11. Rhinobatus schlegeli Miiller & Henle. 
Formosa (Jordan & Eyermann). 
Family RAJID/. 
12. Raja hollandi sp. noy. (Plate LXIV.) 
Interorbital space 3% in distance from eye to tip of snout; width of mouth 12; 
length of first dorsal 14 times, caudal (upper Jobe) 1% times interorbital space ; 
length of eye nearly equal to interorbital space. 
Body rhomboid, broad, the width of the disk one-fourth greater than its length; 
head not large and snout not much produced, though ending in a small point; 
anterior margin of disk full (slightly convex) in front of and lateral to eyes, weakly 
concave in outer half; distance between eye and margin of disk twice interorbital 
space; mouth scarcely undulate, the angle made by meeting lower jaws about 75°- 
80°; teeth small, rounded, about forty-five rows in upper jaw: nostrils large, sepa- 
rated a distance about equal to width of mouth, their length (antero-posterior) about 
one-half width of mouth, with which nostrils are confluent; posterior margin of 
nasal flaps fringed ; interorbital space concave ; a supraorbital semi-cirelet of eight 
or ten short spines, directed backward ; spiracles a little wider than half length 
of eye, directly posterior to eye’s outer half; width of gill-opening about 25 in length 
of eye; body and head smooth except for the supraorbital spines and a single median 
dorsal spine a little farther behind eyes than their distance apart; back and sides 
of tail with five rows of short backwardly directed spines ; under edges of snout, to 
a point even with outermost gill-opening, beset with numerous minute spines. 
Dorsals separated a distance 14 times length of base of first dorsal; second 
dorsal separated from caudal a distance three-fifths length of base of first dorsal ; 
total length of tail from axilla of ventrals equal to seven-tenths width of disk ; 
angle of pectorals falling a little in front of midway of length of disk ; ventrals 
deeply notched, distance from ventral notch to posterior tip of ventral about four 
times in length of tail. 
Color in spirits brown above, lighter bluish to greenish beneath ; back and all 
upper surface except tail and snout densely covered with small black specks about 
the size of coffee grains; snout translucent, its upper surface appearing whitish in 
reflected light; the numerous mucus pores of under side of snout and sides of mouth 
each surrounded by a cirele of black ; tail brownish above (perhaps faintly mottled), 
paler with some dusky underneath.
