In addition to the holotype the new species is represented by: MCZ 4100, a skull and jaws; MCZ 4099, partial skull and jaws; MCZ 3777, jaws and some postcranial scraps; MCZ 4102, in- complete jaws; MCZ 4163, postcranial materials. The holotype skull is incomplete in the premaxillary area, but total length was approximately 78 mm from snout to the level of the posterior end of the squamosal arch, 68 mm to the condy

The holotype skull is incomplete in the premaxillary area, but total length was approximately 78 mm from snout to the level of the posterior end of the squamosal arch, 68 mm to the condyle. The lower jaw length is 64 mm. In MCZ 4100 the comparable figures are 73, 70, and probably 62 mm (the jaw is incomplete posteriorly). The materials of MCZ 4099, MCZ 3777, and MCZ 4102 are comparable in size. The postcranial material of MCZ 3777 (to be described in the next paper in this series) is comparable in nature to equivalent elements in P. lewisi except for smaller size, and the postcranial elements of MCZ 4163 are similar. In all major features the skull and jaws are comparable to those in P. lewisi; skull proportions are closely comparable and the sutural pattern is similar, except that in P. ?ninor the lacrimal and prefrontal are somewhat more expanded dorsally at the.
