selection — Lamarck — complied with this rule. He chose 

 Anomia terehratula, Lin., to be the type ; thus he may be 

 said to have confirmed Muller and Thunberg. So we may 

 write 



Genus Terebratula, Muller, 1776. 



Geuotype Anomia terehrainla, Linn^. 

 Syu. terebratula, Klein, pie-Linuean. 

 Is on Terehratula, Llhwyd, pre-Linneau, 'v^hich^^Epithyris, Phillips *. 



It is now necessary to identify Terebratula terehratula 

 (Linn^). That author describes and cites figures for his 

 species, thus: — "A. testa obovata Iffivi convexa; valvula 

 altera triplicata, altera biplicata. — Column, purp. 22 f. 1, 

 List. angl. 240 t. 8. f. 46. Klein ostr. t. U. f. 74." 



Of these figures the first and third refer to the same shell, 

 for Colonna used the same woodcut in various places, and 

 Klein copied it. But Lister's figure represents a very 

 different species : it is not plicate, and therefore it does not 

 agree with Linn^'s description f. As the Colonna-Klein 

 fio-ure does, that must be taken as the holotype, which^ in 

 fact, has been the usual practice. 



In 1819 Valenciennes \ gave the name Terehratula Kleini 

 to a species, citing Klein's figures, and quoting as a synonym 

 Anomia terehratula, Linne. In 1850 Davidson § said that 

 the name Tereh. Kleini covered a well-known Bajocian fossil 

 of Kormandy (it is from the Maliere), and he figured, in 

 support of his opinion, a specimen so labelled in the Lamarck 

 collection. 



In 1856 S. Hanley identified Linne's Anomia terehratula as 

 Terehr. perovah's, Sowerby ||. 



In 1864 Deslongchamps followed Davidson's line, making 

 T. Kleini^ Davidson (? Lamarck), a variety of Terehratula 

 perovalis ^. 



Though Lamarck may have thought that the Bajocian 

 fossil was the same as Klein had figured, and so may 

 have ticketed it T. Kleini in his collection, yet it is not 

 the holotype of T. Kleini: the specimen figured by Klein 



* Ann. & Mag. Nat. Ilist. ser. 7, vol. xviii. 1906, p. 322. 



f Lister's smooth non-plicate Terebratulid is from near Grantham, 

 probabh' therefore from Middle Lias, and it has much the aspect of one 

 of the T. punctfita series.
