NOTES ON MYCTOPHINE FISHES — PARR 



The type of M. imitator (suborbitale) is in every respect per- 

 fectly concordant with the brief preliminary diagnosis of M. simMe 

 rendered by Taaning, 1928 (p. 56), and, if the identity of the two 

 should become definitely established by further investigation of the 

 latter form, Taaning's name would have priority over the name 

 of M. hnitator. 



MYCTOPHUM PTEROTUM Alcock, 1891 



Scopelus (Myctophum) pterotus Axcock, 1891. 



Myctophum pterotum Fowlbe, 1928; Parr, 1928 (full discussion of earlier 



synonymy). 

 Myctophum gilberti Evermann and Seale 1907. 



Material investigated. Type specimen of Mycotophum gilheHi 

 Evermann and Seale, No. 55900, U.S.N.M. Philippine Islands. 



The identity of M. gilherti with M. pterotiom Alcock, already sug- 

 gested by Gilbert, 1913 (p. 81), could only be confirmed by an in- 

 spection of the type specimen of the former species.

 MYCTOPHUM FIBULATUM Gilbert and Cramer, 1897 



Myctophum fibulatum Parr, 1928 (with full discussion of earlier snyonymy, 

 p. 67). 



Material investigated. Type specimen No. 47711, U.S.N.M. 

 Hawaii. 



A fairly accurate illustration of the type of this species has been 

 rendered with the original description (Gilbert and Cramer, 1897 

 p. 411, and pi. 38, fig. 2 ^), and the species has been further discussed 

 in considerable detail by Gilbert 1913 (p. 81, under the headhig of 

 M. pterotwn Alcock) . 



The type specimen differs somewhat from the specimens previously 

 described and figured by the author (Parr, 1928, p. 67 and fig". 7) 

 in having the PLO very close to the lateral line, and by having the 

 last Pre immediately below, not directly in the end of the lateral 



'The legend (pi. S8, fig. 1) erroneously refers this figure to Diaplvus ch^-ysorhynchus, 

 which is shown in figure 3 on the same plate and is referred to the ahove-discussed species.
