Urolophos bucculentus Macleay. (Plate xli.. fig. 1-3). 

 Sandy-backed Stingaree. 



Urolophus bucculentus, Macleay, Proc. Linn. Soe. N.S. Wales, ix., 1885, p. 17:2; 



McCullooli, Binl. Res. Endeavour, iv., 4, 1916. p. 177. 

 Trygonoptera bucculenta, Waitc. Mem. Austr. Mus., iv., 1, 1899, p. 44, PL v. 



Breadth of the disc 0.4 greater than its length from the end of the snout 

 to the end of the pectoral fins. Tail, measured from its end to the middle of the 

 vent, 1.4 in the length from the same point to the end of the snout, and slightly 

 shorter than its distance from the mouth. Intcrotular and interspiraclo widths 

 subequal, 1.4 in the preocular portion of the head. Interna.sal width 2, and 

 width of mouth 2.1 in the preoral length. 



Breadth of the disc much greater than its length from the end of the snout 

 to the tip of the ventral fins. Snout imperfect — forming a sharp and sligiitly 

 projecting angle in the type. Anterior pectoral margins almost straight, the 

 outer angles rounded ; posterior-lateral margins convex, their junction with the 

 inner margins rounded. Eyes pi-ominent, rather large, their length less than 

 lialf the intcroculai- width. Intero-superior margin of the spiracle almost straight 

 without any ang-ular projection. Nostrils without free lobes posteriorly and 

 separated by a wide space from the angle of tlie mouth. Posterior margin of 

 the int<>rnasal valve minutely lobulate but not fringed; the postero-external 

 angles form lobes which lie in gi-ooves outside the lips. Teeth uniformly tesscl- 

 late in the female. A fimliriated velum behind the upper teeth, and a row of 

 about sixteen pajjillae behind the lower teeth some of which are paired. 



Tail depressed, with a well developed fold on each side extending' backward 

 to the origin of the spine; its width at the base is slightly less than that of the 

 mouth. The spine is inserted at the middle of its length, and in front of its 

 base is a well developed dorsal fin. Caudal fin large and rather narrow; it 

 originates below the hinder third of the spine on the upper surface, and extends 

 forward as a ridge to beneath the anterior third below. 



Colour. — Light pinkish tan above, the posterior portions of tiic pectorals 

 and ventrals ligliter. Whitish spots and short lines are distributed over the 

 back and greater ]iortion of the disc, but the snout and a broad pectoral margin 

 are unmarked; the spots are very small and close together on the outer portion 

 of their area but become larger interiorly and change info short vermiculating 

 lines on the branchial regions and back. Ventral fins with small white spots. 

 Tail with one median and two supero-lateral light stripes; the lateral folds 

 whil<>. Vertebral region of the caudal fin wliite marbled. 



Described and figured from a female examiile (iOO mm. wide. The snout, 

 end of the caudal fin, and portion of the ventrals being damaged in this 

 specimen, these details have been completed from the types. 



Identity. — The cotypes of this species have been skinned and are in a very 

 imperfect state of preservation. But a comparison of them with the specimen 

 described and figured leaves no doubt that the hitter is correctly identified.
