NO. 1896. NEW PHILIPPINE PEDICULATE FISHES— RADCLIFFE. 211 



in total length), elongate, margin rounded; anal 3.54, its insertion 

 under or slightly beliind posterior base of dorsal; ventrals 2.93; 

 pectorals 1.85, reaching nearly to caudal. 



Color in alcoliol: Dusky olivaceous; caudal margined with blackish 

 above and below, basal portion of median rays wliite, becoming 

 sepia distally; other fins brownisli black. 



Type.— Qui. No. 70273, U.S.N.M., 9 cm. in length, taken with a 

 beam trawl at station 5660 (lat. 5° 36' 30" S.; long. 120° 49' 00" E.), 

 in Flores Sea, off the coast of Celebes, at a depth of 692 fathoms,' on a 

 bottom of gray mud and sand. 



From D. nasutus (pi. 22, fig. 3; pi. 23, fig. 3) this species difTers 

 in having the disk narrower, much more elevated and heavier, and 

 the framework much less cartilaginous. 



DIBRANCHUS SIMULUS Smith and Radcliffe, new species, 

 riate 22, fig. 1; plate 23, fig. 1. 



Dorsal 6; caudal 9; anal 4; ventral 5; pectoral 15. 



Head not as broad as long, elliptical; disk rather strongly arched, 

 length measured to anterior margin of gill-opening 1.58, breadth 1.71, 

 depth 2.56 in its length; body, exclusive of caudal, 2.71, rather 

 short; eye 5.82, lateral; snout 4.55; mouth large, jaws subequal; 

 teeth on jaws villiform; palate and tongue edentulous; maxillarj^ 

 3.72; nostrils conspicuous, on anterior margin of rostrum, a tliin 

 membranous arch separating the two apertures; interorbital 3.28, 

 broad, slightly arched; rostrum moderate, projecting beyond jaws, 

 the anterior margin bent downward until the tentacular aperture is 

 barely equal to diameter of eye, its height being about one-half its 

 mdth; the tentacular cavity extending backward nearly to middle of 

 eye; from its posterior base springs the illicium, wdiich is projected 

 forward, reacliing the tentacular aperture, tip trilobate, each lobe 

 composed of a mass of spongy filaments; tubercles stellate, rela- 

 tively small, unequal, each capped with a long slender spine; tuber- 

 cles on rostrum, sides of disk and body not so well developed as in 

 related species; spines on rostrum and at angles of disk obsolete; 

 ventral surface of disk naked, except for a few small tubercles in 

 axil of pectoral; tubercles on dorsal surface of body small, widely 

 separated, a distinct naked area around gill-aperture; gills two. 



Fins well developed; insertion of dorsal midway between anterior 

 margin of eye and tip of caudal, longest ray 3.42; caudal 1.95, distal 

 margin truncate; base of anal entirely behind base of dorsal, longest 

 ray 3.72; ventrals 3.16, well developed; pectorals 2.05, tips reacliing 

 lialf way between posterior base of anal and base of caudal. 



Color in alcohol: Ligiit olivaceous; ventral surface wliito, waslied 

 with vinaceous buff; anal, ventral and lower base of pectoral, wliite;
