 A near relation and perhaps local representative of G. seml- 

 cinctics Ben. a Mauritian species. 



GOBIUS CONCOLOR. 



D. G, 1/11. A. 1/10. Lat. 26. Tr. 8. 



The height of the body and length of the head are equal and ^ of 

 the body s c. Orbit and snout equal and \ of the length of the 

 head, interorbit 1 of the orbit, and preorbital 2f in the length of 

 the head. Head over the operculum as high as long, its breadth 

 I of its length. Upper profile from the end of the second dorsal to 

 the snout regularly convex. A small canine on each mandible, 

 lower jaw the longer. Ventral reaching the anal with its basal 

 membrane but slightly developed. Upper rays of pectoral detached, 

 silky. Nuchal scales nearly as large as those of the body. Uniform 

 brown, abdomen paler with some irregular traces of narrow vertical 

 bands. First dorsal with two longitudinal rows of brown spots. 

 Pectoral and ventral dark brown. 



Locality, Cape York. Collected by Mr. K. Broadbent. 



GOBIUS PLAVESCENS. 



D. 6, 1/J0 A. 1/9. Lat. 30. Tr. 7. 



The height of the body is 6f , the length of the head 3§ in the 

 total length. The orbit equals the interorbit, and the snout is \ of 

 the length of the head. Head longer than high and longer than 

 broad. Snout rounded, obtuse. Physiognomy of Mugil dobula. 

 Teeth moderate. No canines. No loose rays to the pectoral. 

 Jaws sub-equal, the lower rather the shorter. Scales of the nape 

 and occiput large. Caudal short pointed, occasionally enveloped 

 for the most part in mucous tissue, ventral short, rounded. Pale 

 grey with a yellow tinge, irregularly freckled with black and with 

 more or less obsolete traces of a lateral series of spots of which the 

 last on the base of the caudal is more constant. Ventral with a 

 dark intramarginal line. 



Locality, Moreton Bay. Collected by Mr. G. Watkins. Nearly 

 allied to G. ornatus, Rupp, but with smaller scales, the upper 

 pectoral rays attached and the eyes further apart.
