McCULLOCH AND WAITE — TwO NEW AUSTRALIAN GOBIES 81 



unites with the hasc of the anterior dorsal s])ine: eves of moderate size, separated 

 by a narrow interorl)flal s])ace, and eacii with a stout tentacle: snout forming a 

 comex cur\e with the upper i)rr)tile of the head: anterior nnstril in a short tube 

 near the lip. the jioslericr one is a lart,'e simple dpenintj in the middle of the 

 snout : maxillary pointed posteriorly, reachinij Ijackward to below the hinder third 

 of the eye: mandible slightly longer than the upper jaw : premaxillary teeth cardi- 

 form, suliequal. in a single >eries: mandibular teetli in a narrow band, the inner 

 pnes somewhat enlarged, the others xilliftirm : no distinct canines: palate toothless: 

 tongue obtusely i)ointed, only its ti|) free: gill-openings lateral, separated by a 

 broad inters])ace. which is aljout one and, one-half times as wide as the eye: 

 shonlded-girdle smooth, without pa])illae. 



Txidy moderately deep, covered with scales which are ctenoid as far forward 

 as the second dors.al and cycloid anteriorly: they extend forward to the sides of 

 the nape ,abo\-e the preopercular ni;irgin, ;ind on lo the breast, but the pectoral 

 base is naked: genital pa]iill;i well de\eloped. 



fins. First dorsal connnencing behind the pectoral base, its sjiines fila- 

 mentous, the second reaching backward to aliout the middle of the soft dorsal ; 

 the membi-ane from the last almost connects with the base of the first ray: second 

 dorsal nuich <l:iinaged, the rays increasing in length backward : the posterior ones 

 o\erlap the base of the caudal : anal commencing beneath the second or third 

 dorsal raw and terminating slightly behind the last; the rays increase in length 

 backwards, and the posterior ones overlap the caudal base : pectoral obtusely 

 pointed, median rays longest, reaching to the \ertical of the third anal ray: ventral 

 large, whollv united, almost reaching the \ent : caudal pointed, the median rays 

 l>rodueed. 



Coloiiy-iiuvkiiuis. N'ellowish in alcohol, with dusky blotches along the sides 

 and back; each scale of the back with a d;irk round spot near its margin: head 

 and nape with some s\mmetrical markings, the most distinct of which is a dark 

 patch under the eye and another on the operculum: first dorsal fin with horizontal 

 rows of dark-edged ocelli between the spines: second dorsal with numerous 

 double rows of inter-ra<lial blackish spots: elongated dark spots between the rays 

 of the upper half of the caudal : numerous small, dark, inter-radial sjiots on the 

 pectoral : membrane of the ;uial fin dusky. 



Described and figured from a single specimen i_^5 mm, long, which is, unfor- 

 tunately, somewhat damaged. It is very similar in both form and colour-marking 

 to an Indian example of O. cristatus Day. with which we have compared it. but 

 its scales are largely ctenoid instead of wholly cycloid. It is also ai)])arently very 

 close to other species-of (Kryiirichtliys. such as O. li'iitaciilaris Cuv. and Val., and 

 (). iiiicrnlcpis P>leeker. Ijut the combination of a nuchal crest, ocular tentacles, 

 scale-counts and colour-markings appear to distinguish it from all.
