does not necessitate the abandonment of the latter name. Buckman l 

 discusses an analogous case in Brachiopods in these words: "On 

 the ground that Cryptopora was pre-occupied by Cryptoporus, and 

 Atretia by Atretium, Fischer and Oehlert proposed and used the 

 name Neatretia. But though in the case of trivial names 

 cryptoporus and cryptopora would have to be regarded as synonyms, 

 because the termination must be governed by that of the generic 

 name, in the case of the generic name itself there appears to be no 

 necessity to make any change of termination ; so that Cryptopora and 

 Cryptoporus as generic terms ought to be quite distinct enough. It 

 is true that such changes of generic termination were commonly made 

 at one time ; but such alterations are now discarded in favour of the 

 original selection." Unless, then, Clavigera was accidentally or 

 intentionally employed as a substitute for Claviger (in which usage 

 it would be a synonym of Claviger), prior to the validation of the 

 name by myself for the Brachiopods under question, the name 

 must stand for the latter group, and Hectoria becomes a synonym. 



As originally proposed by Hector in 1878, 2 Clavigera was a genus 

 coslebs, that is, it was a genus without any species. Hector partly 

 remedied this omission in 1886, 3 when he figured two species, but he 

 omitted to name them. In 1913* I discussed the genus and published 

 plates which had been prepared and printed by Hector many years 

 before, and gave names believed to be manuscript names of Hector to 

 four species, viz. Clavigera bisulcata, C. cuneiformis, C. gracilis, 

 C. tumida. Although my intention was to give credit to Hector, the 

 responsibility rests with myself, and according to the opinions 

 published by the International Commission on Zoological Nomen- 

 clature responsibility takes precedence over credit in publishing new 

 names. In the publication referred to I did not select a genotype, 

 nor has Trechmann designed a genotype for Hectoria. These omissions 

 I now rectify as follows : Clavigera, Thomson, 1913 ; genolectotype. 

 Clavigera, bisulcata, Thomson. Synonym Hectoria, Trechmann, 19 18 ; 

 genolectotype Hectoria cuneiformis, Trechmann = Clavigera cuneiformis, 

 Thomson. 



Hectoria tumida Trechmann is a synonym of Clavigera tumida 

 Thomson, and Hectoria bisulcata Trechmann of Clavigera bisulcata 

 Thomson. Should any subsequent author consider that Clavigera 

 cuneiformis and C. bisulcata are not congeneric, Hectoria may stand for 

 the former. C. bisulcata is Triassic and C. cuneiformis Jurassic. 



Rastelligera equally with Clavig era was validated by me in 1913, 

 and the sole species therefore becomes the genotype, viz. Rastelligera 

 elongata, Thomson, of which Spiriferina diomedea, Trechmann, appears
