axil of pectoral, possibly damaged, about f length of fin. ^^entral with 

 a similar scaly flap which is about half length of fin, and a broad one 

 between base of each which is a little over half of ventral, possibly 

 damaged. Greater portions of rayed dorsal, anal and caudal densely 

 scaled, those basally lai'ger. 



Spinous dorsal inserted a little nearer tip of snout than base of caudal, 

 first spine longest and fourth shortest. Soft dorsal inserted nearer 

 base of caudal than origin of spinous fin, and first ray longest. Anal 

 similar to soft dorsal, spines slender, graduated to third which is long- 

 est, second but little shorter, and first hardly -j length of second. Ori- 

 gin of rayed anal well in advance of that of rayed dorsal. Caudal emar- 

 ginate, lobes distinct and pointed. Pectoral small, not quite reaching 

 opposite origin of spinous dorsal, and its origin a little above middle of 

 vertical orbital diameter. Ventral inserted about opposite middle of 

 pectoral and its spine about § in length of fin. 



Color in alcohol pale brownish with more or less silvery reflections. 

 Back and upper surface darker brownish. Fins all pale l^rownish. 

 Iris brassy. 



Length 4^ inches (caudal damaged). 



One example. 



Mugil helanak Bleeker^^ is the first name available for the present 

 species. Bontah RusselP^ is not available, but it forms the basis of 

 Mugil bontah Bleeker^^ which is its first introduction in a binomial 

 sense. Later Bleeker identified other specimens^* under the same 

 name which appear to be different, and which have been referred to 

 M. helanak by Dr. Giinther. However, Russell's figure of Bontah had 

 been named by Swainson as Mugil gymnocephahis}^ This, according 

 to Day, would lead to its identification with Mugil our Forskal. The 

 discrepancies between my account and that by Day^* are probably due 

 to age.
