86 NEW GENERA AND SPECIES OF AUSTRALIAN FISHES, 



in that of the snout,* while in Morton's example the correspond- 

 ing figures are only a trifle more than four in the head — dermal 

 flap included — and one and a third in the snout. 



If, therefore, Johnston's measurements be correctly given, I 

 am compelled to consider his species as different from mine. 



Dermatopsis macrodon. 



Since publishing the description of this species (Proc. Linn. 

 Soc. J^.S. Wales, xxi. 1896, p. 140) a second example, not quite 

 so large as but in much better condition than the type, has been 

 discovered among a number of small, principally immature, fishes ' 

 collected at various times by Mr. Whitelegge on Maroubra Beach 

 and handed by him to me for identification and, if necessary, 

 description. 



An examination of this specimen has enabled me to supplement 

 or correct the original diagnosis in the following particulars : — 



The depth of the body is 5i in the total length, the abdominal 

 region not being shrunk as in the type; the eye is only perceptible 

 as a dull bluish patch, which is scarcely larger than that covering 

 the posterior nostril, to which it has a similar appearance; its 

 diameter is apparently about one-twelfth of the length of the 

 head; the profile of the snout is distinctly rounded; the jaws are 

 of equal length and the lower labial flap is absent; there are two 

 distinct dorsal tubercles, the anterior situated immediately in 

 advance of the vertical from the base of the pectoral; its distance 

 from the posterior is about two-thirds of that between the latter 

 and the origin of the dorsal fin, this distance being as long as the 

 space between the posterior nostril and the extremity of the 

 snout ; the dorsal fin originates somewhat further back, its 

 distance from the extremity of the snout being 3f in the total 

 length, while the origin of the anal is distinctly in advance of the 

 middle third of the dorsal and a little nearer to the base of the 

 caudal than to the extremity of the snout ; the length of the 



These measurements agree with those of the small-eyed richardsonii.
