ACANTIIOPTERYGIANS. 163 



Others again, have a crescent-shaped or bifurcated tail*. 



Anampses, Cuv., 



Have all the characters of a Girdle, with the exception of two flat teeth 

 in the jaws, which project from the mouth, and curve outwards. 



But one or two species are known; from the Indian Ocean j-. 



Crenilabrus, Cuv., 



Which we separate from the Lutjanus of Bloch, in order to arrange them 

 in their proper place, have all the characters, external and internal, of a 

 true Labrus, and only differ in the dentation of the border of their pre- 

 operculum. 



Some of them are taken in the northern seas; such as the Lut- 

 janus rupestris, Bl. 250; fawn-coloured, with clouded, blackish ver- 

 tical bands. Lutjanus norvegicus, Id. 256; brownish, irregularly 

 spotted and marbled with deep brown. Labrus melops ; orange, 

 spotted with blue; a black spot behind the eye; pi. xxi, f. 1. Za- 

 brus exoletus, or L. palloni, Risso ; remarkable for the five spines of 

 its anal £. 



The Mediterranean produces a great number which are decorated 

 with the most beautiful colours; the most splendid is the Labrus 

 lapina, Forsk. ; silvery, with three broad longitudinal bands formed 

 of vermillion dots, yellow pectorals, the ventrals blue, &c.§ They 



de Lacepede, established by that naturalist from the drawings of Commerson, have 

 turned out to be fishes of the present genus with truncated tails, the artist having 

 neglected to express the separation of the operculum from the preoperculum. The 

 Coris angule, III, iv, 2, appears to be the Labrus malapterus ; and the Coris aigrette, 

 III, iv, 1, must be closely allied to the Girelle Gaymard. M. de Lacepede has also 

 named Hologymnoses some of these fishes, in which the scales of the body, smaller 

 than usual, are concealed during life by a thick epidermis; but the scales which do 

 not appear in the drawing of Commerson, engraved Lacep. Ill, pi. 1, f. 3, are very 

 visible in the dried specimen deposited in the Museum; that genus must therefore be 

 included in Julis, together with the Demi-Disque, III, pi. vi, £ 1; the Annele, lb. pi. 

 xxviii, and the Cercle, which at least are closely allied to it. 



* Species with crescent-shaped or forked tails; Labre hebru'ique, Lacep. Ill, xxix, 

 3; — Labrus bifasciatus, Bl. 2S3; — L. lunaris, L., Gron. Mus. II, vi, 2, cop. Encycl. 

 196; — L. lunaris, Bl. 281, which is different, and may possibly be nothing more than 

 an altered Julis turcica; — L. viridis, Bl. 282; — L. brasiliensis, Bl. 280; — Julis coeru- 

 leocephalus, Cuv., or Girelle Duperrey, Voy. Freycin. Zool.pl. f. 333; — L. argente, 

 Lac. Ill, xviii. N. B. The Scarus gallus, Forsk., is probably the same as the Lab. 

 lunaris. 



f Labrus tetrodon, Bl. Schn. 263; — Anampses Cuvieri, Quoy and Gaym. Voy. 

 Freycin. Zool. pi. Iv, f. 1. 



X Add, Lab. gibbus, Penn. xlvi, copied Encycl. 403; — Lutj. virescens, Bl. 254, 1. 



§ Risso describes several in his first edition under the name of Lutjanus; in the 

 second he adopts our genus Crenilabrus, and carries the number of species to 

 twenty-eight; but all his species are not distinct, and his synonymes are sometimes 

 uncertain. His species should be compared with those of Brunnich, Bloch, iS:c. 

 The Lab. venoms, Brunn.; — L.fuscus, Brunn.; — L. unimaculatus, Brunn.; — Lutjanus 

 roslratus, Bl. 254, 2, perhaps the Cr. tinea, Risso; — Lab. 5-maculatus, Bl. 291, 2, is 

 the Crenil. Roissal, Risso; — Lutj. bidens, Bl. 251, 1; — Lab. mediterraneus, Brunn.; — 

 Lab: rubens, Brunn.; — Lab. perca, Brunn.; — Lab. spalatcnsis, Br.; — Lab. tinea, 

 Brunn.; — Lab. ocellatus, Forsk., or olivaceus, Brunn., &c.
