2716. AUCHENOPTERUS MONOPHTHALMUS, GUnther. 



Head 3*; depth 4. D. III-XXVI, 1; A. II, 18; scales 2-32-9; eye 5 in 

 head; maxillary 1}; pectoral Ik; caudal 1^. Body compressed, deepest 

 at middle of pectorals; head moderately pointed, the upper profile 

 slightly and ovenly convex; mouth large, maxillary reaching past eye; 

 jaws subequal; teeth villiform, in bands on jaws, vomer, and palatines; 

 interorbital space ilat, as wide as eye; a multifid dermal flap over poste- 

 rior edge of eye, and a smaller one on each side of nape; head naked; 

 body with rather large, regular scales; fins naked. Origin of dorsal over 

 edge of preopercle, the first 3 spines separated from rest of fin by a rather 

 deep notch, the membrane from third spine joining fourth spine at about 

 its middle; spines of posterior part of dorsal the highest; front of anal 

 midway between tip of snout and base of caudal, tips of last rays reach- 

 ing slightly beyond base of caudal and tips of last dorsal rays; pectorals 

 reaching front of anal ; ventrals long and slender, inserted in front of base 

 of pectorals a distance equal to 1^ eye ; caudal rounded. Color light gray- 

 ish red or brown, with about 6 cross bars of darker brown, running up on 

 dorsal; between the bars are scattered milky white irregular spots; a 

 black spot, ocellated with white, on front of dorsal, a similar spot near 

 posterior end, sometimes duplicated ; narrow cross bars on anal; a dark 

 bar on base of caudal, and a dark blotch on base of pectoral. Here 

 described from specimens, a couple of inches in length, from La Paz, Lower 

 California. Gulf of California to Panama, abundant in rock pools, creep- 

 ing about among Corallina; close to A. hitegripinuis, but the first dorsal 

 higher and more separate from rest of fin. {/toyog, one; 6(l>6aXjit6?, eye,
