alveolaria). A maxillary tuberosity is not present in the adult, but there is a 

 pointed projection, the pterygoid process, behind the last alveolus. The nasal 

 surface bears a short turbinate crest on its anterior part, behind which it is deeply 

 concave and forms the lateral waU of the maxillary sinus. The palatine process is 

 short, wide behind, and moderately arched from side to side. The anterior palatine

foramen is situated at or close to the transverse palatine suture and about midway 

 between the median suture and the alveolar border. The palatine groove is dis- 

 tinct. The large alveolus for the canine tooth is completed by the premaxilla. 

 The small alveolus for the first premolar is separated from the preceding one by a 

 small interval. The next two consist of anterior and posterior parts for the roots 

 of the teeth. The fourth and fifth are much larger and are divided into three
