==Goose barnacles== 
 I am currently writing an article that I intended to call Capitulum (or "Capitulum (zoology)" or somesuch name). Capitulum is according to WoRMS a monoypic genus in the family Pollicipidae which has the species Capitulum mitella (Linnaeus, 1758). Wikipedia does not currently have that family. We have a family Pollicipedidae and that contains a genus Pollicipes and the species  Pollicipes mitella (Linnaeus, 1758). There is no mention of this being synonymous with Capitulum mitella. I think it is a mess and am unsure how to proceed. (My main source, the NHM, uses Capitulum mitella.)
