The locality of the lectotype of Testudo dussumieri Gray, 1831
Frazier & Matyot (2010; BZN 68: 140–143) have attempted to sideline the putative lectotype of the Aldabra tortoise, the Leiden specimen collected by Dussumier, by arguing that it cannot be considered suitable as its provenance is uncertain on both historical and genotypic (DNA) grounds. In relation to the correct name for the species in question, there are two issues they have not considered.
Hoogmoed (BZN 68: 72–77) criticised the paper in Zootaxa by Frazier & Matyot(2010), calling for their conclusions to be considered void.

In a paper I published some years ago (Ramsay et al., 2002) I referred to the speciesas Dipsochelys dussumieri. I would like to clarify that my publication was not meantas validation or particular support for dussumieri over gigantea. Further, havinglooked at the case information, I agree with Case 3463, and offer my support forconservation of the name Testudo gigantea.Additional referenceRamsay, S.L., Hofmeyr, M.D. & Joshua, Q.I. 2002.

With awe I have read the whole of Case 3463. I am quite shocked to see how this casehas developed into a schoolyard brawl. Especially the interference of people whodon’t normally work with the Aldabran Giant tortoise is quite disturbing. Also thefact that scientists let themselves be driven by personal emotion without a scientificreason upsets me. Yet, because this has happened I feel obliged to give my point ofview as well. I consider myself just a hobbyist/layperson. Yet I have read the Code.I have also read the works of both Bour and Frazier.
I wish to state my support for case 3463. As a biologist who is naive to the specificsof scientific nomenclature, I used the name Dipsochelys dussumieri to describe theAldabran giant tortoise, in two publications: Okanga & Rebelo (2006) and Wazala &Okanga (2006).However, having now read the presentation in case 3463, I have been convinced bythe sound arguments and have been made aware of my error in judgment.
The Wildlife Protection Society of India has been actively involved in an enormousvariety of wildlife conservation issues for more than 16 years. As we operate in aregion of exceptional biological diversity, we are continually dependent on the workof taxonomists and systematists, because the species that are ultimately deemed torequire protection and special attention are defined by them. Needless to say, wegreatly respect professionals from these disciplines, and would not think of interferingwith their work.
