EUCROSSORIIIXrs DASYPOGON. 53 



ElTCROSSORHINUS. 



Eucrossorhinus Regan, 1908, Proc. Zool. soc. Lond , p. 357. 



Head broader and more depressed, eyes smaller, spiracles larger, and dermal 

 lobes around the head more numerous and more dissected than in the species of 

 Orectolobus. A series of branching dermal lobes below the lower jaws and a 

 nearly continuous series from the n'arial lobe to the base of the pectoral. Dorsals 

 smaller than the ventrals. Anal smaller than the dorsals, close to the sub- 

 caudal ; latter narrow, separated by a notch from the terminal. 



Probably a subgenus of Orectolobus. 



Eucrossorhinus dasypogon. 



Crossorhinus dasypogon Bleekeb, 1S67, Arch. Need., p. 400, pi. 21, f. 1. 

 Eucrossorhinus dasypogon Regan, 1908, Proc. Zool. soc. Lond., p. 357. 



Elongate, depressed in body and head; tail nearly half of the total length, 

 compressed posteriorly; snout short, broad. Eyes small. Spiracles large, two 

 or more times the length of the eyes. Nostrils at the end of the snout; anterior 

 valves with a long cirrus on one side of which there is a fold with several lobules; 

 posterior valves f orming a fold around the outer side of the nostril and continuing 

 backward into the fold of the upper lip and another along the side of the nasoral 

 groove and ending in a cirroid free extremity toward the angle of the mouth. 

 Between the narial lobe and that at the angle of the mouth there are about five 

 lobes, and between the angle of the mouth and the pectoral there are about 

 twenty more, of which six or eight are on the fold extending from the angle. 

 Sixteen or twenty more form a transverse series behind the lower lips. Pectorals 

 short, broad, rounded. Dorsals subequal, rounded ; origin of first dorsal above 

 the hindmost fourth of the base of the ventrals, base ending about its length 

 forward from the second dorsal. Anal much shorter than the dorsals, origin 

 behind the base of the second dorsal, narrowly separated from the subcaudal. 



Brown profusely marked with small spots of white ; a small spot of white 

 behind each spiracle; caudal region with four of five indefinite irregular trans- 

 verse areas of darker; lower surfaces light, plain. 



Bleeker's description and figure were drawn from two specimens, a male 

 of 220 mm. and a female of 800 mm., taken off Waigiu, Aru, New Guinea.
