260 ACANTHOPTERYGII. 



Genus II. — Crenilabrus, Cuvier. 



Coricus, Cuvier ; Cyncedus, sp. Swainson. 



Branchiostegals five or six : pseudobranchim present. Body oblong and compressed. 

 Preopercle serrated. Teeth in the jaws conical and in a single row without any 

 posterior canine : palate edentulous. A single dorsal fin consisting of upwards of 

 20 rays, of which from 13 to 18 at least are spinous, and none are elongated : 

 anal with three spines. Scales of moderate size but not so many as forty rows : 

 those on the cheelcs and opercles being imbricate. Lateral-line continuous. 



A rather weighty objection exists to this genus, in that many of the young 

 of genus Labrus have the preopercle serrated, while in some of Crenilabri the 

 preopercle loses its serrature, so that they are similar to Labrus. Bleeker, 

 however, pointed out that no examples of this genus have so many as 40 rows 

 of scales along the lateral-line, whereas all of Labrus have more that 40. Until 

 the intermediate forms are recognized perhaps the validity of the genus may be 

 admitted. Bleeker restricted Coricus to some species, in which the snout is 

 produced. 



Geographical distribution. — Similar, to that observed in the genus Labrus. 



M. Gerbe (Rev. et Mag. Zool. xvi, pp. 255, 273, 337) has recorded how 

 species of this genus, G. massa and G. melops, form nests of sea- weed, shells, and 

 other substances in which the ova are deposited : both sexes engage in their 

 construction. G. pavo acts similarly (Moreau, 1. c), as do also species of the 

 genus Labrus (see page 255).
