LEPIDORHOMBUS, Gunther. 

 Lejiidiirhotnbun, (siilij;. of Rhombus), Gi'iNTHEK, Cut. Fish. Brit. Maa., IV, 1862, 407, 411. 



Sinistral ijleuronectoids witli moutli wide, tlie length of the maxillary being more than 

 one-third of that of the head. Each jaw with a narrow baud of villiform teeth, withcmt 

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

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

 ciliated. Gill membranes scarcely united at tlic throat; gill rakers well developed, lance- 

 olate. Branchiostegals 7. ((liiutltfr.)

188K, 188. 

 Rhombus (Lepidoi-hombiis) meijasloma, (juNTHER, Cat. Fish. Brit. Mas., l\', 1862, 411. 



The height of the body is coiitained 2| in the total length (witliont caudal), tlie length 

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

 ing nearly the whole liead (the iutenn-bital S])ace and the maxillary included); iuterorbital 

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

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

 circular curve al)ove the pectoral. Lower Jaw prominent; the length of the maxillary is 

 contained 2;^ in tbat of the head. Teetli in the jaws in a veiy narrow band, widening an- 

 teriorly. The lower eye is somewhat in advance of the upi)er. The dorsal tin termi- 

 nates at a distance from the caudal which e<|uals t\w dc|)th of the lice portion of the tail; 

 its longest rays are at the commencement of tlie i)osterior third of the lin, where they are 

 two-fifths of the length of the head, and somewhat shorter than the jieetoral. No spine 

 before the anal. 



Kadial formula: B. 7; D. 85—87; A. 07— fi9: L. lat. 120. Vert. 1 l-.W. 



Color, yellowish brown. [Giintlirr.) 



This form, occasionally found on the coasts of (Ir.-at Britain and Sc'andinavia, was 

 taken by the French deep sea exjtlorers at vaiions points off the coasts of Spain : ad 

 Moroccoaudthe Azores, at depths of 00 to 500 meters (stations xvii (1880); \ iii (1.>.S2); 

 II; IV; V; VI; xvii; cxxiii). Out of 29 specimens, 21 were from inside the 100 fathom 

 line— those from the Azores (560 meters) and off Morocco (550 meters) the deepest.
