named Vicente Leonardo, who took it in a gill-net oli" Santa Catalhia 

 Island. It i)roved to be a species of the genus CcphaloscylUuvi Gill, 

 and apparently identical with the type of the genus {ScijUium laticeps 

 Dumeril). This species has been hitherto recorded, so far as we know, 

 only from Tasmania. 



The following is a description of our specimen (Xo. , 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 ojienings 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 



2r+27" 



First dorsal beginning over middle of ventrals ; second dorsal begin- 

 ning behind front of anal and ending a little before end of anal ; base of 

 pectorals low and horizontal, the last two gill openings above them. 

 Oaudiil fln 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 cross-shaped figure ; middle i)art 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 si)ecimens of 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 sta'.ement not hard to believe. 



A fisherman at Santa Barbara, ]\Ir. A. Larco, tells me that he also 

 knows this shark. He has in his possession two egg-cases, with the 

 eggs, 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.
