single series, each jaw anteriorly with one pair of canines, the 

 lower pair received between the teeth of the upper ; no pos- 

 terior canine tooth ; dorsal spines subequal in height ; scales 

 large ; cheek with two series of large scales ; lower jaw not 

 produced backwards. (Ch. chlorurus, Bl. ; Ch. lunulatus, 

 Forsk. ; Ch. diagramma, Lacep. &c). 



21. Epibulus, Cuv. Nine dorsal spines; scales very large; 

 the lower jaw much produced backwards. (E. insidiator, 

 Pall.) 



**** Eight or nine dorsal spines ; head entirely naked or with only a 

 few very small scales, either on the cheek or on the operculum. 



22. Anampses, Cuv. Dorsal spines nine ; head entirely naked ; 

 scales of moderate size ; lateral line continuous ; each jaw with 

 two compressed teeth anteriorly, the lower of which are re- 

 ceived between the upper ones. (A. cceruleo-punctatus, Riipp. ; 

 A. geographicus, Cuv. & Val., &c.) 



23. Hemigymnus (Halichoeres, sp., Riipp. ; Tautoga, sp., Cuv. 

 & Val., Bleek.). Dorsal spines nine; opercles naked, cheek 

 with a strip of very small scales ; scales of moderate size ; 

 lateral line continuous; each jaw with two conical canines an- 

 teriorly, the lower of which are received between the upper 

 ones. (H. (Mullus) fasciatus, Thunb. ; H. (Labrus) melapte- 

 rus, Bl. ; H. notophthalrhus, Bleek. ; H. leucomos, Bleek., &c.) 



24. Stethojulis (Julis, sp., Cuv. & Val. ; Halichceres, sp., 

 Bleek.; Halichoeres, Kner). Dorsal spines nine; head en- 

 tirely naked ; scales rather large, those in the thoracic region 

 as large as, or larger than, those on the side of the body; 

 lateral line continuous ; a posterior canine tooth. (St. st?'i- 

 giventer, Benn.*; St. t rilineat a = Labrus trilineatus, part., Bl. 

 Schn. = Julis sebanus, Cuv. & Val. = Halichoeres Casturi, 

 Bleek.; St. albovittata= Labrus albovittatus, Bonnat. —Jidis 

 balteatus, Quoy & Gaim. ; St. interrupt a, Bleek. ; St. banda- 

 nensis, Bleek.) 



25. Halichoeres (Halichoeres, sp., Riipp., Bleek. ; Julis, sp., 

 Cuv. & Val., Kner, not Haliclwres, Kner). Dorsal spines 

 nine ; head entirely naked ; scales of moderate size, those in 

 the thoracic region smaller than those on the side of the body ; 

 lateral line continuous ; anterior teeth conical ; a posterior 

 canine tooth. (H. Dussumieri, Cuv. & Val. = J r . exornatus, 

 Richards. = H. notophthahnus, Bleek. ; H. hortulanus, Lacep. ; 

 H. melanurus, Bleek. ; H. miniatus, Kuhl & v. Hass. ; H. 

 Argus, Benn. ; H. Blcekeri, Gthr = J. Cuvieri, Bleek. ; H. Cali- 



* In all the eight specimens examined by me, the posterior canine tooth 

 is as distinct as in its congeners.
