Lyonsiidae
Lyonsiidae is a family of small saltwater clams, marine bivalve molluscs in the order Anomalodesmata. Description Members of this family have inequivalve, oblong valves that are nearly equilateral. The right valve is more convex than the left, and there are usually no teeth. The ligament connecting the two valves is in an internal groove, and the hinge has a free ossicle. Genera and species The World Register of Marine Species lists the following genera and species in the family: *'' Allogramma'' Dall, 1903 **'' Allogramma elegans'' (Thiele & Jaeckel, 1931) **'' Allogramma formosa'' (Jeffreys, 1882) **'' Allogramma oahuense'' (Dall, 1913) *'' Bentholyonsia'' Habe, 1952 **'' Bentholyonsia teramachii'' (Habe, 1952) *'' Entodesma'' Phillips, 1845 **'' Entodesma beana'' (d'Orbigny, 1853) **'' Entodesma brasiliense'' (Gould, 1850) **'' Entodesma brevifrons'' (G.B.

Pholadomyoida
Anomalodesmata is an superorder of saltwater clams, marine bivalve molluscs. This grouping was formerly recognised as a taxonomic subclass. It is called a superorder in the current World Register of Marine Species, despite having no orders, to parallel it with sister taxon Imparidentia, which does have orders. Description The shells of species in this order are of equal size, as are the muscles that hold them closed, and the margins at the hinges are thickened. The margins of the mantle are also fused, and there is only a single hinge tooth, if any. Families In 2010, a new proposed classification system for the Bivalvia was published in ''Malacologia'' by Bieler, Carter & Coan revising the classification of the Bivalvia, including the order Anomalodesmata.Bieler, R., Carter, J.G. & Coan, E.V.

Arthur Adams (zoologist)
Arthur Adams (1820 in Gosport, Hampshire – 1878) was an English physician and naturalist. Adams was assistant surgeon Royal Navy on board HMS ''Samarang'' during the survey of the islands of the Eastern Archipelago, from 1843 to 1846. He edited the ''Zoology of the voyage of H.M.S. Samarang'' (1850). Adam White collaborated with him in the descriptions of the Crustacea from the voyage. In 1857, during the Second China War whilst serving as Surgeon on HMS ''Actaeon'', he was present at the storming of Canton and awarded the China War Medal. He retired as Staff Surgeon aboard flagship HMS ''Royal Adelaide'' at Plymouth in 1870. He was a prolific malacologist who described "hundreds of new species, most of them unillustrated and insufficiently diagnosed". He partly worked together with his brother Henry Adams (1813–1877) and together they wrote The genera of recent mollusca: arranged according to their organization' (three volumes, 1858). He also wrote ''Travels of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
