named several species after Homfray to honour his efforts, e.g. Niobe (Niobella) Homfrayi (Salter, 1866, p. 143, pl. 20, fig. 9.), Asaphus Homfrayi Salter (1866) – now Asaphellus homfrayi (Salter) – see Morris (1988): Lectotype, from Garth Hill, near Porthmadog, and Conularia Homfrayi Salter; undifferentiated Type, also from Garth Hill. [(Salter 1866, p. 354, pl. 10, fig. 11); Salter (1873, p. 18, p. 323); Woods, H. (1891, p. 119)]. From the Clogau Formation of Waterfall Valley near Maentwrog, Homfray also discovered for the first time in Britain, Conocoryphe coronata Barrande, 1846, and another species named in his honour, "Conocoryphe" Homfrayi Salter, subsequently assigned to Ptychoparia, Hawle and Corda, 1847. In 1865 Salter collaborated with Henry Woodward to produce a Chart of Fossil Crustacea. and in the same year published a paper on some Additional Fossils from the Lingula-Flags. in which he named several trilobite species that were subsequently described by Hicks (1872). Salter prepared several of the Decades of the Geological Survey and became the leading authority on trilobites. He resigned his post on the Geological Survey in 1863 and sadly committed suicide on 2 December 1869 by throwing himself into the Thames. He was buried on the eastern side of Highgate Cemetery in an unmarked grave (no.15356). At the time of his death he had barely completed the illustrated 'Catalogue of Cambrian and Silurian Fossils' (q.v.) in the Woodwardian Museum and he left unfinished a 'Monograph of British Trilobites,’ published by the Palæontographical Society (1864–1867). He was elected an associate of the Linnean Society in 1842, made a fellow of the Geological Society of London (FGS) in 1846, and in 1865 was awarded the Wollaston donation-fund by the Geological Society. Fossils named in honour of John William Salter Problematica Salterella Billings, 1861. An enigmatic early Cambrian genus questionably assigned to extinct phylum Agmata? and family Salterellidae Walcott, 1886. The genus is characterized by a small calcareous, apparently septate conical shell and lends its name to the Salterella Grit Member of the An t-Sron Formation which forms a narrow, discontinuous belt, extending along the North-western side of Scotland. Trilobites Salteria Wyville Thomson, 1864 [Family: Raphiophoridae]. Type species, by monotypy, Salteria primaeva Thomson, 1864. Balclatchie Group (Caradoc Series) of the Girvan district, Strathclyde, Scotland. Salterolithus Bancroft, 1929 [Family:Trinucleidae]. Type species: Trinucleus Caractaci Murchison, 1839.
