ADDITIONS TO THE FISH FAUNA OF LORD HOWE ISLAND — WAITE. 37 



Hyporuamphus, sp. 



For the present I leave a small Hyporhampus undeteraiined. It 

 diffars markedly from //. intermedius, Cantor, and //. regularis, 

 Giinther, of the mainland, the former of which has been recorded 

 from the island. Both these species are referable to the genus 

 Ilyporhamphus, distinguishable from Hemirliamiihus by the 

 anterior position of the ventral tin. 



Upeneus pleurostigma, Bennett. 

 (Plate V.) 



This species was originally described by Bennett' in 1831, and 

 in 1859 Giinther" placed it as doubtfully synonymous with the 

 later described Upeneus brandesii of Bleeker.'^ In 1873-5, how- 

 ever, he confirmed his suspicions, as indicated by unreservedly 

 placing the last-named as a synonym of Bennett's species.^ 



The next step is not quite so clear to me. The Mullidaj are 

 contained in the last part of Bleeker's unfinished "Atlas." Of 

 this part (Vol. i.x ) we possess the plates, but not the text (of which 

 I understand eighty pages were issued). 



Bleeker publishes a figure under the name Parupeneus pleuro- 

 sligma, Blkr.,'' having apparently accepted Giinther's ruling as to 

 the specific identity of U. ple^irosiigma with U. brandesii, but in 

 changing the generic name added, as was his custom, his own to 

 the species. Since then the matter does not appeared to have 

 been referred to. A comparison of this figure with the descrip- 

 tions of U. pleurostigma by Bennett and Giinther shows that the 

 two cannot possibly be reconciled. 



By the kind services of Mr. Farnell, the Trustees have received 

 from Lord Howe Island a very fine example which I unhesitat- 

 ingly pronounce to be U. pleurostigma, Bennett. With the 

 material at my command, and having neither of the descriptions 

 of Bleeker, I am disposed to regard his illustration as of U. 

 brandesii, which is really a good and very distinct species. 



U. pleurostig7na has not therefore been illustrated, and I have 

 pleasure in publishing the accompanying figure of the Lord 

 Howe Island example (Plate v.) This specimen exhibits the 

 following characters : —
