Eleotris pseudacanthopomus, Bleek. Sumatra, ii. p. 276, is probably 

 identical with this species. Bleeker compares it with the following 

 species {E. melanosoma), and adds that it may be distinguished by the 

 operculum, which is entii'ely scaly, and by a small canine tooth in 

 the lower jaw. Eleotris hracliyurus (Bleek. Verhand. Batav. Genootsch. 

 xxii., Blenn. en Gob. p. 20) has been referred to E. pseudacanthopomus 

 by Bleeker himself. See Enumer. Spec. p. 114. 



Air-bladder large. 



Skeleton. — The crown of the head is entirely smooth, only a trace 

 of an occipital crest being visible ; it is broad and somewhat convex 

 along the middle ; the interorbital space is of moderate width. The 

 intermaxillary is considerably shorter than the maxillary, and dilated 

 at its extremity ; its posterior processes are of moderate length. 

 The articulary and the posterior part of the dentaiy bone of the 

 mandible have a broad horizontal lamella interiorly. The margins 

 of the praeoperculum are simple ; there is a spine at the angle. The 

 pubic bones leave a free space between them, and are elongate, tri- 

 angular ; they do not extend to the humerus, to which they are joined 

 by a broad, flat cartilaginous lamella. Eleven abdominal and fom'teen 

 caudal vertebrae.

Prseoperciilum with a spine directed downwards. The scales on 

 the upper sm-face of the head are small, extending over the fore- 

 head ; cheeks naked. The height of the body is one-sixth or one- 

 seventh of the total length, the length of the head one-fourth. The 

 diameter of the eye is contained four times and a half or five times 

 and a half in the length of the head, and three-fifths of the width of 

 the interorbital space. The upper jaw is shorter than the lower, 

 and extends backwards to below the middle of the eye. Teeth 

 viUiform, fonning bands. Blackish-green ; fins variegated with 

 black. {Bl.)
