tail about a snout's length shorter than rest of body. Color dark brown, 

 with small, round, yellow spots, smaller than pupil, like pin points, scat- 

 tered evenly and sparsely over the body ; spots with blackish margins; 

 lower jaw mottled. Pacific coast of Mexico, the two known specimens 

 from Rio Grande, Costa Rica, and from Cape San Lucas. Copo says of 

 his specimen that the anal fin is a little more than one-third the total 

 length, which is not true of the one here described, {nocturnuii, nocturnal, 

 black.)

 ScuUca, Jordan & Evermann, new subgenus, {neclurus). 



This genus contains several species of small Morays, distinguished by 

 the apparent alisence of fins. The teeth are small, pointed, and subequal, 

 and the cleft of mouth of moderate size. In spite of its simplicity of 

 structure, it is not by any means a primitive type, but a further degener- 

 ation from the form of Li/cudontis and Minana. Our species (with U. 

 tigrinis) differs from the type of Ufoptert/tjiua in having only the anterior 

 nostrils tubular. This may define a new subgenus, Scutica {scitiica, a 

 whip), (oi'yja, tail ; rrrf^vf, fin.)
