Miers, who in 1886 placed Hypopeltarium together with Gomeza in a legion Corystoidea, recognized that Hypopeltarium was nearly allied to Atelecyclus, and that these approached the Cyclinea, while Gomeza was a typical Corystoid. Alcock includes in his subfamily Atelecyclus M.-Edw., Erimacrus Benedict, 1892, Hypopeltarium Miers, Pliosoma Stimpson, 1862, Telmessus White, 1846, Tr achy car cinus Faxon, 1893, and Tricho-peltarium A.

Miers considered that the name Peltarion was preoccupied, apparently because in 1844 Fischer de Waldheim had named a genus of Coleoptera, not Peltarion but Peltarium. He distinguishes the genus from Atelecyclus " by its narrower, three-spined front, the spinuliferous, not dentated, antero-lateral margins of the carapace, and the shorter, more truncated merus [fourth] joints of the exterior maxillipeds."

Of the Crustacea, plate 8 is quoted by White in 1847. 2 The genus and species are sometimes assigned to Hombron and Jacquinot, who appear to have been both engaged in collecting the specimens obtained by the expedition ; but as the figures of the Crustacea are attributed to Jacquinot by Lucas, who drew up the descriptions, there is nothing on which Hombron'a claim to authorship can properly be founded. |
