PLATE 81. 
Stingaree, 
Head 3 in body, measured from tip of snout to base of ventrals 
behind; depth about 444; snout 2 in head; eye 4%; width of 
mouth 214; internasal space 3; bony interorbital region 2; inter- 
spiracle region 1°/,;; space between anterior pair of gill-openings | 
1°/,; space between posterior pair of gill-openings 224; space 
between origins of ventrals about 174; greatest width of ven- 
tral 2'%%; length of ventral 124; caudal spine to its posterior 
attachment 124; base of dorsal fin 4; length of disk from tip 
of snout to tips of ventrals posteriorly about 134 in its greatest 
width; tail, measured from point opposite posterior edges of 
ventrals, 1%. Disk very broad. Head thick, depressed, 
broadly convex above. Snout flexible, compressed to lateral 
trenchant edge ending in a slight fleshy tubercle at top, and as 
viewed from above broadly convex. Eyes large, elongate, lat- 
eral, at some distance in advance of spiracles, with lower can- 
thus well developed, high and about midway in length of head. 
Mouth transverse below, dental edge slightly undulate or double- 
concave with depression in middle. ‘Teeth broad as usual, each 
median lamina very elongate. Lips thick and fleshy, upper 
broadly free and with rather narrow fringed margin. Lower 
lip thick, adnate, and with many plice. Nostrils large, within 
width of mouth and sending back a deep groove which curves 
around each side or corner of mouth though soon lost posteriorly. 
Interorbital space broad, flattened, or with a rather shallow 
median depression. Gill-openings rather small. Spiracles large, 
lateral and deep. Body perfectly smooth. Dorsal fin small, its 
edges rather evenly convex from origin which falls just behind 
posterior edges of ventrals, and much longer than high. Tail 
long and filamentous, cylindrical. Caudal spine longer than 
space between spiracles, depressed, and each edge antrorsely ser-
