Family SCYLIORHINIDAE' 



Cat Sharks 



Characters. Two (rarely only one) dorsal fins, the ist much shorter than the caudal, 

 at least y-i of its base posterior to origin of pelvicsj caudal much less than V2 of total 

 length, not lunate in form, its lower anterior corner not expanded as a definite lobe, its 

 axis but little raised 5 caudal peduncle not greatly flattened dorso-ventrally or expanded 

 laterally; sides of trunk anterior to anal without longitudinal ridges; no precaudal pits, 

 at least in most species; inner margins of pelvics more or less united posterior to cloaca; 

 snout not greatly elongate or jaws widely protrusible; 5th, or 4th and 5th, gill open- 

 ings over origin of pectoral; gill arches without rakers and not interconnected by a sieve 

 of modified denticles; nostril not connected with mouth by a groove, or if so connected, 

 its anterior margin does not bear a well developed fleshy barbel; no nictitating membrane 

 within lower eyelid, but there may be a well developed longitudinal fold below the latter; 

 spiracles present; labial furrows more or less developed; teeth small, numerous, with 

 several cusps, and several rows functional; head of normal shape, not widely expanded 

 laterally; rostral cartilages 3, united at dp; radials of pectoral mostly on metapterygium ; 



I. We include White's (Bull. Amer. Mus. nat. Hist., 74, 1937: 107, 108) Halaeluridae and Atelomycteridae under 

 the Sc^-liorhinidae, the differences in vertebral calcification on which they were based not seeming sharply enough 

 alternative to warrant the rank of families.
