(3) Discoporella Busk, 1S59 1 ), given by Busk as " Discoporella Gray". — It is not 

 clear whether this was a deliberate emendation of Gray's name or an accidental misquotation ; 

 but, as has already been remarked by Jullien -), the form adopted by Busk is not valid, 

 as D'Orbigny :! ) had previously introduced Discoporella for Lunulites umbcllata Defrance (now 

 usually placed in Cupularia), and two other species. The use of Discoporella in this sense 

 prevents it from being retained for any member of the Lichenoporidae. 



(4) Defrancia Bronn, 1825. — As pointed out by Gregory *), the only species mentioned 

 by Bronn in the original introduction of the genus is D. (Pelagia) elypcata Lamx. Defrancia 

 and Pelagia Lamx, 182 1 (preoccupied by Pelagia Pér. and Les.), are thus both synonyms of 

 Apsendesia Lamx, 1821, if Gregory is right in stating 5 ) that Pelagia elypcata is the young 

 condition of Apsendesia cristata Lamx, 1821. 



(5) Discocavea D'Orbigny, 1853°). — This genus is distinguished by D'Orbigny from 

 other genera of his Fam. Caveidae by having its zooecia in uniserial radiating lines ; — a 

 character which does not apply to all recent species usually referred to Lichcnopora.
