specimen agreeing well with the detailed accounts of Cuvier & Valen- 

 ciennes (ix, 11) and of Day (Fishes of Gt. Brit. 1881, 124, pi. xliv). 

 There are at least three well-defined species or varieties of the type 

 called Trachurus represented in our collections. These appear to cor- 

 respond to the three species described, but not named, by Cuvier & 

 Valenciennes (ix, p. 17), and all three are, if descriptions are to be 

 trusted, found in the Mediterranean, and pretty widely distributed over 

 the globe. 



Tlie following characters are shown by our specimens : 



a. Body comparatively deep and compressed, the depth 4 to 4 J- iu length ; scutes 34 



to 36 -j- 36 to 38 in number, the anterior scutes scarcely lower than the posterior, 



their height about f diameter of ej'e; length of curve of lateral line 1? to 1| in 



the straight part ; maxillary reaching past front of pupil 2J to 2^ iu head ; lining 



of opercle blackish Trachurus.* 



aa. Body moderately compressed, the depth 4^ to 4f in length ; scutes 38 to 404-38 to 

 42 in number, the anterior little lower than the posterior, their height about three- 

 fifths diameter of eye; curve of lateral line IJ to li in straight part ; maxillary 

 reaching to front of pupil, 2| in head ; lining of opercle scarcely blackish.

 (New Holland). Trachurus trachurus in part, of various writers, and apparently the 

 most abundant type in the Mediterranean. We are unable to disentangle its synonymy 

 entirely from that of the preceding into which it may perhaps be found to intergrade. 

 We have collected numerous speci-mens of this type at Genoa and at Venice. A 

 specimen collected by Mr. Xautus at Cape San Lucas is iu the National Museum.
