widely separated, besides front valve hind edge also with lobe of skin. 

 Gill openings graduated smaller posteriorly, last 2 over pectoral base. 



Scales very rough, especially on back where prickles large; on 

 under surface of tail not enlarged ; row of isolated large scales arises 

 on each side of occipital region and extends to second dorsal. 



First dorsal inserted little behind midlength over middle of ven- 

 trals, front edge 1% in head ; front edge of second dorsal 2% ; anal 

 little larger and opposite second dorsal, front edge 2%; caudal 3% 

 in rest of body, subcaudal little higher than anal; pectoral equals 

 head to second gill opening, width II/2 its length ; ventral length ly^ 

 in head to first gill opening. 



Brown above, white below. Upper parts with black transverse 

 blotches disposed alternately wider and narrower; wide bands on 

 occiput, predorsal, below both dorsals and one at base and another 

 towards middle of caudal lobe. Black mark below eye, another 

 below occipital patch and connected with first narrow band, others 

 along sides of body. In j^oung patches occur also on ventrals and 

 on anal and lower caudal lobe, but all markings become confused 

 with age and tend to break up into spots. Length, 1,010 mm.

South Australia, Tasmania, New Zealand, Chatham Island. "Waite 

 says : "When taken from the net the carpet-sharks were of relatively 

 enormous girth, due to the inflation of the stomach with water. 

 When the abdomen was pierced with a penlaiife blade a jet of water 

 spurted out to a distance of several feet, due to the elasticity of the 

 stomach. This inflation is common to members of the genus, and the 

 American and Japanese species are described as inflating their stom- 

 achs with air, when they float belly upwards."
