This is a skull without the lower jaw. It is marked, 

 " Tasmaniaii from Hobart." The Curator states that it was 

 received from " Professor" T. H. Hume. Part of the right 

 zygomatic arch is wanting. The bones are much polished, as 

 if they had been subjected to a good deal of handling. The 

 lines on them are distinct and the ridges are prominent. It 

 appears to be the skull of an adult male. It weighs 20ozs. 

 139grs. avoirdupois. 



Norina verticalis. — The skull is long. Although the parietal 

 eminences stand out as fairly prominent bosses, the ci'anial 

 outline is rather oblong or ovoid than pentagonal in form. 

 The triangular area on the frontal bone in front of the bregma, 

 noted by Turner in the specimens he has described, is fairly 

 well marked ; and the flattened areas that bound it laterally 

 pass backwards over the coronal suture to the parietals and 

 stop near the posterior part of the parietal eminences. 

 Anteriorly these flattened areas run between the frontal 

 eminences and meet niesially between the glabella and the 

 anterior end of a low broad ridge that runs forwards in the 

 middle line from the bregma. The frontal eminences are 

 well marked and are situated between the flattened areas 

 mentioned above and the temporal curved lines. These 

 curved lines on both sides run backwards and pass below the 

 parietal eminences. Although they are double throughout 

 nearly their whole length in front of and behind the 

 stephanion, only the inferior portion or limb of the ridges 

 seems to be represented. The anterior half of the sagittal 

 suture runs in a narrow groove on a prominent crest, and 

 there is very distinct flattening between it and the parietal 

 eminences on both sides, corresponding with the prolongation 

 backwards of the flattened areas on the frontal boiie. The pos- 

 terior half of tlie suture (PI. viii., fig. 1) runs in the gradually 

 widening groove which is depressed in the central part. The 

 maximum widening and depression occur at the obelion. On 

 the postero-lateral part of the right parietal bone there is a 

 flattened area, 50 mm. by 30 mm. in size, due perhaps to injury 

 or some pathological condition. Below the parietal eminences 

 the side walls slope inwards to a minimum diameter of 

 111 mm., and then outwards to the inferior angle of the
