The following are some of its British habitats and depths : 

 Off Hebrides, 189 fathoms (Carpenter and Thomson). 

 Off Faroe Isles, 170 fathoms (Carpenter and Thomson). 

 Off west of Ireland, 90 to 808 fathoms (J. Gwyn Jeffreys). 



Mr. David Robertson and others have dredged it off Oban, in Loch Fine, and at Loch 

 Cumbrae. It occurs attached to stones, old shells, and, according to Mr. Jeffreys, 

 occasionally to small sea-weeds and other substances.

This species has been frequently described and illustrated. Its loop is long and 

 reflected, as in Waldheimia, but, from being often found broken, some misconception as to 

 its true nature has been entertained. 



As justly observed by Jeffreys, Waldheimia cranium was mistaken by Fleming, Sars, 

 and some others, for Terebratula vitrea, which has an entirely different apophysary 

 arrangement; and I was myself misled as to its true character in 1853, but soon after 

 corrected my mistake in Appendix, PI. A, fig. 1. 



Wald. cranium was found nearly sixty years ago by Prof. Fleming off Bressay Island, 

 and specimens of various sizes and ages have been dredged in the same seas by Mr. 

 Jeffreys, Mr. Barlee, and some others. Dr. Carpenter obtained it in 170 to 650 fathoms 

 north of Hebrides. Mr. Jeffreys dredged it off the west coast of Ireland (' Porcupine ' 

 Expedition, 1869) ; in the Bay of Biscay and Channel Slope in 30 to 690 fathoms 

 (Jeffreys) ; off Bayonne (Folin,^? Fischer). 



It been has found fossil in the Post-Tertiaries of Norway and Pliocene of Sicily. The
