Jacquin. But the latter name, although well known to the Vienna 

 botanists, having been since applied by Pohl to a South American 

 genus, it has become necessary to recur to that originally given, 

 which may also possibly be set aside if (as there is reason to suspect) 

 the genus should prove to be identical with the Rhincoglossum of 

 Dr. Blume. '* With regard to the genus itself," Mr. Brown ob- 

 serves, " it may be doubted whether Loxotis and Glossanthus ought 

 to be generically distinguished merely or chiefly on account of the 

 difference in the number of their antheriferous stamina, especially 

 as they entirely agree in habit, in which there is something peculiar. 

 It is not a little remarkable, that in some of the more minute and 

 less important differences between them, the intermediate structure 

 or connecting link should be found in a species sent by Dr. Schiede 

 from Mexico (Glossanthus Mexicana, Br. ined.)and that this should 

 be the only plant belonging to Cyrtandraceai hitherto observed in any 

 part of America." 



The twenty-fifth plate, the last of the present part, represents 

 another plant cf the same tribe, Loxonia acuminata, the letter-press 

 relating to which is postponed to the succeeding part. 



Under the head of each plant, Dr. Horsfield has furnished valuable 

 information as to its habit, growth and uses ; the precise localities 

 in which it was found by him, particularly noting the height above 

 the level of the ocean ; its native name, and such other particulars 

 as his long residence in Java enabled him to collect.

March 27th, 1838.— William Yarrell, Esq., in the Chair. 



A Dugong preserved in spirit having been presented to the Mu- 

 seum by Alexander John Kerr, Esq., of Penang, Mr. Owen com- 

 municated to the meeting some notes descriptive of the principal 

 viscera in this remarkable aquatic mammal, and a statement of the 

 relative proportions exhibited by its several parts, in comparison with 

 the dimensions of a Dugong published by Sir Stamford Raffles in 

 the Phil. Trans., 1820, and of two other specimens which Mr. Owen 

 had on previous occasions examined in the Society's collection. From 

 these notes, as given in No. 63 of the Society's ' Proceedings,' the 

 following are extracts. 



Mr. Owen remarks, that "The external form of the Dugong is 

 not so well calculated for moving rapidly through the water as that
