ANGUINOMORPHA
EEL-LIKE LIZARDS

The Anguinomorpha contains five families of lizards that exhibit body elongation and, in many cases, limb-reduction, although not all elongate, reduced-limbed lizards belong to this group and not all anguinomorphs are elongate with reduced limbs, many possessing four well developed pentadactyl limbs. The families may be divided into an unnamed clade containing the Anniellidae and Anguidae, the Xenosauridae, and the Varanoidea, a superfamily containing the Helodermatidae and Varanidae, but there are alternative phylogenies available. The Anniellidae-Anguidae contain 15 genera and 119 species, the Xenosauridae two genera and seven species, and the Varanoidea, three genera and 76 species. The Anniellidae and Xenosauridae are not currently represented in the photo library.

Legend:
Photographic locality. Wherever possible precidence is given to wild specimens from known localitions, wherein the 'photographic locality' relates to the origin of the photographed specimens, rather than the taxon's entire range. The only exceptions are indicated by (captive) or (preserved specimen). These are either specimens photographed in captivity, where the locality given is a general distribution for the taxon, or preserved specimens photographed as biological voucher specimens.

Column D1. Digitized images - the bulk of the library consists of 35mm transparencies (mostly Kodachrome or Velvia) which are gradually being digitized [using Nikon CoolScan 4000 or Plustek OpticFilm 7600i] and stored on hard disc. 'X' indicates that digitized images are available, '[]' indicates that the transparencies of this taxon have yet to be digitized.

Column D2. Digital images - since 2005 digital images have also been taken [using Canon EOS 30D, 40D or 7D]. 'X' indicates that digital images are available in addition to digitized images for this taxon.

ANGUIDAE
ALLIGATOR LIZARDS & THEIR ALLIES

The Anguidae contains three subfamilies: the slow worms and glass lizards of the Anguidae (three genera, 16 species), alligator lizards of the Gerrhonotinae (five genera, 52 species) and galliwasps of the Diploglossidae (six genera, 50 species). The Anguidae is represented in the photo library by three genera and five species, while the Gerrhonotinae is represented by two species from the same genus.
