In only one sknll of all those examined have I seen the arrangement 

 referred to in the title of this Paper. The specimen is a male British (?) 

 skull which I found in the Museum of the Dublin University. There 

 is no history of the specimen, which is numbered 29 in the collection, 

 and which, in the late Dr. Ball's manuscript catalogue, is marked 

 " Skull purchased. — J. Abell's." The skull is a strongly marked one, 

 ■with prominent supra-orbital ridges, having on the left side a supra- 

 orbital foramen, and on the right a groove. Prom these pass up- 

 wards and outwards, on each side, deep grooves, wherein lie the 

 supra-orbital nerve and artery, and this vessel, on the left side, 

 seems to have ended by dipping into the bone. The nasal bones are 

 very large and prominent, and there is a high Wormian bone on each 

 spheno-parietal suture. The exoccipital, on its lower side, sends out flat, 

 paraoondyloid spurs on each side, which overlap the groove for 

 the occipital artery ; but they have no cartilage encrustations, as 

 in the case described by Uhde (Archiv fUr Klinische Chiriu'gie, 

 viii. 1). The aKsphenoid has on each side a foramen in the 

 middle of its temporal crest. The processus tubarius of the ento- 

 pterygoid (Rebsamen, Monatschrift fiir Ohi'enheilkunde, 1868, 

 IS'o. 3) is unusually extended as a thin lamella, backwards and out- 

 wards, and projects shai'ply on the lower sui-face of the hinder acces- 

 sory root of the great wing. The side of the spina angularis completes 

 the articular cavity for the mandible which it has touched. The pala^ 

 tine surface shows some irregularity of suturation ; the left horizontal 



* A Japanese skull, with an approach to the arrangement here described, but 

 the hamulus lachrymalis is very short, and hence there is 0"25" between the malar 

 and jugal bones.
