12. Hemirhamphus erythrorhynchus Lesueur. 



Hemirhamplnis erythrorhynchus I.esueur. Journ. Acad. Nat. Sc. Philad. II. 1821, 

 P- 137- 



Bleeker mentions this fish 3 times (Journ. Ind. Arch. Ill 

 {1848) 1849, p. 67 & 68; Nat. Tijdschr. Ned. Indie II. 1851, 

 p. 214; Act. Soc. Sc. Indo-Neerl. VIII. i860, 13^6 Bijdr. 

 Celebes, p. 47) each time from Makassar, but in his later publi- 

 cations as well as in the „ Atlas ichthyologique" no mention 

 whatever is made of this species, which is ranged amongst 

 the doubtful species by GtfNTHER and has been — with a 

 query — very briefly and insufficiently described by Kner 

 (Fische Novara Exp. 1865 — 1867, p. 324) from Ceylon. We are 

 at a loss which species was meant by Bleeker. Lesueur 

 has described a variety of his erytlirorJiynclius too (1. c.) and 

 this variety has been united by CUVIER & VALENCIENNES (Hist, 

 nat. Poissons XIX. 1846, p. 35) with H. diissumieri (not with 

 H. gainiardi as the authors themself state by mistake on p. 41). 

 It is thus possible that BLEEKER meant H. dussiuuieri by his 

 erythrorhynchus. 



We have examined, in the Vienna Museum, the specimens 

 mentioned above and described by Kner as H. erythror- 

 hynchusY^^ss,?.. They seem to us to belong to H. xanthopteriis C.V. 

 as described by Day. 



13. Hemirhamphus lucens C.V. 



Hemiramphus lucciis Cuvier & Valenciennes, Hist. nat. Poissons XIX. 1846, p. 62. 



Prof. Reinwardt observed in the Moluccos a species of 

 halfbeak, from which he communicated the following note to 

 Cuvier and Valenciennes, who called the species //. lucens. 



"Rostri apex singulari modo lucet sub aqua, nempe vesicu- 

 laris oleo fulvo repletus in eum exeunt vasa duo sanguifera 

 et nervi insignia per totam maxillam inferiorem decurrentia. 

 In vesicam quoque exit maxilla ipsa in sitas duas bifida. An 

 Esox brasiliensis}.W2.\y\'i.-A.\. in mari et in fluminibus vulgo: Julum 

 Julum Bodo". 



As no description of the fish is given, H. lucens is a 

 nomen nudum.
