longest ray is t-qual in lengtli to the base of tiie tin, which is as long as the snout: 

 pectoral as long as the snout : caudal tin a little longer than the pectoral : a minute 

 anal fin. 



Described from an example 97 mm. in length, one of two female specimens 

 collected by Mr. Rumball at Kangaroo Is. in 1901 ; the other measures 102 mm. 



Colours. Head brown, finely marked with white. Body light brown, with 

 five large white spots on the back between the nape and the origin of the dorsal 

 fin : similar, but less distinct spots on the caudal : dark brown bands encircle the 

 body at about every fourth ring throughout the length ; on the trunk the lightei' 

 interspaces are mottled with white.

 sub-dorsal annuli 3-44-5-6: brood annuli 19-23 4-0. 



Head 2 -o to 2 -3 in the trunk and 3 '3 to 6 'O in the total length : snout i '4 

 in the head: eye 7-1 in the snout and 10 o in the head. Trunk 2 '3 in the length. 



.Snout very long, four times as long as the post-orbital portion of the head, 

 compressed but not deej): a ruflimentary crest and very feeble supraorbital 

 ridges : snout with reticulating raised lines ; rest of head and body uniformly 

 granular : opercles with additional radiating striae but no median keel. Indica- 

 tion of a nuchal ridge. Body a little wider than deep : ventral surface wider than 

 tliat of the dorsal: trunk longer than the tail. Ridges moderately well defined: 

 upper ridge continued on to the fifth caudal scute, below the origin of the ridge, 

 which commences on the side and attains the dorsal profile at the sixth ring: lower 

 ridge continuous. Caudal fin rather large and long, the median rays longest, 

 nearly as long as the snout: a minute anal fin. Longest example 360 mm., 

 dredged by Sir Joseph \'erco in Spencer Gulf. Also taken in St. Vincent Gulf
