series fully as strong as those in jaws; both lips minutely fringed; 

 anterior nostril with a simple (undivided) tentacle behind a rather 

 prominent tube, the combined length of tube and tentacle equal to 

 two-thirds diameter of eye; 2 separate and distinct fringed tentacles 

 on upper margin of eye, the anterior one much the larger, about as 

 long as eye, the second one only a httle more than half length of eye; 

 dorsal fin beginning a little in advance of margin of preopercle, 

 moderately notched, the first soft ray being considerably longer than 

 the last spine, the spinous part not elevated, none of the spines bearing 

 membranous flaps, the third to fifth spines longest, about as long as 

 postorbital part of head, 1 .7 in head ; soft part of dorsal notably shorter 

 than spinous part, its longest rays fully as long as the longest spines; 

 caudal slightly attached to dorsal and anal, its margin rather strongly 

 convex, only about as long as postoribtal part of head; anal long, of

nearly uniform height throughout, its base 1.9 in length; ventral short, 

 the principal rays free only at tip, 1.7 in head; pectoral broad at base, 

 the longest rays in lower half of fin 1.4 in head, 5.6 in length. 



Color olivaceous-brown; head rather darker than body; back with 

 a series of 10 dark cross blotches, each enclosing a small light spot;

 indications of light dots present on back and side; a pale, horizontally 

 elongate area behind lower part of eye; a dark dot on posterior rim 

 of orbit; lower surface of head with dusky cross stripes; fins mostly 

 pale olivaceous; the dorsal with a black spot between the second and 

 third spines, and with dark cross bars extending on the fin above the 

 dark "saddles" on the back, definite anteriorly but becoming obscure

 where with dark markings, these most distinct along the base and

This apparently new species is represented in the collections by a

 caudal) long, seined at Lagunilla, Independencia Bay, by the Mission.
