I've seen toads offered as "Bufo marmorata" on the internet (couple of companies) and at a local petstore. Bufo marmorata doesn't exsist and the toads look like they belong to the Rhinella complex. They're not Bufo marmoreus or Hyla marmorata. According to most of the shops offering this so called B. marmorata, the toads should come out of Suriname. If that's so they could be Rhinella (of Bufo) humboldti or merianae. I've only seen one picture of humboldti and none of merianae. Hopefully somebody can help me identify these toads.

The picture of humboldti:

Some information about Rhinella complex:
Arquivos de Zoologia - Taxonomic revision of Rhinella granulosa species group (Amphibia, Anura, Bufonidae), with a description of a new species

Google "Bufo marmorata" to see the shops which are offering this toad and to see the pictures. (You'll also see other topics about this matter on caudata and a Dutch frogforum)

and a picture of one of my animals:
