The color is uniform deep crimson red throughout. The ventrals, dorsal, and anal being 

 margined externally with greyish black. The lips appear to have a much deeper, mayhap, 

 purple hue, as also the cephalic depressions above alluded to.

Family LAB RID AE, Bonap. 



The body is elongated and covered with scales, cycloid in structure, the lateral line being 

 either continuous or interrupted behind. There is but one dorsal fin anteriorly spinous, the 

 spines of which being mostly provided with a membranous flap at the posterior edge of their 

 upper extremity. Fleshy lips surround the jaws. The pharyngeal bones are provided with 

 blunt pavement-like teeth or transverse plates, and the union of the inferior pair takes place 

 without leaving any trace of its suture. The fourth- gill has but one branchial comb, and the 

 last branchial split behind it is wanting. The accessory gills or pseudo-branchiae are present. 

 The stomach has no cul-de-sac ; the pyloric appendages are wanting ; the air bladder is simple.

A species of this family was made known under the name of 



Lahrus pulcher, Ayres, in Proc. Cal. Acad. Nat. Sc. I, 1854, 1, 



but since no specimens were procured we can offer no description of tlie same.

The Atlantic species of this genus were never met with along the eastern shore of North 

 America, but they seem quite abundant in the warmer waters of the Caribbean sea.
