diameter of e3"e behind base of pectoral; origin of anal l)elow tenth 

 dorsal spine; both fins united with the caudal, but their tips reaching 

 to the end of second third of the length of caudal, and not as described 

 and tigured by Messrs. Jordan and Snyder. The caudal hn of the 

 American specimen (see iig. 1) conveys the impression that it has been 

 broken on the tip and restored by the artist. 



Skin thick and loose, in irregular folds, covered with thumb tack-like 

 plates which make it rough; a l)road longitudinal band on the side in 

 the middle between dorsal and anal smoother. These plates cover 

 also the outer side of basal parts of pectoral tins; caudal not convex

posteriorly, the posterior margin of the fin completeh' truncate; pec- 

 torals as described by Messrs. Jordan and Snyder. Disk oval, with 

 thin margins; its longitudinal diameter contained 2| times in the length 

 of head. The distance of the anal opening from the hind margin of 

 the disk is equal to the width of the mouth. Color graj'-yellowish, 

 clouded with darker gray and l)hickish on the dorsal side; margin of 

 the hind part of dorsal, caudal tin. and anal with ])ase of them black- 

 ish; pectoral dark gi'ay, on the inner or posterior side blackish. 



1 believe that all of these slight discrepancies noted al)ove do not 

 indicate specitic difference, and that my specimen belongs to the species 

 Liparh or Trismegistus owstonL
