 partly luiiled. but lire from the istliiniis bcliiiid. (iill r;ikers iiiiiiute, 

 tubercular, in moderate Mumbcr. A single loug dorsal lin consisting of 

 spines only. The spines longest in the posterior i»ortion; anal fin lower 

 than the dorsal, but similar in shape. Pectoral large, entirely below 

 median line. V^entrals well develo])ed, in advance of i)ectorals; caudal 

 rounded, distinct. Intestinal canal short, with five sniall pyloric ececa.

The greatest depth of the body, 1 inch, is contained 5^ times in 

 the total length without caudal. The length of the head — Inj inches 

 — is one-fourth of the total withont caudal. The diameter of the eye 

 is one-fiftli of the length of the head. The snout is acute. The ante- 

 rior nostril is tubular and nearer to the eye than to the tip of the snout. 

 The posterior nostril is close to the ui)per anterior margin of the eye. 

 The maxilla extends almost to the vertical through the hind margin of 

 the eye. The intermaxilla is long and slender and reaches nearly as 

 far back as the maxilla. The intermaxillary teeth are in broad bands, 

 with an outer series of 5 or large canines, those near the symphysis 

 largest. The teeth in the mandible are in broad bands in front, fol- 

 lowed by several enlarged canine-like teeth. A large canine on each 

 side of the symphysis, the interspace between the two mandibulary 

 canines receiving the canines of the intermaxilla when the jaws are 

 closed. A row of 8 iiores along the ramus of the mandible and the edge 

 of the preopercle; another series around the lower margin of the pre- 

 orbital bone as described for the genus. About 8 gill rakers on the 

 first arch below the angle. 



The distance of the dorsal origin from the snout is nearly equal to 

 the length of the head. The spines are lowest in front; the longest 

 spine is two-sevenths of the length of the head. The longest rays of the 

 anal are near the end of the fin and scarcely exceed the length of the 

 eye. The length of the pectoral cipials that of the i)ostorbital part of 

 the head. The ventrals are close together; the inner rays longest — 

 two-sevenths as long as the head. The caudal is rounded, its length 

 nearly one-half that of the head. The vent is under the eleventh spine 

 of the dorsal. 



The upper lateral liiu^ begins above and slightly in advance of the 

 upper angle of the gill opening, curves veiy slightly over the ])ectoraI 

 and extends to below the twenty-fifth spine of the dorsal, its distance 

 from the dorsal edge equal to the diameter of the eye and also equal to 

 its distance from the lower lateral line. The lower lateral line begins 

 nnd<'rthe sixteenth spine of the dorsal and extends to the caudal. On 

 each side of the abdominal ridge, between the ventrals and the vent,
