You seem to have mastered the taxonomic names fairly well, however, you do not capitalize the species name, just the genus. Example - Dendrobates auratus. Also you are missing the second "e" in cinerea. FYI, taxonomic or scientific names should appear in italics.
Stephen, when writing taxonomic names you abbreviate the genus, not the species. So what you should've wrote is -
3 x False Tomato Frog (Dyscophis guineti)
20? x Golden Sedge Frog (Hyperolius puncticulatus)
4 x Marbled Burrowing Toad (Scaphiophryne marmorata)
4 x West African Fire Frog (Phrynomantis bifasciatus)*
3 x Red Spotted Toad (Anaxyrus (Bufo) punctatus)
1 x Chacoan Horned Frog (Ceratophrys cranwelli)
3 x Dyeing Dart Frog (Dendrobates tinctorius)
6 x Asian Painted Bullfrog (Kaloula pulchra)
5 x Spiny Reed Frog (Afrixalus fornasini )
Also you should only abbreviate the genus if you have already used it once within a paragraph/list and on the same page. Example below.
*Are sure you have Phrynomantis bifasciatus and not P. microps? P. bifasciatus is from East Africa and P. microps is from Western Africa. There are examples of both species in my albums. Also there is a "Meet the Frog" article on P. bifasciatus, with a link to the article on the left.
