Brachynra proper. To the Atelecyclidse lie assigns the geuera 

 HupopeUurlon and Atdeciiclus. Miers, who iu 1886 placed Hyfjo- 

 peltarium together vvitb Oomeza in a legion Corystoidea, recognized 

 that Hiipopeltarium u as nearly allied to Atelecyclas, and that these 

 approached the Cyclinea, while Gomeza was a typical Corvstoid. 

 Alcock includes in his subfamily Atelecyclus M.-Edw,, Erimacrus 

 Benedict, 1892, Hiijjopeltarium Miers, Pliosoma Stimpson, 1862, 

 Telmessus White, I84t), Trachycurcinus Faxon, 1893, and Tricho- 

 peltarium A. M.-Ed wards, 1880.

Miers considered that the name Pdtarion was preoccupied, 

 apparently because in 1844 Fischer de Waldheim had named a 

 genus of Coleoptera, not PeUarion but Peltariam. He distinguishes 

 the genus from AteUcyelus " by its narrower, three-spined front, 

 the spinuliferous, not dentated, antero-lateral margins of the cara- 

 pace, and the shorter, more truncated merus [fourth] joints of the 

 exterior maxillipeds."

 I'Oceanie,' 1837-1840, 'has a general titlepage dated 1842-1853. Of the 

 Crustacea, plate 8 is quoted by White in 1847. 



^ 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's 

 claim to authorship can properly be founded.
