Habitat. — Abundant in both soft and hard varieties of bine shale at the Castle, East 

 and West Rocks, and in sandstone from the same localities, St. Andrews, where it also 

 occurs in various shells, bivalve and univalve. In their galleries in the shale at St. 

 Andrews they are accompanied by the boring Sipunculas, young examples of Dodecaceria 

 and Pholoe, and by Amphicora (Oithonia) Fabricii. Howth, Blacksod and Clew Bays 

 (Southern). Torquay (Elwes). 



Abroad it is cosmopolitan. Spitzbergen (Malmgren, Fauvel). Denmark, Sweden, 

 Norway, Iceland, the North Sea, coast of France under Lithoth amnion, in shells of

Head (Plate LXXXIX, fig. 4) with the median region (prostomium) elevated and 

 terminating anteriorly in two rounded lobes, with a deep median notch. The ridge runs 

 backward and terminates in an elevation about the anterior border of the third bristled 

 segment. At the sides of the ridge is a considerable amount of dark pigment, which 

 occasionally remains in spirit-preparations, whilst on it are four small black eyes, though 

 this number is not constant. The lateral regions are formed of the peristomium as usual
