Plate XIX 
Mgure 1. Lilloeltia nierlonyarwoodi Crickmay sp. nov., holotype, lateral aspect, 1 natural 
size. Mouth border restored in outline from about one-third of it preserved 
and by the analogy of the other species of this genus. Periphery restored 
purely on basis of proportional method. This is unreliable when used for 
extrapolation, especially on the ultimate whorl of ammonites. So this outline 
is intended only to complete the picture and so elucidate the interpretation 
of the specimen. Ornament is seen 1 and IJ whorls behind mouth border.
