_ In the years 1895, 1904 and 1905 I contributed to the present 
publication an account of the teratological deviations collected 
at Buitenzorg in the Botanical Gardens and environs. The 
majority of those monstrosities had been collected by Mr. Smith, 
myself having had only in 1892 an opportunity of co-oporating 
in the work. Hereby I present another paper in which our 
newest findings are described. Just as before the material has 
been examined by both of us, in the fresh state by Mr. Smith, 
by myself after it had been sent to Holland, dried or immersed 
in alcohol. Much care has been spent on the figures this time. 
The javanese draughtsmen Natadipoera and Raden Samadi 
have produced really artistic drawings, which, reproduced at 
Leyden with the skilful burinpin of G. de Blaauw, inevitably 
have lost part of their tenderness which only a lead-pencil is 
apt to create. 
_ With gratitude we ought to mention the interest which our 
teratological work has found with both naturalists and cultiv- 
ators on Java. The gentlemen C. A. Backer, J. H. Heyl, 
Krimer, J. P. Moquette, S. Schoggers, Schott and C. Suermondt 
have laid us under an obligation by their sendings, and in 
thanking them cordially we cannot help wishing that they and 
others might also in the future be kind enough oe continue 
the work of collecting on our behalf.
