Body oblong, compressed. Snout pointed. Mouth large. Lateral 

 teeth uniserial, coalesccnt at base. Canines f anteriorly; hind 

 canine each side. Preopercle usually finely serrated. Scales 30 to 

 35 in lateral line. Cheeks and opercles with imbricated scales. 

 Dorsals and anals, also caudal, scaled basally. Lateral line com- 

 plete. Dorsal spines 12, rays 10. Anal spines 3, rays 12. 



Indo-Pacific. Tropical shore or reef fishes, brilliant, of moderate 

 or large size. 



In this connection we have examined the type of Lepidaplois 

 mirahilis Snyder (Proc. U. S. Nat. Mus., vol. 35, 1909, p. 96, Riu 

 Kiu; idem, vol. 42, 1912, p. 506, pi. 66, fig. 1). It is Cat. No. 62234, 

 U. S. N. M., and 190 mm. long. We believe it represents a subgenus 

 allied with the subgenus Lepidaplois. 



LIENARDELLA, new subgenus 



Type. — Lepidaplois mirahilis Snyder.^* 



Head blunt, with rather abrupt snout, so the muzzle not protrud- 

 ing. Scales on head large, about 5 rows on cheek and none on 

 preopercle flange. Body with dark and light alternating transverse 

 bands.

 Mauritius.)
