Remark: Eschmeyer and Bailey in Eschmeyer (1990:70) changed the spelling of the name from <i>Coelorinchus coelorhincus</i>  (or <i>Coelorhynchus coelorhynchus</i>) to <i>Caelorinchus caelorhincus</i>, based on their interpretation of the name; <i>caelo</i> (an awl or engraving tool) made more sense than <i>coelo</i> (hollow).  Iwamoto had followed their spelling since that time.  However, Dr. Dirk Nolf (Institut royal des Sciences naturelles de Belgique) has informed him (in litt., 8 April 2003) that the name should be spelled with the dipthong <i>oe</i> based on the following logic: Giorna’s paper is in French, a language that does not have the dipthong 'ae'.  Giorna (1810:179) writes: "Le Coelorinque-Coelorinchus, the first two words being French, the last Latin. The dipthong 'oe', logically must be the same in the two.  Since the first name is in French, the second can only be spelled with an 'oe'. Nevertheless, revisiting the issue, Iwamoto, Eschmeyer and Fricke showed that the species should be written 'cae' (May 2008, email exhchanges).
