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.F. 



1 . Cephaloscyllium umbratile Jordan & Fowler. 



One specimen from Takao, measuring two feet to end of tail. 



2. Pristiurus sauteri sp. nov. (Plate LXI1I, Fig. 1.) 



Body not so slender as that of Pristiurus 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 25 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 exactly 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.
