SOME ArSTIULlAN ni.KNNiniD FISHKR McCDLLOCH AND McNEII-I,. 19 



D. xiii/21 ; A. i/22 ; r. 14 ; V. 2 ; C. 13. Depth 5 in the length to 

 the hypuial joint ; head 5 in the same. Eje 8.5 in tlie head; interorbital 

 space -i in the eye. Median dorsal sf)ines 2, median dunsal lays 1.5, 

 posterior anal rays 2 in the head. 



Head longei- than liigh, with a snbvertical ft)rehead ; no occipital 

 crest. A huge arborescent ocular tentacle, and a small one at each anterior 

 nostril ; no nuchal tentacle. Mouth reaching well beyond the vertical of 

 the hinder orbital margin. Teetli very small, in a single low in each jaw ; 

 no canines present in either. 



Dorsal tin deeply notched, commencing above the p(jsterior part of 

 tlie operculum, the spinous portion a little shorter than the soft ; the 

 median spines are the longest, and the margin of the fin is slightly 

 rounded. Dorsal rays siibequal, highest in the middle of the fin, and 

 longer than the spines ; the last is joined by membrane to the extreme 

 base of the caudal. Anal rays increasing in length slightly backwards, 

 the last not united to the peduncle by membrane. Pecto)al obtusely 

 pointed, the fifth lowest ray the longest and not quite reaching the verti- 

 cal of the vent. Inner ventral ray longest, reaching less than half its dis- 

 tance from the vent. Caudal rounded, the inner rays bifurcate. 



i'ulonr iiiarkiinj. — General colour, dark brown in alcohol, lighter 

 posteriorly, with some obscure darker cross-bands on the hinder portion 

 of the back, and dark brown spots on the tail region. The head is ob- 

 scurely mottled on the operculum and throat, and thi'ee dark bars descend 

 from the eyes across the lips. Dorsal fins with rows of angular dark 

 brown spots, connected by lines, and together forming a more or less zig- 

 zag pattern which runs parallel to their mai'gins ; soft dorsal with oblique 

 lines on its basal half. Caudal with irregular transverse rows of dark 

 spots on the rays. Pectoral and posterior portion of anal obscurely 

 spotted, the latter fin with an indefinite darker submarginal band. 



The above description is based upon the holotype of S. auri(h-ii!', 84 

 mm. long, and supplemented with notes on the colour marking of additional 

 specimens from Murray Island which agree in all details with Alleyneand 

 Macleay's example. One of the latter, 94 mm. long, is figured. 



Another specimen from Two Isles, off Cape Bedford, is much lighter 

 in colour and shows the transverse body-bars and head markings much 

 more definitely than the others. 



Synoiiyiii I/. — We have compared these specimens with an example 

 from the Andaman Islands, which was identified by Dr. Day as N. )his.</(- 

 7nieri\ and find no differences between them. 



S. cheverti, Macleay, is represented in the Macleay Museum collection 

 by sevei'al cotypes, all of which differ from the very imperfect description 

 of that species in having more numerous spines and rays in the dorsal and 

 anal tins, and in their colouration. But tliey are clearly labelled, and are 

 evidently the specimens upon Avhich the species is based. They are 

 covered with a light bluish sediment, but wlien this is removed they are 

 found to have the same colour marking as the holotype of ;S'. unrideiis, 

 to which they ai-e similar in all details.
