LEPIDORHOMBUS, Gunther. 



Lepidorhomlus, (subg. of Rhombus), GtiNTHER, Cat. Fish. Brit. Mhs.. iv, 1SH2. 407, 411. 



Sinistral pleoronectoids with mouth wide, the length of the maxillary being more than 

 one-third of that of the head. Bach jaw with a narrow band of villiform teeth, without 

 canines; vomerine teeth; none on the palatines. The dorsal tin commences on the snout ; 

 nearly all the dorsal and the anal rays branched. Ventral free from anal; scales small and 

 ciliated. Gill membranes scarcely united at the throat; gillrakers well developed, lance- 

 olate, lirauchiostegals 7. {Gunther.) 



LEPIDORHOMBUS MEGASTOMA, (Donovan), Gi nther. 



Pleuronecies megastoma, Donovan, British Fishes, in, 51. — Vaillant, Exp. Sri. Travailleur et Talisman. 



1888, 188. 

 Rhombus (Lepidorhombus) megastoma, GOnther, ('at. Fish. Brit. Mus.. i\. Isiil'. 111. 



Tin- height of the body is contained 2^ in the total length (without caudal), the length 

 of the head 3i. Scales rather small, with the posterior margin ciliated and rounded, cover- 

 ing nearly the whole head (the interorbital space and the maxillary included); interorbital 

 space very narrow; the diameter of the eye is two ninths the length of the head. Each 

 fin ray is accompanied by a series of minute rough scales. Lateral line with a sub semi- 

 circular curve above the pectoral. Lower jaw prominent; the length of the maxillary is 

 contained 2$ in that of the head. Teeth in the jaws in a very narrow baud, widening an- 

 teriorly. The lower eye is somewhat in advance of the upper. The dorsal tin termi- 

 nates at a distance from the caudal which equals the depth of the tree portion of the tail; 

 its longest rays are at the commencement of the posterior third of the fin, where they are 

 two-fifths of the length of the head, and somewhat shorter than the pectoral. Xo spine 

 before the anal. 



Radial formula: B. 7: 1). 85—87; A. 07— 69; L. hit. 120. Vert. 11-30. 



Color, yellowish brown. (Giintker.) 



This form, occasionally found on the coasts of Greal Britain and Scandinavia, was 

 taken by the French deep-sea explorers at various points off the coasts of Spain tid 

 Morocco and the Azores, at depths of 60 to 560 meters (stations xvn (1880); vrn(lS82); 

 ii; IV; V; VI; xvu; cxxui). Out of 29 specimens. 24 were from inside the 100 fathom 

 line — those from the Azores (560 meters) and off .Morocco (5.10 meters) the deepest.
