von einer häutigen Capsel umgeben, ohne innere kieselige Theile, nach allen Richtungen seine Strahlenfäden ausschickend, welche sich zum Theil an die Aste der Reifen anlehnen. Durchmesser des Gehäuses 1/12"'. Mehrmals in gleicher Form beobachtet.

Translated description: Skeleton constituted by numerous irregularly joined rings distributed in different planes, from which arise external spines and branches. In between this structure, there are some large gates that correspond to the meshes of the other polycystins. Inside the skeleton, not exactly in the middle, but close to a bar, is located the soft transparent living part surrounded by a skin-like capsule, without internal siliceous components, extending in all direction some radial threads that are sustained by the branches of the ring. Many identical forms observed. (In German. (Translation by J.P.C.)
