PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM. AL 
named Vicente Leonardo, who took it in a gill-net off Santa Catalina 
Island. It proved to be aspecies of the genus Cephaloscyliium Gill, 
and apparently identical with the type of the genus (Scylliwm laticeps 
Duméril). This species has been hitherto recorded, so far as we know, 
only from Tasmania. 
The following is a description of our specimen (No. ———, United 
States National Museum): 
Head short and broad, broader than long, and not half as deep as 
broad; snout very blunt, not projecting much beyond the mouth ; eyes 
oblong, small, the spiracles behind them well developed ; no nictitating 
membrane ; nasal openings not confluent, their flaps separated by a broad 
space, the breadth of which is two-thirds the length of the snout; nasal 
flaps conspicuous, without cirrus; mouth very broad, not strongly 
curved, with only a trace of labial fold at the angle; skin at the angle 
of the mouth thin, smooth, pale, and raised into little cross-folds. 
Teeth similar in both jaws, small, sharp, with a long central cusp and 
a small basal cusp on each side. About four series of teeth. Teeth 
30 + 30 
a 
First dorsal beginning over middle of ventrals ; second dorsal begin- 
ning behind front of anal and ending alittle before end of anal; base of 
pectorals low and horizontal, the last two gill openings above them. 
Caudal fin short. 
Color dark grayish-brown, with five pairs of dark bars across the back, 
their form irregular; the central pair bounded by straight lines and 
forming a eross-shaped figure; middle part of each fin blackish ; entire 
surface of body and fins covered with round black spots of different 
sizes, these larger and less numerous on the belly; on the sides are also 
whitish spots, smaller and less numerous than the black ones. 
This specimen was a female, with the ova nearly ripe. The stomach 
when received by us was much inflated. The intestines contained num- 
erous specimens ef a small gasteropod shell. 
Other fishermen about Wilmington tell me that they take this shark 
occasionally, about two or three times a year, and that when fully 
inflated it is half as broad as long, a statement not hard to believe. 
A fisherman at Santa Barbara, Mr. A. Larco, tells me that he also 
knows this shark. He has in his possession two egg-cases, with the 
eges, which he says were taken from one of this species. These egg- 
cases are ‘“wheel-barrow shaped,” like the egg-cases of rays, and pro- 
vided with long tendrils.
