the peculiar scales, the shorter soft dorsal and anal, the 

 oesopliageal papillse not toothed, and the pelvis quite separate 

 from the pectoral arch. This suggests that the loose attach- 

 ment of the pelvis in the Stromateidge may be a primitive 

 feature, a conclusion strengthened by the fact that they are 

 among the i^w spiny-rayed fishes known to occur in the 

 Cretaceous, the genera Platycormus and IIomoHoma having 

 been referred by Dr. Smith Woodward, apparently with good 

 reason, to this family. The Icosteidse have been generally 

 regarded as allied to the Stromateidge ; and in Icosteus, the 

 only genus I have been able to examine, the pelvic bones do 

 not even approach the pectoral arch, the ventrals being truly 

 abdominal notwithstanding their rather anterior position.

 of the antenna} and the femora, tibiae, and tarsi of all the legs 

 ferruginous, the apical two joints of the tarsi more or less 

 shaded with fuscous ; wings brownish hyaline, iridescent in 

 certain lights, with in the fore wing two obscure darker 

 brown bars, one along the basal and subbasal nervures, the 

 other spreading from the radial into third cubital and third 

 discoidal cells. Head wider than the thorax, the clypeus 

 very convex, its anterior margin rounded ; antennae filiform, 

 planted low down just above the base of the clypeus; front 

 very flat ; the eyes lateral, reaching down to the base of the 

 mandibles, their inner orbits parallel ; vertex broad, lightly 

 convex, passing by a gradual curve into tlie occiput. Thorax 

 short, the pronotum rounded anteriorly ; the mesonotum, 

 scutellum, and postscutellum very convex, the latter two 

 prominent ; median segment rounded posteriorly, with a 

 gradual slope to the apex ; legs very long and slender, the 

 posterior tibiae minutely spiued. Wings ample, the basal
