64 MEMOIES OF THE QUEENSLAND MUSEUM. 



Scales ctenoid above and below except on the lower surface of the head, where 

 they are cycloid ; the upper surfaces of the fin-rays are scaly, but the lower are naked 

 in the type. All the upper portion of the head, except the lips and anterior half of 

 the snout, is scaly ; the naked portion is separated from the rest by a fold of skin 

 which crosses the snout and is connected with the anterior dorsal ray : lower surface 

 of head naked anteriorly, with scattered cirri. Eyes small and round, the upper 

 partly in advance of the lower ; interorbital space scaly. Upper anterior nostril 

 with a tentacle which does not reach back to the anterior margin of the lower eye, 

 and which has a minute, inferior, secondary lobe at its base ; posterior nostril opening 

 into a short tube placed near the lip in front of the eye. A band of microscopic teeth 

 on the left side of each jaw. Mouth opening backward to the anterior margin of the 

 lower eye ; lips not fringed. 



Fins imperfect in the type. Dorsal commencing in advance of the upper eye ; 

 its rays increase in length backward, the posterior ones being almost as long as those 

 of the caudal. Anal similar to the dorsal. Caudal incomplete. The ventrals are 

 much damaged, and partly wanting ; they were evidently opposite each other and 

 subequal anteriorly, and separated from the anal by a short interspace. Pectorals 

 rhinute, the left a little larger than the right. Lateral line straight from the middle 

 caudal rays to the back of the head ; it is arched vipward and forward on the upper 

 surface of the head. 



Colour. — Uniform greyish brown after long preservation. 



Described from the t3rpe of the species which was lent me for the purpose by 

 Dr. R. Hamlyn- Harris, Director of the Queensland Museum. It is in very bad condi- 

 tion, and its fins are so damaged that the details of their structure cannot now be 

 determined, but enough is left to show that they are not altogether in accordance with 

 Ogilby's description. The left pectoral is longer instead of shorter than the right. 

 The ventrals are so imperfect that their form and extent cannot be made out, but 

 the anterior rays of each are present and are close together and subequal ; the second 

 ray of the left fin is also present, and well developed, so that the fin camiot be described 

 as " atrophied." Some of the dorsal and anal rays are missing, and those remaining 

 are so shrivelled that I am unable to measure them satisfactorily ; the outhnes of these 

 fins in the accompanying figure may therefore not be correct. 



Loc. — Rockhampton, Queensland.

 Greatest depth, measured on the lower surface, 2-8 in the length to the base of the 

 caudal rays ; head 5-1 in the same. Eye 7-2 in the head, and less than the interocular 

 space, which is 6 in the head. Pectoral fins 2-8, median dorsal rays 2-6, and median 

 ventral raj^s 2-6 in the head. 



Scales ctenoid above and below, and extending onto the fin-rays on both 

 surfaces. Upper surface of head scaly to the tip of the snout : lower surface with 

 fringes of cirri on the anterior third which extend backward near the lower border, 

 while smaller cirri define a series of mucous canals which are arranged in the manner
