 p. 13. 



1853. Xantho ttiberculata, H. Q. Couch, in Bell's Brit. Crust.

Bell must have forgotten that two years previously to the 

 publication of the last part of his work he had named 

 a species Xantlio Couchii which he, in his work, calls X. tu- 

 berculata. The type was found by Couch in " crevices of 

 Eschara foliacea, in deep water off the Runnell Stone in 

 Mounts Bay." Polperro (Laughrin, in Mus. Nor.) ; Ply- 

 mouth, frequent in 4-45 fathoms (Bate, and Garstang t ii.
