CENTS LXX. C.\R \\XOUORUS. 



One dorsal fin ; no ipurions fins ; upper lip fixed. 

 This genus is nearly allied to the preceding, and con- 

 tains 4 species, formerly included in the genus Scomber. 



GENTS LXXI. Casio. 



One dorsal fin ; upper lip extensile. 



The species contained in this genus are two in num- 

 ber ; and might with propriety have been united with 

 those in the preceding genus. The first is termed C. 

 rxnilescens, and is a native of the Molucca isles ; and 

 the second, C. equulus, was described by Forskael. 



GENUS LXXII. C.SIO*ORUS. 



One dorsal fin ; no lateral ridge ; separate spines in 

 front of the dorsal fin. 



This genus is nearly allied to the preceding, and con* 

 tains 2 specie* described from the MSS. of Commerson. 



GENIS LXXIII. Com-.. 



Covering of the head entire ; one dorsal fin; the 1st or 

 3d rays of the ventral fins twice as long as the others. 



Naturalist* are indebted to Commerson for a know. 

 ledge of the two species which compose this genus. 

 These he termed C. aygula and C. angulatus. 



GENUS LXXIV. GOMPIIOSIS. 



Snout produced, in form of a nail ; head destitute of 

 scales like those of the back. 



Commerson likewise instituted this genu, consisting 

 f two species- the G. czruleus and O. varius. 



La Cepede instituted this genus. The name is from Classifica- 

 T>(Tjr, peclen, and p /%?, rostrum. There is but one tion of 

 species observed by him in the Dutch collection. Fishes. ^ 



GENUS LXXXI. POGONIAS. 



One dorsal fin ; chin bearded. 



This genus, from *-/>, tart a, was instituted by 

 La Cepede for the reception of one species, the P. fas- 

 ciatus, in the collection of the Stadtholder at the Hague. 



GENCS LXXXII. BOSTHYCHUS. 



Body long ; serpentine ; two dorsal fins ; two tenta- 

 cula on the upper jaw. 



The two species of which the genus consists are but 

 imperfectly known. They rest on the authority of Chi. 

 nese drawings. 



GENTS LXXXIII. BOSTRYCHOIDES. 

 One dorsal fin. In other respects like the preceding. 

 A Chinese drawing of the only species of this genus 

 was found in the Dutch collection. 



GEN-US LXXXIV. ECHENEIS. Sucking Fish. 



Head depressed, and furnished with an organ of ad- Sucking 

 hesion, consisting of an oval plate with transverse folds, fch. 



The name of the genus is derived from t%u, habeo, 

 and , natit ; because the best known species was 

 supposed to have the property of sticking to ships, and 

 retarding their motions. It is the remora of the ancients.

 I ommersc 



L otnmerson formed this genus, which contain* two 

 species, one of which is the Cha-todon unicornis of 

 Gmelin, found in the Red Sea by Forskael, and at the 

 Isle of France by Commerson. 



GENUS LXXXV. MACROUHUS. 

 Two dorsal fins ; tail twice as long as the body. 

 This genus was instituted by Blocn for the reception 

 of the Cory phirna rupestris of Linnaeus, which is found 



extremity of the tail ; skin on the coasts of Greenland and Iceland. To the inha- 

 bitants of these countries it furnishes a plentiful supply 

 of nourishing food. In some of the districts where it 

 is found it is called berg-lax, or rock salmon. It is the 

 ingnumusct of the Greenlanders. 



A horn or protuberance on the snout ; two plates or 

 each side of the 



Genus I. XXVI. KTPHOSUS. 



Bark elevated ; a hunch on the shoulder ; gill lid 

 with scales like the body. 



This Commenonian genus contains one species, the 

 K. bigibbo*. 



GEKCS LXXVII. OSFHRONEML-S. 



Ventral fins, each of five or six ray*, the first spinous, 

 and the second tcrmii at-d by a long filament. 



This gran* contain* two species. 1 he first of these, 

 O. gonuny. i an inhabitant of the frc-h waters of Hm- 

 dostan and China. It has been naturalised in toe Isle 

 of France, and ought to be translated to Europe. As 

 food, it i< said to be of exquisite flavour. The second 

 is the O. gallus, the Scaurut gallus of Forskael. It fre- 

 quents the coasts of Arabia, and is contidered by the 

 inhabitants as a noxious species. 



Ocmw LXXVI1I. 



Ventral fins with one ray longer than the body ; one 

 dorsal fin. 



The genns contains two species. One of these is the 

 Labrns trichopteras of Gmelin, a native of the Indian 

 seas. The other is T. mentum, described from a draw- 

 ing by Commerson. 



GEMVS LXX IX. MOKODACTYLUS. 

 Ventral fins of one short ray. One dorsal fin. 

 The M. falciform!* was first observed by Commerson, 

 and is the only species of the genus. 



SH LXXX- PLECTROHINCHUf. 



Lips plaited and marginated ; one or more of the 

 of the gill-lid denticulated. 



GENIS LXXXVI. CORYPH^VA. 



Head truncated, or very obtuse ; one dorsal fin, near- 

 ly as long as the body and tail. 



This genus contains sixteen species, which La Cepede 

 has distributed into sections, from the shape of the tail. 

 The first species which La Cepede describes is the C. 

 hipptirus, which is found both in the Atlantic and Paci- 

 fic ocean. Its flesh is very agreeable ; and being a vo- 

 racious fish, easily taken, and fond of following vessels, 

 often furnishes the sailor with a grateful repast. When 

 taken out of the water, the beautiful combinations of 

 colours fade as the fish expires, and the dying cory- 

 phene is contemplated by sailors with as much delight 

 as the ancient Romans are said to have exhibited on 

 viewing similar changes in the expiring mullet, when 

 brought to the table before the fi-.r t began. 



GEN-US LXXXVII. HF.MM'TF.IIONOTI;?. 



Head truncated ; one dorsal fin, about half the length 

 of body and tail. 



La Cepede formed this grnus from two species for- 

 merly included in the genus C'oryphaena. The H. quin- 

 que-maculatut of La Cepede, the (.'oryphtcna penladaclyla 

 of other writers, inhabits the rivers of China, the Mo- 

 lucca isles, and other places in the Indian Archipelago. 

 It is gregarious, appearing in vast shoals, and is eager- 

 ly sought after as an article of food. It is dried or salted, 

 and forms an article of trade in those countries similar 

 to the cod fishery of our northern districts. 



GENl'S LXXXVIII. CORYPIIENOIDES. 



Head truncated, or very obtuse ; one dorsal fin ; gill 

 opening a simple transverse slit. 



This genus contains only one species, the C. branchie-
