LEPIDORHOMBUS, Gunther. 



Lepichn-homhus, (sul)g. of Hhornhns), Gi'NTHER, Cat. Fish. Rrit. Mas., IV, 1862, 407, 411. 



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

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

 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; gill rakers well developed, lance- 

 olate. Branchiostegals 7. {Giinther.)

 Rhomhiis (Lepklorhnmbiis) ineyxsloma, Gunthkr, Cut. Fisli. ISiit. Mas., iv, 1862, 411. 



The 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 si>aL'e and the maxilhiry included); interorbital 

 space very narrow; the diameter of the eye is two-ninths the length <>f 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 2J^ in that of the head. Teeth in thojaws in a very narrow band, widening an- 

 teriorly. The h)wer eye is somewhat in advance of the upper. Tlie dorsal fin termi- 

 nates at a distance from the caudal which e(iuals the depth of the free portion of the tail; 

 its longest rays al-e 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. No spine 

 before the anal. 



Radial formula: B. 7; D. 85—87; A. 67— (ilt; L. lat. 12(<. Vert. 11-30. 



Color, yellowish brown. {Gnnthcr.) 



This form, occasioually found on the coasts of Great Britain and Scandinavia, was 

 taken by the French deep-sea explorers at various points ofi" the coasts of Spain : iid 

 Morocco and the Azores, at depths of 60 to 560 meters (stations XVii (1880); viii (ls82); 

 II; IV; V; vi; xvii; cxxili). Out of 29 specimens, 24 were from inside the 100-fathom 

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