We suppose that this specimen is a further advanced stage 

 of the Leptoceplialus mirabilis described by BRAUER after a 

 specimen of 71.5 mm. from the Indian Ocean, east of Zanzibar. 



Besides the above described forms the following Leptocephali 

 have been mentioned from the indo-australian Archipelago. 



Their description is so short or insufficient, that we draw 

 the attention on them only for completness sake. 



i. Leptocephalus dentex Cantor. 



Leptocephahis dentex Cantor, Journ. Asiat. Soc. Bengal XVIII. (1849) 1850, p. 1315. 



Described after a specimen of 4 1 /, inches length from Pinang, 

 found in the stomach of Johnius diacanthus. 



2. Helmichthys oculus Peters. 



Helmlchthys ociilus Peters, Monatsber. Akad. d. Wissensch. Berlin, 1866, p. 525. 

 Helmichthys oculus Max Weber, Siboga-Exp. Fische, 1913, p. 65. 



It follows from the description of PETERS that this Lepto- 

 cephalid of 157 mm. length from Ambon was in the regressive 

 metamorphosis to a glass-eel, the body of which was already 

 beginning to be rounded. It may be that it is a larval stage 

 of Congrellus Ogilby or Paramyrus Giinther. 



3. Leptocephalus ceramensis Blkr. 



Leptocephahis ceramensis Bleeker, Atl. Ichth. IV. 1864, p. 123.

Described after a specimen of 212 mm. which was in a bad 

 state, from Wahai, Ceram.

 Leptocephalus taenioides Max Weber, Siboga-Exp. Fische, 1913, p. 66. 



Described after a specimen of 105 mm. from Ambon. 

 5. Leptocephalus hypselosoma (Blkr.).
