ICHTHYOLOGICAL FAUNA OF SUJIBAWA. 
Java, beirg thus about one half; 10 are new to science; the rest 
doubtful. 
One species X have considered it necessary to place in a new ge¬ 
nus, which I had previously established in 1844, but of which I have 
not yet published the characters. It is a genus of Scisenoiedes, 
which, related to the Scolopsides, is chiefly distinguished from them 
by fcbe presence of 4 tusks in the upper and 2 in the under jaw, as 
well as by the non-tliorned or thorn formed extremities of the os 
suborbitale. In my Contributions to the Medical Topography of 
Batavia I have named the first species of the genus discovered by 
me, Heterodon xonatus, which name I afterwards changed into Ile- 
terognathodon wanthopleura , as more descriptive of the genus and 
species. Heterognathodon bifasciatus of Bima is the second species 
belonging to this new genus, but I believe it is the same species as 
Scolopsides caninus Cuv. Val. which is given in the celebrated His¬ 
toric naturelle des Poissons at the end of the list of the species of 
Scolopsides. 
Of some of the species already known to science I have drawn up 
new diagnoses, even as I have done of some doubtful species. I 
must still lament that, from my unavoidable separation from the 
scientific world, I am not in a condition to lithograph the new spe¬ 
cies. X must await my return to Europe to publish my already 
partly completed Fauna Archipelagi Indici Iehthyologica. The ef¬ 
forts made by me with the government of Netherlands India for 
its publication have not only not been attended with the desired 
result, but, followed by a transference from Batavia to Samarang 
and Surabaya, have placed me even beyond the possibility of apply¬ 
ing to the service of ichthyological science my cabinet, collected by 
the labours of many years and at a great cost. Batavia, but a short 
time past the centre of science in Netherlands India, shall speedily 
be so no more. The scientific periodicals, the Tijdschrift voor Neer - 
landsch Indie, the Natuur en Geneesknndig Archief voor Neer - 
landsch Indie , the Indisch Magazyn, on whose existence these pos¬ 
sessions might pride themselves, have all fallen to the ground. The 
year 1848 will be noted in the history of Netherlands India as the 
last year of the decennium of its scientific activity. May the time 
come when science shall be again protected and supported here a- 
gainst the unfavorable influences which, in the midst of her bloom, 
have by little and little undermined and menaced her with total des¬ 
truction.
