beginning well before gill opening at end of second third of head; 

 lower jaw with a few large pores. 



Light brown, everywhere closel}' marbled with dark brown, above 

 and below, the dark streaks confluent; head largely dark brown; gill 

 opening a little darker. 



One specimen 12i inches long, Type No. 6481, Leland Stanford 

 Junior University Museum, taken at Okinawa, in the northern Riu 

 Kin by Yonekichi Komeyama. The species is nQxn-er Ech/dn<i ddicatula 

 Kaup, but both trunk and tail are proportionateh" longer. The dorsal 

 in E. aniUyodon is inserted farther back. 



It is named for Professor Kishinouye, of the Imperial Fisheries

This genus contains those mora3^s which have the fins altogether 

 wanting or developed only at the tip of the tail; the teeth are small, 

 pointed, subequal, the mouth of moderate size, and the anterior nos- 

 trils only provided with a tube. The typical species have the tail 

 about as long as the rest of the body, but the single Japanese species 

 agrees with the related genus ('iKinnomunena in the extreme short- 

 ness of the tail. The typical species have tubes on the anterior nos- 

 trils only. These, by some error, were indicated by Jordan and Ever- 

 mann as forming a distinct subgenus, Sci/tiea, but Scutica is an exact 

 sj^nonym of UropteTyghiH. The species having tubes on the posterior 

 nostrils should have been set apart from the others. For this group, 

 the type ))eing Icldl^yophix. tlgt'lnuif Lesson, we ma\' suggest the new 

 generic n^me, Scndicaria. Mur(Enohlenmi., used for this group by 

 Kaup, is not available, as its orignal type was a 2fy.r!ne. {ovpa. tail;
