Henry Augustus Pilsbry was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial mollusks, and others.
James Henry Ferriss (1849-1926) was an American politician and amateur conchologist. According to Henry Augustus Pilsbry, Ferriss was "the fore-most of American landshell collectors... as a collector he has probably never been surpassed."

Sonorella neglecta is a terrestrial pulmonate gastropod mollusk in the subfamily Helminthoglyptinae. Sonorella is a genus of large land snails consisting of over 80 species, with new ones continuing to be described. The shells typically differ only rather subtly, but proportions of the genitalia differentiate species. The genus is distributed in the southwestern USA and northern Mexico, with individual species often restricted to a single mountain massif or to a small part of one. Sonorella neglecta is such a narrow-range endemic from the Chiricahua Mountains. Its official vernacular name is the Portal Talussnail.
