Snout short, broadly rounded. Nostrils nearer to the mouth than to the 

 end of the snout. Anterior nasal valves reaching the mouth in a broad flap in 

 which they are narrowly separated at their point of attachment in front of the 

 symphyses of the jaws; a very rudimentary cirrus on each valve. Posterior 

 nasal valve a narrow short cirroid. A shallow nasoral groove. Mouth wide, 

 much curved; upper lips concealing the lower at the angles; a labial fold at 

 the angles, on the lower jaw, extending half way to the symphysis. Eyes 

 moderate; edge of lower lid closing within the upper. Spiracle small, near the 

 corner of the eye. Gill openings small, hindmost two above the base of the 

 pectoral. Dorsals small; origin of the first dorsal a short distance farther back 

 than the ends of the bases of the ventrals; second dorsal smaller, origin above 

 the hindmost fourth of the base of the anal. Base of the anal one and two thirds 

 times as long as that of the first dorsal; tip of the fin ending below the middle 

 of the base of the second dorsal or farther back. Ventrals very oblique, those of 

 the male joined above the claspers and more produced. The base of the anal is 

 longer than its distance from the caudal and it subtends one fourth to one half 

 of the forward portion of the base of the second dorsal. 



Light rusty or reddish brown thickly sprinkled with small spots of brown, 

 smaller than the eye to mere dots, on back and flanks, larger and more widely 

 scattered on the fins and on the lower flanks. 



Among the specimens examined, males of eighteen inches were immature, 

 and those of about two feet in length appeared to be quite mature and had 

 claspers fully developed. In the small variety usually confused with this, C. 

 duhamelii, described below, the male is mature at a length of thirteen inches. 



Mediterranean and Atlantic; off the coasts of Europe.
