LEPTOPHIDIUM MARMORATUM, Goodf. and Bean. (Figure 308.) 

 Leptophidium marmoratum, Goode and Bean, Proc 17. S. Nat. Mus., vn, 188. r >, 423. 



Body somewhat elongate, stoutish anteriorly, gradually tapering, its greatest height 

 (27 millimeters) 7^ in total length. 



Head thickish, its length (39 millimeters) 5 in total length. Intcrorbital area broad, 

 convex, its width nearly equal to length of snout, which is very slightly less than 5 in 

 head's length. Snout blunt, spineless. Eye circular, the diameter (10 millimeters) 4 in 

 head's length and somewhat exceeding the. length of the snout. Maxilla extends to the 

 vertical through the posterior margin of the orbit, the mandible far beyond, its length 

 equal to that of postorbital portion of head. Teeth on vomer and in the jaws in villiform 

 bands, the outer series in the latter slightly enlarged. Pseudobranchise present. Gill- 

 rakers short, 8 below angle of first arch, the longest less than one-half diameter of eye. 

 Branchiostegals 7. Ventrals with length (22 millimeters) as long as postorbital part of head. 



Dorsal origin at distance from snout (44 millimeters) contained 4A in total length, with 

 28 rays in a space equal to length of head, counting from the origin of the fin. 



Anal origin separated from snout by distance (76 millimeters) 2{j in total length. 



Length of pectoral (19 millimeters) 2 in head's length, or 10 in total. 



Scales closely imbricated, ornamented with delicate concentric, stria'. Lateral line 

 apparently complete, located about one-fourth distance from dorsal to ventral outline. 



Color, yellowish .may, marbled along the entire upper half of head ami body with olive 

 brown. Dorsal and anal tins with black margins. 



The type (Cat. No. 37237, U. S. X. M.), an individual L98 millimeters in length, was taken 

 by the Albatross from station 2350, in 23 10' 39" N. hit., 82° 20' 21" W. Ion., at a depth of 

 213 fathoms.

Dictionary, 361. 



Ophidioids with elongate compressed, tapering tail, vent antemedian, suborbitals 

 moderate, mouth inferior. One short anterior dorsal and no other; anal tin very long, con 

 fluent with caudal. Ventrals reduced to simple filaments, each of 2 rays, the inner of 

 which is rudimentary, inserted behind the symphysis of the clavicle. 



ATELEOPUS, Schlegel. 

 Ateleopus, Schlegel, Fauna Japonica, Poissons, 255. — Gotjther, /<»•. cil. ; Challenger Report, xxn. 159. 



Head with the snout much protruding and obtusely rounded, the cleft of the mouth 

 being at the lower side of the head : maxillaries protractile in a downward direction. Body 

 and tail compressed, elongate, naked. One short dorsal, the rudimentary second dorsal ot 

 the Macruridce having entirely disappeared; one long anal, continued on to the. caudal. 

 Ventral reduced to a filament which is composed internally of two rays, intimately con- 

 nected by a common membrane; this fin is inserted at the symphysis of the humeri. Teeth 

 in the jaws villiform, in bands; vomer and palatine bones smooth. (Gunther.\
