At the request of Steve Haddock, I will note here all changes to the list of all valid scientific ctenophore names beginning January 1, 2003.

January 28, 2003 - update log set up; no changes to list.

April 7, 2003 - added some new photograph links, corrected others.

June 10, 2003 - changed my University of Washington affiliation to new UW Dept. of Biology (combined Zoology and Botany).

October 8, 2003 - added correct date to Coeloplana thomsoni Matsumoto, 1999; fixed some links.

November 3, 2003 - changed original author of Order Platyctenida from Mortensen 1912 to the earlier entry mentioned by Komai (1922) = Bourne 1900. Thanks for Tim Siferd of Winnepeg for pointing this out. I have not seen the original Bourne yet.

February 1, 2005 - updated link for Lobatolampea tetragona.

April 5, 2005 - changed family Euplokamidae to Euplokamididae in accordance with ctenophore family names used in Cairns et al. 2002. Small text change introducing Ctenolist including mentioning an additional about 25 known, but undescribed ctenophores, many of which are in the deep-sea.

May 1 and 13, 2007 - added some new photograph links, corrected others.

June 28, 2009 - updated some photograph links, added some new ones.

June 28, 2009 - font change.

November 8, 2010 - added forgotten species Gastrodes komai Dawydoff, 1937 as Lampea komai. Substantially updated the introduction. Updated a few photograph links. (I also rewrote portions of, and added a bunch of links to, the Ctenophores page.)

February 9, 2011 - corrected spelling to Horita for one use of Lobatolampea. Changed date on two questionable species of Callianira, C. diploptera and C. triploptera to Lamarck 1816 (from 1843).

February 3, 2012 - added new species Coeloplana anthostella and Bathocyroe longigula and one old Cestum synonym that had not previously been listed. Added family Aulacoctenidae of Lindsay and Miyake (2007), with genus Aulacoctena, and moved Pleurobrachia latipharyngea Dawydoff, 1946 to genus Bathyctena, as suggested by Lindsay and Miyake (2007). Added several recently-described fossil ctenophores or fossils recently interpreted as ctenophores.

February 14, 2012 - corrected date of Bathocyroe longigula Horita, Akiyama and Kubota, 2011.

May 9, 2012 - linked new image of Callianira antarctica and replaced a number of broken links to images of other species. Added seven new species from Gershwin, Zeidler and Davie, 2010: (new Family Pukiidae) Pukia falcata, Euplokamis evansae, Coeloplana mellosa, Coeloplana reichelti, Bolinopsis ashleyi, Leucothea filmersankeyi, and Ocyropsis vance. Changed authorship of Ocyropsis subspecies maculata maculata and subspecies crystallina crystallina to Harbison and Miller, 1986 to match the other new subspecies created in the same 1986 paper (O. maculata immaculata and O. crystallina guttata).

May 13, 2012 - corrected spelling from Ctenoplana yurii Dawydoff, 1929 to C. jurii Dawydoff, 1929. Dawydoff subsequently (1936) refers to this species as C. yuri, but I have now used the spelling from the original description.

May 15, 2012 - after re-reading many papers about the species of Pleurobrachia, I have synonomized P. rhododactyla with P. pileus, as suggested by Bigelow (1912) and Mayer (1912). I can't explain why I didn't do this long ago. I have also added or changed a couple of new editorial comments in red beside some species names and changed a couple of links to new images.
