NOTES ON ROME AUSTRALIAN PIPE-FISHES. 31 



Body with seven distinct but smooth ridges, the abdominal one being very prominent. The 

 latero-superior pair terminate at the hinder base of the dorsal fin. The medio-lateral ridges ex- 

 tend backward to the last body ring, and terminate beneath the anterior ends of the upper cau- 

 dal edges. The latero-inferior body ridges join the lower caudal edges. The body is much 

 deeper than wide, its greatest depth being somewhat before the dorsal fin; the back is slightly 

 convex so that the base of the dorsal is elevated. 



Snout short and thick The median elevated ridge commences on the upper lip, and ex- 

 tends back to above the middle of the eye; it is thin and flexible, and its upper margin is en- 

 tire and slightly concave. A low smooth ridge defines the lower margin of the snout on either 

 side. Xostrils close together near the eye, the anterior tubular. Top of head and nape with a 

 very low ridge which is lost on the first body ring. Operculum with fine radiating striae. 



Dorsal fin placed above five body rings, and two tail rings. Pectoral and caudal well de- 

 veloped ; a minute anal fin is also present. 



Colour. — Rich orange brown, with numerous dark edged, blue ocelli 



Described from an adult female 235 mm. long, which is deposited in the Tasmanian 

 Museum. 



Locality — Dredged in eleven fathoms in Thouin or Wineglass Bay on the east coast of 

 Tasmania ; 13th April, 1014. Collected by Mr. E. A. Briggs, after whom the species is named.

I have examined the type of this species in the Macleay Museum, and have little doubt that 

 it is generally identical with //. briggsii. It is in very bad condition, being largely decayed, and 

 the anterior half of the head and the abdomen are entirely lost. So far as can be ascertained, 

 it agrees with Macleay 's description in all but one detail; instead of the upper edge of the 

 body passing that of the tail by one ring as described, they really overlap on two and a half rings. 

 The medio-lateral ridge and the upper caudal edge terminate on the same ring, the latter be- 

 ing over the other. Length from posterior margin of operculum to vent 40 mm. ; vent to base of 

 caudal fin S7 l A mm. 



Locality. — West Australia.
