is as little resemblance to Gamier iceras, with flat and rounded 

 umbilical border and different suture-line, as to the Valanginian 

 Platylenticeras and Tolypeceras, with a very characteristic small 

 first lateral lobe. Even Gamiericeras subclypeiforme Mila- 

 schewitsch, in Nikitin, 1 which comes closest in suture-line, is merely 

 an involute G. catenulatum (Trautschold), and the new genus 

 Pseudogarnieria nov. (type : Oxynoticeras undulato-plicatile 

 Stchirowsky 3 ) is now proposed for this group. The ' Hoplites ' 

 found in the same beds : namely, Proleopoldia, gen. nov. (group 

 of Hoplites Jcurmyschensis Stchirowsky) 3 can perhaps be matched 

 only by the Patagonian ' Leopoldia ' described by Favre 4 and by 

 the genus Hatcher iceras Stanton. 5 But the latter are associated 

 with Favrella, ■ which resembles Paraboliceras, Kossmatia, and 

 Blaufordiceras. Uhlig G thought that Berriasella and ' Streblites ' 

 belonged to the same assemblage, wherefore the Upper Jurassic and 

 not Cretaceous age of the Russian beds in question is almost certain. 

 The three genera of the Craspedites beds of the ' Aquilonian ' 

 might, of course, still be considered to be boreal equivalents of 

 such southern types as Proniceras and Haploceras, with simpli- 

 fying suture-lines, and referred to the Tithonian. But it may be 

 useful to give here a record of the sequence at Kachpur, as it 

 appears to be represented by a number of specimens in the collec- 

 tion of the late J. F. Blake. There may have been confusion of 

 beds, but the specimens are numbered in the following order : — 



4-5. Gamiericeras subclypeiforme (Milaschewitsch). 



Craspedites nodiger (Eichwald). 



(Garnierieeras-catenulatum fauna missing.) 

 3. Epivirgatites nikitini (Michalski) and allies. 



Epivirgatites aff. dorso2>lanus (Vischniakoff) Michalski. 



Craspedites cf. subditus (Trautschold). 



Kachpurites fulgens (Trautschold). 



Kachpurites subfulgens (Nikitin). 

 2. Virgatites virgatus (von Buch) and Virgatites sp. 



Epivirgatites nikitini and spp. 



Epivirgatites, sp. nor. (scythicus Michalski, pars). 



Craspedites cf. okensis (d'Orbigny). 



Kachpurites, sp. nov. aff. fulgens (Trautschold). 

 1. Virgatites virgatus (von Buch) and spp. 

 Bituminous Schists : 



Pseudovirgatites cf. schlosseri Schneid, and spp.

 Holcosteplianus hobler-hillensis Favre; but this appears to be rather of Lower 

 Spiticevatan (or basal Cretaceous) age.
