TELE OS I' EI 



Family Sillaginidae. With a toothed palate, but a separate spinous 

 dorsal and elongate soft dorsal aud anal. 

 Sillago, Cuv. ; Indo-Pacific. 



Incertae sedis. 



Family Anomalopidae. Two genera of deep-sea Perciform fish may 

 be provisionally placed here ; their osteology is still unknown. They 

 are remarkable for the possession of a large movable phosphorescent 

 organ below the eye ; it can be turned outwards when lit up and in use, 

 and turned back into the orbit when extinguished. 



Anomalops, Kner (Heterophthalmus, Bleeker) ; Photoblepharon, Weber ; 

 S. Pacific.

 Psettus argenteus, I.. (From Gunther.) 



Sub-Tribe A. II. With a subocular lamina. The body tends to 

 acquire a very flattened rhombic shape, with the elongated dorsal and 

 anal fins along the hinder edges. The pelvics become vestigial. The 

 mouth becomes very protractile, and the teeth very small, villiform. 



Family Scorpididae. The post-temporal is normal. 



Aipichthys, Stein. ; Cretaceous, Europe (?). Scorpis, C. and Y. ; 

 Atypichthys, Gthr. ; Atyposoma, Blgr. ; Psettus, Com. (Fig. 440) — Indo- 

 Pacific. 



Family Caproidae. The post-temporal is fused to the skull. The 

 mouth is very protractile. They clearly approach the Chaetodontidae in 

 structure, and perhaps should be placed in the next sub-tribe.
