NO. 2133. FISHES TAKEN BY "ALBATROSS," 188S— THOMPSON. 465 



8. MENIDIA MAULIANA (Steindachner). 



Numerous specimens, the longest 145 mm. to tip of caudal rays, 

 from Tome and Lota, Chile, corresponding in all details to the 

 description given by Steindachner. The narrow lateral stripe and 

 greater depth distinguish it at once from other species. The gill 

 rakers are few, 3+13 or 14, thus having about half as many as are 

 present in Menidia regia. 



9. MENIDIA REGIA (Humboldt and Valenciennes). 



Atherina regia Humboldt and Valenciennes, Rec. Obs. Zool. Anat. Comp., 



1835, vol. 2, p. 187, Peru. 

 Atherina laticlavia Cuvier and Valenciennes. 

 Basilichthys microlepidota of Authors (not of Jenyns). 



Very numerous specimens, th-e largest 290 mm. in total length, 

 from Lota and Tome, Chile. The extrtmes of measurements in 

 hundredths of body lengths of 12 specimens are given in parentheses. 



Head 4| (0.22 to 0.24) in body length, 5* in total; depth 5§ 

 (0.17 to 0.20) in body, 6§ in total; eye 4 J to 5^ in head (0.04 to 

 0.06); snout 3 (0.07 to .08); width of lateral body band 4^ in body 

 depth (0.04 to 0.05); interorbital breadth 3^ in head (0.06); dis- 

 tance between dorsal insertions equal to depth of body (0.17 to 

 0.19); dorsal rays VI to VIII, I, 10 or 11; anal rays, I, 16 to 18 

 (usually I, 17); scales in lateral line 83 to 90, in transverse series 

 between insertions of first dorsal and of anal 16 or 17; gill rakers 

 8 + 25. 



MaxiUary extending to within half a pupil diameter of vertical 

 from anterior orbital edge; prcmaxillaries protractile; jaws of equal 

 strength and length; teeth in jaws in two rows, none on palatines or 

 tongue, occasional teeth on vomer; gill rakers two-thirds of eye 

 diameter in length; first dorsal set midway in total length; base of 

 anal extending slightly farther posteriorly than that of dorsal. 



Scales imbricated in normal fashion on dorsal surface of 'head; 

 anterior body scales nearly oval, without basal radii, circuli widely set; 

 posterior body scales nearly quadrangular, with four or five basal 

 radii; circuli close set and distinct; vertical fins scaleless; cheeks 

 scaled, four rows below eye, eight or nine between eye and posterior 

 opercular edge. 



Lateral silvery band broad, extending over two and a half rows of 

 scales. 



This species has been referred to Atherina regia Humboldt by 

 Giinther, whose example is here followed, as there is nothing in 

 the original descriptions which differentiates the two species lati- 

 clavia and regia.
