330 APPENDIX. 



appears, from the materials submitted to my examination, 

 to be the development of twenty-four, instead of twenty 

 molar teeth : although, these, as in the Indian species, are 

 ultimately reduced to eight, two on each side of both upper 

 and lower jaws. 



With regard to the Dugong of the Red Sea, for which 

 the distinguished Naturalist and Traveller Ruppel, has 

 proposed the name Halicore Tabernaculi, ei in case it 

 should actually prove distinct from the Dugong of the 

 Indian Seas;" # it is certainly distinct from the species 

 here described. The scapula would seem to differ from 

 that of the Halicore aus trails, and to resemble that of the 

 Halicore indicus, inasmuch as its upper border forms the 

 same elliptical curve. f 



The more obvious osteological characters of the genus 

 Halicore, are described as they present themselves in the 

 Dugong of the Red Sea, but without comparison with those 

 of the Halicore indicus. Dr. Soemmerring m his observa- 

 tions prefixed to Dr. RiippePs description, says that the 

 identity of the Halicore Tabernaculi with the Indian 

 species scarcely admits of doubt. J 



He describes an individual in the stage of dentition, 

 when the ante-penultimate molar is retained with the last 

 two molars, but is reduced to small size, e sehr klein \ In 

 the old males, and even in females of the Dugong of the 

 Red Sea, the upper incisive tusks project two inches from 

 the gums. In this respect the Red Sea Dugong deviates
