There is no question about the type of the genus Kellia, which some years 

 later served also as the type of the genus Tellimya Brown and Oronthea of 

 Leach. Cliironia Deshayes is based on a large Californian species of Kellia 

 in which the hinge is better developed than usual in the genus, having in its 

 best estate two short, so-called cardinals in each valve, one left and two right 

 posterior laminae. Poorly developed specimens of this species have a hinge 

 exactly like the average Kellia suborbicularis, while the latter in exceptionally 

 well-developed specimens shows traces of the extra laminae referred to. As 

 in so many others, the shells of this genus show a diminished development of 

 the hinge correlated with reduced size and greater depth of habitat. Some of 

 the minute abyssal species retain only one small tooth in each valve. The 

 genus Goodalliopsis of de Raincourt and Munier-Chalmas has the same dental 

 formula as Kellia, of which it appears to be merely a small compressed species. 

 The gills of Kellia are normal ; that is, they have both direct and reflected 

 inner and outer laminae. The viscera are contained within the body mass. 



The group may be divided as follows : 



Section Kcllia Turton s. s. Type K. suborbicularis Mtg. 



Shell rounded and inflated, concentrically striated or smooth; with an 

 obsolete amphidetic external ligament and a large, strong internal resilium
