D. xii/19 ; A. ii/20; P. 14 ; V. 2 ; C. 13. Depth equal to the 

 leiigtli of the head, and nearly 5 in the lenj^th to the hypuial joint. Eye 

 3.1 in the head. Last dorsal spine l!, sixth dorsal ray 1.1, and the fifth 

 last anal ray 1.5 in the head. 



Head about as hig'h as long', with the forehead subvertical. Eyes 

 close to the upper anterior profile, se[)arated by a narrow concave inter- 

 orbital space. A crest is present on the occiput. Nasal, ocular and 

 nuchal tentacles present, all short and simple. A single I'ow of fine teeth 

 in each jaw, and a stout, curved, internal canine is j)resent on each side 

 of the mandible. 



Dorsal fiu not notched, but the spinous portion lower than the soft. 

 The s{)ines increase slightly in length backwards, and the base of the 

 spinous porticui of the fin is shorter than that of the soft dorsal. The 

 rays are subequal in height, and the last is joined to the base of the caudal 

 by membrane. Anterior anal I'ays a little produced, filamentous ; the 

 others subequal, and the last united to the caudal peduncle by membrane. 

 Pectoral obtusely pointed, fifth lowest ray longest, but not reaching the 

 vertical of the vent. Inner ventral ray longest, reaching almost half its 

 distance from the vent. Caudal a little rounded, most of its rays 

 bifurcate. 



Coluur iiiarkiny. — Light greyish bi'ovvn after long preservation in 

 alcohol, with eight broad br<)wn cross-bands which are much broken up 

 by ligliter spots anteriorly. Base of pectoral and breast with broad 

 brown markings enclosing lighter spots. Head mottled with rounded 

 lighter spots and brown markings, which extend across the throat. 

 Small blue ocelli are present on the up[)er portion of the dark cross-bands 

 posteriorl3^ Dorsal fin with dark blotches, wliich are continuations of 

 the cross-bands of the body ; these curve forwai'd and tend to form two 

 horizontal bands on the outer half of the spinous dorsal. Anal dusky, 

 darker iowards its niaigin ; Ihe other fins plain, the caudal with two 

 dark basal blotches. 



Described and figured from a cotype preserved in the Macleay 

 Museum, 76 mm. long. Twelve others, 34-84 mm. long, do not exhibit 

 any marked variation, though the cross-bands are more distinct in some 

 than in others. 



Siiiininjviy. — Kluiizinger suggested the identity of his N. pmictillatus 

 with »S'. f^piddiiuji, but Macleay believed the two to be distinct. Klunzin- 

 ger's desciiption agrees with Macleay's specimens quite well in all 

 structural details, and the slight differences in the colour marking is 

 evidently due to variation. 



Loc. — Port Darwin, Northern Territory.
