160 MEMOIRS OF THE CARNEGIE MUSEUM 
As noticed by Jordan and Evermann, the fauna of Taiwan bears close relation 
to that of Southern China, and also to that of Southern Japan. In the main, how- 
ever, the fauna is tropical, a large proportion of the species being found in India 
and the Philippines. The coral-reef species of Formosa are still unknown, except 
as recorded from the Riu Kiu Islands, which lie to the northward. Few of the 
species of Central Japan extend their range southward to Taiwan. 
Family SCYLLIORHINID &. 
1. Cephaloscyllium umbratile Jordan & Fowler. 
One specimen from Takao, measuring tio feet to end of tail. 
2. Pristiurus sauteri sp. nov. (Plate LXIII, Fig. 1.) 
30dy not so slender as that of Pristiwrus eastmani of Japan; head measured to 
first gill-opening 6 in total length; depth equal to half distance between tip of 
snout and fourth gill-opening ; snout 2% in head; front and back edge of each nos- 
tril with a pointed flap; these crossing and closing the nostril at middle; entire 
width of one nostril equal to the internarial space and almost éxactly twice the 
distance of the inner angle of nostril from mouth ; width of mouth slightly greater 
than length of snout and about equal to interorbital space; teeth each with a 
median long cusp, on either side of which is a cusp of about half its length ;. each 
short cusp may or may not have at its base one or two rudimentary cusps; roof of 
mouth and tip of tongue with minute prickles; spiracles directly behind eye and 
distant slightly less than their diameter from it; distance from first to fifth gill- 
opening equal to distance from spiracle to first opening. 
Scales minute, each with a strong central cusp, on each side of which is a rudi- 
ment, and with an evident median keel; upper edge of tail with a low keel being- 
ning a little less than two eye-lengths behind second dorsal and extending backward 
to merge into upper lobe of caudal fin; this keel armed on each side with a row of 
enlarged scales, between which are four rows of ordinary scales. 
First dorsal originating over back of base of ventrals, its base reaching nearly 
an eye-length farther back than base of ventrals; origin of second dorsal a little 
behind middle of base of anal; second dorsal only a little, but distinctly, smaller 
than first ; free edges of both dorsals nearly straight; caudal with a shallow notch 
on under side near tip; width of ventral base equal to distance in front of eye to 
middle of spiracle ; inner distance between bases of pectorals equal to length of eye ; 
free margin of pectorals straight or slightly concave ; tip of anal a little short of a 
vertical from tip of second dorsal.
