Note. The brief description given by BLEEKER of his 

 Polynemus diagrammicus gives no clue as to the exact position 

 of this species. It is possibly identical with P. pfeifferi, the 

 differences given by BLEEKER in his description of lastnamed 

 species being easily explained by differences of age. The last 

 mention made by BLEEKER of P. diagrammicus is in his 

 "Enumeratio piscium" etc. (Act. Soc. Sc. Indo-Neerl. VI. 1859, 

 p. 39). This makes us suppose, that the specimens were lost. 

 They are neither in the British, nor in the Leiden Museum. 



In these circumstance we think it safest to place P. dia- 

 grammicus as a doubtful synonym of P. pfeifferi.

Height 3.4 3.5, 4.7 4.8 in length with caudal. Head 3 3.5, 

 4.3 4.7 in head with caudal. Eyes 3.2 3.7, about twice in 

 postorbital part of head, and somewhat less than convex inter- 

 orbital space. Snout shorter than eye, prominent. Mouth large, 

 reaching far behind eye. Maxillaries scaleless (in three speci- 

 mens examined), 2.1 2.3 in head. Head covered with scales 

 to end of snout. Anterior and posterior nostrils close together, 

 about midway between eye and end of snout. Praeoperculum 

 rather strongly serrated, the inferior spines somewhat stronger, 

 its angle produced into a triangular flap. Upper lip absent, 

 lower lip well developed but not continuous at symphysis. 

 Narrow bands of teeth in jaws, palatines and head of vomer, 

 those of the jaws not extending to the outside. Origin of dorsal 

 between that of pectorals and ventrals. First dorsal spine of 

 first dorsal minute, second one shorter than the third, but 

 somewhat stronger, slightly shorter or longer than postorbital 

 part of head. Origin of second dorsal in advance of that of 

 anal. Spine of second dorsal about 2 / 3 of second spine of first 

 dorsal, longer than second spine of anal. First anal spine minute. 

 Dorsals, anal and caudal scaly. Caudal very deeply forked,
