 streaks of ground color; head nearly pale below, save some dark on chin 

 and isthmus; two wide streaks from eye across cheek; opercle dark 

 brown; top of head with the color of body; lips with brown and pale 

 stripes; posterior half of maxillary pale; dorsal rather dark; caudal 

 uniform gray or faintly barred ; anal similar to dorsal in color; the rays 

 with pale tips forming a white edge; pectoral like caudal; ventrals pale. 

 Length about 1.5 inches. 



A plainly marked species most closely related to N. lugtibris (Poey). 

 Puerto Rico; only 3 specimens known, all from the coral reefs about 

 Culebra Island, February 9, 1899. 



(Named for the type locality.)

Head 3.6; depth 3.7; eye 3.5; snout 3.4; maxillary 4.5 ; mandible 4.5; 

 interorbital 4; scales 3-45-5. D. xxu, 11; A. u, 20; pectoral 1 in head; 

 ventral 1.2; caudal 1.2; longest dorsal spine 1.5, ray 1.2; longest anal 

 ray 1.5. 



Body short, rather stout, compressed; head short, snout short, but 

 pointed; mouth rather small, little oblique, the gape scarcely reaching 

 orbit; teeth in each jaw in a single series; gill membranes broadly united 

 across the isthmus; eye small, iuterorbital space wide; dorsal outline 

 rising abruptly to above eye, thence gently curved to origin of dorsal tin. 

 and from there nearly straight to base of caudal fin ; ventral outline regu- 

 larly convex. 



Color in alcohol : Light olivaceous, the body crossed by about 9 or 10 

 broad dark vertical bars, which extend upon dorsal fin, these usually 

 broadest above, the pale interspaces therefore broadest on lower half of 

 body; the fourth from last is a narrow dark line, the one following it is a 

 double spot, the next narrow and indistinct, the last, at base of caudal, 

 more distinct, followed by 3 small irregular white spots; top of head 

 brown ; side of head with fine punctulations ; a dark line running forward 

 from eye, a dark spot below eye, 2 or 3 dark blotches on anterior edge of 

 opercle; under surface of head crossed by 3 or 4 irregular, indistinct dark 

 lines; caudal and anal with fine dusky punctulations; pectoral and ven- 

 trals pale. 



This species is close to M. yilln, from which it may be distinguished by 

 the larger dorsal and anal fins, the greater depth, wider interorbital, and 

 the coloration. 



Puerto Rico; known only from the type, 1.4 inches long, obtained by 

 the U. S. Fish Commission expedition to Puerto Rico, February 11, 1899. 



(Named for Dr. H. F. Moore, naturalist on the U. S. Fish Commission 

 steamer Albatross.)
