TROPITIDAE Mojsisovics 



CELTITINAE MojsisOvics 



Paraceltites Gemm. 



The genus Paraceltites has been estabhshed by Gemmellaro^ for 

 discoidal, very evolute shells, with transversal straight ribs ending 

 before they reach the venter and becoming more numerous and sig- 

 moidal on the larger whorls; body chamber longer than one whorl, 

 simple lobes consisting of an undivided siphonal lobe, one lateral lobe 

 and a second one on the umbilical wall, and two saddles, all of them 

 rounded and simple. 



The type of the genus is P. Hoeferi, from the Sosio beds. 



Gemmellaro considered Paraceltites as belonging to the Tropitidae 

 and as being especially similar to Celtites, although the latter one has 

 a divided siphonal lobe. This view has been accepted by J. P. Smith^ 

 who regards Paraceltites as the oldest member of the subfamily Celti- 

 tinae. 



Frech^ does not share this opinion but tries to unite Paraceltites^ 

 with Paralecanites Diener^ but this view is opposed by Diener,® Hyatt 

 and J. P. Smith^, who base their objections on the difference in the 

 form of the siphonal lobe which in Paraceltites is undivided while in 

 Paralecanites it has a median saddle; and on the difference in orna- 

 merjtalion. 



Paraceltites is a widely spread genus. It was originally described 

 from the Sicilian Sosio beds, but later on it has been found in the 

 Pyrenees.^ The species, however, could not be determined. It was 

 also shown to exist in Croatia^ where Paraceltites Hoeferi occurs in a 

 sandstone and is associated with a number of ammonoids identical with
