nostrils, over and beliiml tlie eye, to the groove above the opercles ; others 

 cross the cheek and operculum, and extend around the preopercular 

 margin and onto the mandible ; no large open pores. Kyes separated by 

 a bi'oad, flat, interoi-bital s[)ac'e ; some small impei'l'ect scales on tlie n[)per 

 paj't of the eye. Snout broadly i-ounded, the mandible projecting, 

 ifouth oblique, the maxilla reaching to below the anterior thiid of the 

 eye. Anterior nostril in a sliort tube near the li[), the jxisfeiior a simple 

 opening on the upper surface of the head. A broad band of villiform 

 teeth in each jaw, palate toothless. Tongue rounded anteriorly, and 

 largely free. Gill-openings lateral, and continued somewhat forward 

 below, the isthmus separating them wider than the eye. Exposed edge 

 of the shoulder-girdle smooth. 



Body robust, compressed posteriorly, covered with ctenoid scales, 

 which extend over the breast and bases of tlie pectorals. They are a 

 little larger posteriorly than anteriorly. Genital papilla well developed. 



First dorsal fin rather low, rounded, and commencing well behind 

 the pectoral base ; the penultimate spine is longest, and reaches beyond 

 the first I'ay when adpressed. Second dorsal oblong, pointed posteriorly, 

 the margin sti^aight ; the penultimate ray is longest, and reaches the 

 vei'tical of the hypuiul joint. Anal opposite the second doi'sal, and 

 similar in foi'ra thougli a little more I'ounded anteriorly. Pectoral 

 rounded, tlie median rays longest, and almost reaching the vertical of 

 the last dorsal spine. Ventral inserted below the pectoral-base, the fourth 

 ray longest, and reaching about two-thirds of its distance fi'om the vent. 

 Caudal broadly rounded. 



Colour-marl-iiiij. — Light brown in alcohol, wnth numerous darker 

 spots along the middle of the sides, which coalesce posteriorly into two 

 longitudinal lines enclosing large darker and lighter blotches. Two 

 oblique stripes cross the cheek from the eye, and are continued across the 

 opei^culum ; a third crosses the opetculam and the base of the pectoral to 

 a dai'k blotch on the bases of the I'ays. First doi'sal dusky, with some 

 obscure darker spots, and a white bolder. Second doi'sal dusky, with a 

 white border and numerous large darker spots near the base and on the 

 posteiior rays, where they mingle with some lighter markings. Anal 

 with markings similar to tliose of the second dorsal. Caudal with dark 

 spots between the rays on its median portion, which are largest near the 

 base. 



Described from an adult specimen 120 mm. long, from Port Essington, 

 which is somewhat faded, but exhibits all the charactei'S of the species. 



JdeiUlti/. — This specimen, and the others referred to below, differ 

 from Richardson's description of E. iiioijiirniJd, also from Port Essington, 

 in having fewer I'ays in the dorsal and anal fins, but it must be noted 

 that Giinther later re-examined the types and found them constructed as 

 in our specimens. Giinther counted forty-eight scales in a longitudinal 

 series, which is a larger number than we find in any of oui^. 



Vitriatiou. — Three specimens, also from Port Essington, 25-42 mm. 

 long without the caudal fin, exhibit some variation in the number of 

 fin-rays and scales ; D. viii-ix/12-13 ; A. 12 ; oS-tO scales between the
