bulary teeth 18 or 19 on each side. Anterior nasal tubes 

 about one half the vertical diameter of the eye; gill open, 

 ings narrower than the eye ; eye about one half the 

 length of the snout, situated midway between the end of 

 the snout and the angle of the mouth, contained 2^ 

 times in the length of the head is Si times in the 

 length of the body; tail somewhat longer than the 

 body. Head and body encircled with about 20 ver- 

 tical black bands, as wide as the outerspaces between 

 them ; two pairs of these rings in distant parts of the 

 animal are united, each by a cross band, in one case 

 the cross band being superior, in the other inferior ; 

 the first ring is on the snout, the second through the 

 eye. 



This species is closely allied to Muroena rupellii 

 (Grthr. VIII, 104) but appears to differ from that spe- 

 cies in having one ring on the end of the snout, in the 

 width of the rings relative to the interspaces, and in 

 the smaller gill opening.

 of the snout ; it is contained 2f times in the length of 

 the snout. Gill openings nearly as wide as the eye.
