Genus Fusella M’Coy, 1844
Type species: Spirifera fusiformis Phillips, 1836 , from the lower Visean of Bolland, Yorkshire, England .
Remarks.— Fusella was erected by M’Coy (1844) as a subgenus to include small spiriferides with a fusiform outline and very wide and high cardinal area. Buckman (1908) raised Fusella to genus level, and based on the type species Fusella fusiformis ( Phillips, 1836) , stated it to have a few faint costae in the sulcus. The internal characters of F. fusiformis are still unknown due to the rarity of the species. Brunton and Rissoné (1976) included in the genus Spirifer rhomboidea Phillips, 1836 , from the lower–middle Visean of Great Britain and Ireland, describing its internal characters as an example to those for Fusella . However, S. rhomboidea has no costae in the sulcus. Also the allied Voiseyella Roberts, 1964 , of the Strophopleurinae Carter, 1974, has no costae in the sulcus but is distinguished by disproportionally larger sulcus-bounding costae.
