ELOPIFORM FISHES 



30 mm 



Fig. 84. Albula vulpes (Linnaeus). Entire skeleton, scales omitted. 



scales which extends from the occiput to just behind the dorsal fin. The general 

 body squamation consists of thin cycloid scales, more or less square in shape, with 

 three to four basal radii and four to five basal lobes. The posterior edge of the 

 exposed field is often broken due to the thinness of the scale. The surface of the 

 scale is marked only by circuli. 



The modified scale row in the mid-dorsal line consists of oval scales, whose length 

 considerably exceeds their width. The bases of all fins are covered by scales. 

 Axillary scales are present at the bases of the pectoral and pelvic fins. Bone cells 

 are present in the scales.

Diagnosis (emended). Albula in which the preorbital part of the neurocranium 

 is equal to half the total neurocranial length. Quadrate/mandibular articulation in 

 advance of the level of the lateral ethmoid. Parasphenoid teeth of the same size 

 throughout the toothed area. Depth of the neurocranium at the autosphenotic 

 approximately 35 per cent of the neurocranial length. Opercular bone twice as 

 deep as wide. Ornamentation in the form of coarse rugosities present on the lateral 

 edges of the frontals above the orbit and on the quadrate.
