416 Mr ANSTED, ON A NEW GENUS 



some very small trilobites. Besides these, there are two species of a 

 wenus which has generally been considered identical with goniatites, 

 altliough it appears to depart very widely from the type of that curious 

 and well-known group. 



In the Annales des Sciences Naturelles, for 1834*, will be foxmd the 

 translation of a paper by Count Miinster, announcing the discovery 

 of a new genus, which he calls Clymenia, and which he found among 

 several new species of goniatites, in the transition limestone of the 

 Fichtelgebirgef. It is to this genus, hitherto unknown in English 

 Palaeontology, that the newly-discovered Cornish fossils must be re- 

 ferred ; although there appears to be so much difference in some respects, 

 that they may possibly form a sub-genus, peculiar to the formation in 

 which they occur. 



The name Clymenia, however, is peculiarly unfortunate, both because 

 it is already appropriated, (for it designates one of Cuvier's genera of 

 Annelides,) and also from its entire want of analogy with all other 

 names of fossil cephalopods. As it must be abandoned, I would pro- 

 pose to call the genus Endo.iip/io7iifes, which has the advantage of 

 indicating the most remarkable and important character — the ventral 

 position of the siphuncle ; while at the same time it sufficiently re- 

 sembles the names of allied genera, and by a slight alteration of the 

 first two syllables, might be applied to mark tlie different positions 

 of the siphuncle which cliaracterise ammonites, nautilites, &c. 



The peculiar character of this genus is, as I have already remarked, 

 tlie position of the siphuncle, in which it differs both from ammonite 



* When my paper was read before tlie Society in February, I was not aware of the ex- 

 istence of this notice in the Annates des Sciences. It is to Professor Phillips that I am 

 indebted for the reference ; and he has already made use of it in the article " Goniatite," in 

 the Penny Cyclopedia. 



+ These hills are situated in the South-eastern part of Germany, to the East of the 

 Maine, and not very far North of Nuremberg. The central ridge is of granite and the 

 transition limestone.
