one drawn between the anterior point of the frontolacrymal articu- 

 lation and a point five milHmeters. above the apex of the superior 

 mandible. 



3 The maxillopalatines are spongy bones, being attached to the 

 nasals and nasal septum in the rhinal chamber, merging into each 

 other anteriorly only, being produced posteriorly, parallel and sepa- 

 rate, as far as an imaginary line joining the anteroinferior angles 

 of the ethmoidal wings. 



4 A circular foramen exists on either side, immediately beyond 

 the maxillopalatine plate of the maxillary. 



5 The vomer is a narrow plate of bone, curving upward, then 

 forward, to terminate in a free pointed extremity. More than its 

 half lies between the maxillopalatines. Behind, it is anchylosed 

 with the palatines. 



6 The interorbital septum has an elliptical fenestra in it of some 

 size. 



7 The canal for the passage of the olfactory nerve is double. 



8 The lacrymals are freely articulated in the adult ; and have 

 small additional pieces at their outer extremities. 



9 The basisphenoidal processes are present but rudimentary, not 

 reaching the pterygoids. 



ID The outer posterior angles of the palatines are rounded, and 

 for the most part these bones lie in the horizontal plane. 



11 The mandible is without a ramal vacuity (negative char- 

 acter). 



12 The axial skeleton contains forty (40) vertebrae; the first 

 pair of free ribs is attached to the 13th; the dorsal vertebrae are 

 freely moveable upon one another ; the 20th vertebra is the first 

 one that anchyloses with the pelvis ; the 36th is the anterior free 

 coccygeal vertebra; there are six (6) free coccygeal vertebrae and 

 a large pygostyle; there are nine (9) pairs of ribs in all, the first 

 two pairs and occasionally the last one are without unciform ap- 

 pendages ; the first two pairs are free ; the last two pairs articulate 

 with the anchylosed vertebrae beneath the ilia ; seven pairs, inter- 

 mediate, articulate with the sternum through haemapophyses. 



13 The preacetabular surface of the pelvis is double the extent 

 of the postacetabular ; the ilioneural canals are sealed over ; the 

 anterior fourth of the pubis closes in the obturator foramen, the 

 hinder three fourths of this bone is free, attached only to the 

 ischium by ligament ; a considerable space exists between the two 

 portions.
