WAAGEN : CAUBONIFEEOUS AMMONITES, &C. 7 



point, and being limited by a very short and narrow external saddle ; its 

 situation is on the sides of the shell. The whole of the siphonal lobe 

 is shifted towards the front, and thus appears — though in reaUty much 

 longer — considerably shorter than the first lateral lobe. The lateral 

 lobes are twelve in number, the three fiirst of them are divided into two 

 broad terminal, and two small lateral, partitions ; in the following nine, 

 which gradually get smaller towards the umbdieus, the lateral partitions 

 are wanting. The saddles are all narrow and rounded. 



Goniatites primas is very nearly allied to Gon. Orlignyanus, Vern. 

 and Keys., but is easily distinguishable by the lobes, which are much 

 more complicated in the Indian species. There is but little doubt that 

 the two mentioned forms compose a separate group in themselves, 

 which is very likely of generic value, but the materials for the present 

 at my disposal are too small to establish the new genus. That it 

 would be wrong simply to refer those forms to the Ammonites or 

 ClyAonites is clearly shown by the lobes, which exhibit in the siphonal 

 lobe a quite different arrangement from any lobes as yet known in 

 the true Ammonitidm, 



It is very remarkable in science, how often statements are made 

 raising questions which are for the moment apparently solved. Then 

 these solutions may be proved to be wrong, but still the statements have 

 so much permanence of truth that they never again disappear entirely ; 

 but are discussed, are re-stated, and are often rejected, until finally some 

 definite, and for the most part affirmative, solution is established. The 

 early investigators would seem to have instinctively felt the truth, while 

 they mistook the proofs of their statements, untd later and fuller investi- 

 gation detected the real proofs for the old assertion. This is exactly the
