very wide, the membranes narrowly joined to isthmus on median line. No 

 lateral line. Branchiostegals 5. Dorsals separate, the first of 6 very 

 slender, flexible spines ; the second elongate, similar to the anal ; caudal 

 long and pointed, free from dorsal and anal; ventrals close together, 

 separate, each of 1 spine and 4 rays, their insertion below or behind peer 

 torals ; anal papilla present. A remarkable typo, belonging to the Oxyme- 

 topontinw, differing widely from our other Gobioid fishes. Gulf of Mexico, 

 in rather deep water. (i'oS, arrow; y\K)66a, tongue.) 



2515. IOGLOSSTJS CALLIURUS, Bean. 



Head 5 ; depth 7 to 7|. D. VI-22 to 24; A. 1, 21 to 23. Body very elon- 

 gate, slender, much compressed, of equal depth throughout; head com- 

 pressed, without osseous crest; mouth very oblique, the lower jaw 

 strongly projecting; premaxillaries in front on the level with pupil; 

 maxillary extending to opposite front of pupil, its length 2| in head; 

 upper jaw with a narrow band of about 2 series of conical cardiform 

 teeth, those of the outer row much larger than the others, behind these 

 2 small conical curved canines; lower jaw with a single row of smaller 

 teeth, behind which are about 4 short canines directed somewhat back- 

 ward ; the posterior pair strongly curved ; no teeth on vomer or palatines. 

 Tongue narrow, pointed. Eye large, nearly twice length of snout, 3 

 in head, its diameter considerably more than depth of cheek, about \ 

 more than interorbital width ; opercles unarmed. Pseudobranchise pres- 

 ent. Gill openings wide, extending forward below, the membranes 

 attached mesially to the very narrow isthmus, across which they do not 

 form a fold. Gill rakers long and slender. Dorsal fins separated by a 

 short interval, the first of very slender somewhat filamentous spines, the 

 longest about as long as head ; second dorsal little more than \ as high 

 as first, apparently nearly uniform, separated from the caudal by an 

 interval nearly length of head; caudal lanceolate, its middle rays 

 filamentous, about the length of rest of body; anal rather high, 

 similar to soft dorsal ; ventrals I, 4, inserted very slightly in advance of 

 base of pectorals, the 2 fins very close together, but apparently quite sepa- 

 rate and without basal fold of skin, the fin little longer than head, the 

 inner rays filamentous; pectoral with broad base, about \\ in head. 

 Anal papilla very short, midway between tip of snout and base of caudal. 

 Body with very small, nonimbricate, embedded scales, these a little larger 

 and imbricate on the tail; cheeks with embedded cycloid scales; scales 

 very weakly ctenoid, most of them appearing cycloid; no lateral line. 

 Color light olive, everywhere densely punctate ; dorsals edged with black ; 

 middle of caudal reddish, with paler bluish edgings. Length 4 inches. 

 Here described from specimens from off Pensacola. Gulf of Mexico ; known 

 only from the Snapper Banks off Pensacola, in rather deep water. (ua\Xo^ 

 beauty; ovpd, tail.)
