Head to hind spiracle edge 714 i'^ total length. Snout li/o in head 

 to hind spiracle edge as seen above meets at broadly obtuse angle; 

 eye 5, 3 in snout, 2i/^ in interorbital ; mouth width 3 in head to first 

 gill opening; teeth lozenge-shaped, close-set in oblique series, each 

 with cusp over its long axis; upper buccal flap fringed with about 

 21 points ; 2 fairly large buccal papillae with rounded but somewhat 

 frayed edges; interorbital 2 in head to hind spiracle edge. Spiracle 

 close behind eye, little larger than eye. 



Head, back, median line of tail to root of caudal spine evenly cov- 

 ered with thorny granules, which largest near median line, not form- 

 ing median row or differing amongst themselves except in size. 

 Similar minute granules over snout and on sides of pectorals. Scat- 

 tered prickles stud long tail, smaller and disappearing before tip. 

 Ventrals, under surface of disk, sides and lower surface of tail 

 basally, smooth. 



Tail filamentous (spine removed), without folds; pectorals form 

 subcircular disk, width slightly less than its length, which li/o in 

 tail, outer angles widely rounded, hind edges convex and hind angles 

 obtusely rounded; ventrals slightly longer than interorbital width. 



Brown, lighter below. Margins of ventral surface smoky brown. 

 At least 9 ill-defined, crescentic, brownish markings arched along 

 middle of each pectoral, largely faded. Length, 865 mm. (Wliitley.) 



East Indies, Melanesia. The above is largely from Whitley's 

 redescription and figure of Macleay's holotype of Trygon granulafa. 

 He also describes and figures a smaller one 751 mm. long from the 

 Santa Cruz Group with "no ocelli" and therefore evidently with- 

 out the crescentic markings on the pectorals in the holotype.
