Disk, including the ventrals, rhombic, longer than wide; anterior mar- 

 gins sinuous, posterior outline convex; tail moderate, depressed, with a 

 narrow cutaneous fold on each side; angle formed by snout less than 

 right. Rostral cartilage rather slender. Mouth moderate, much curved, 

 width 1| in distance from end of snout. Teeth small, cusps sharp, in 42 

 rows on the upper jaw (male adult). Eyes moderate; interorbital space 

 narrow, deeply concave, its width 3 times in the distance from the 

 end of the snout to the eye. Spiracles smaller than the eye. Ventrals 

 medium. Dorsals small, separated by a space with tubercles; a vertebral 

 series of small tubercles on back and tail ; 2 lateral series on each side 

 of tail; a series on each orbital ridge; a group of several above the end 

 of the rostral cartilage; a group on each pectoral opposite eye and spiracle; 

 a group of retractile spines opposite the shoulder near the outer angle of 

 the pectoral; the disk otherwise smooth above; lower side of snout with 

 fine, sharp scales or shagreen. Differing from B. eglanteria, which it resem- 

 bles in shape, in a somewhat shorter snout and in coloration. Disk, 

 including ventrals, 9.5 inches; width 9; tail from vent 9.6; total length 

 16.25 inches. Light yellowish brown, sprinkled with small spots of brown 

 intermixed with others of white; on base of each pectoral a little behind

Disk little broader than long, the anterior margins convex ; tip of snout 

 obtuse; snout not produced; width of mouth f its distance from tip of 

 snout; teeth in 44 series; entire upper surface rough with small asperities; 

 a median series of spines on back and tail, a lateral series on each side of 

 this on back and 2 on tail, a series on each orbital ridge; a single spine 

 on forehead between eyes, several above tip of snout; a group on hinder 

 angle of pectoral and on its front ; lower surface smooth. Tail a little 

 longer than disk. Light brownish, freckled with paler, marked with a few 

 groups of small darker spots ; several spots on the tail ; one at base of each
