 eorrespondino- parts of Lampris and Jjitlgonla. The front border of 

 the canosteon is decurved backward in both, and the prc,))ortion.s of 

 the hypocoracoid and hypercoracoid do not differ very widely. The 

 actinostsof-.l;^/;rA>/r/V/, however, are comparatively free and the supra 

 scapula not forked. The pelvis is also quite different.

In fine, at present apparently no better position can ])e found for 

 Lampris than somewhere in the line of the Scombroidean supcrfaniily. 

 It even agrees with the Scombrids, Xiphiids, Coryphivnids, Carangid.s 

 and their relatives in the deep bifurcation of the roots of the caudal 

 rays which clamp the hypural and epural bones, and provisionally at 

 least it should be approximated to them. 



Dr. Boulenger has proved, however, that the Opah is not especially 

 related to the Scombroidea, and it is quite po.ssible that he may be 

 sustained in the isolation of the family Lamprididie a.s rt'presontative
