Kabylites is a narrow, straight shelled Lower Cretaceous ancyloceratid resembling Bochianites

Bochianites

Bochianites is a straight shelled ammonite which lived from the Upper Jurassic, Tithonian, to the Lower Cretaceous, Hauterivian. The shell long, narrow, moderately expanding; smooth or with weak to strong oblique annular ribs. Sutural elements short and boxy...

in general form. Kabylites differs from Bochianites in having an umbilical lobe more or less the same size as the first lateral lobe. In Bochianites the umbilical lobe is much reduced in size.

Kabylites, which is known from Europe, north Africa, and Japan, also follows Bochianites sequentially, first appearing the the Barremian

Barremian

The Barremian is an age in the geologic timescale between 130.0 ± 1.5 Ma and 125.0 ± 1.0 Ma). It is a subdivision of the Early Cretaceous epoch...

 and continuing into the Lower Aptian

Aptian

The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous epoch or series and encompasses the time from 125.0 ± 1.0 Ma to 112.0 ± 1.0 Ma , approximately...

. Bochianites lasted from the Tithonian at the end of the Jurassic to the Hauterivian

Hauterivian

The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous epoch or a stage in the Lower Cretaceous series. It spans the time between 136.4 ± 2 Ma and 130 ± 1.5 Ma...

which just precedes the Barremian.
