fin occupies the whole length of the back. The anterior spine rises 

 between the anterior orbital margins : it is the longest and strongest 

 of all, its length being about f of that of the head. The succeeding 

 spines and rays gradually decrease to the seventh ray, which is about f 

 of the length of the head. The remaining rays abruptly decrease ; the 

 eleventh, being but \ of the length of the head, is attached to the tail by 

 a continuation of the dorsal membrane. All the finrays are undivided, 

 but jointed. The caudal is subrhomboidal or rounded, the longest, 

 central, rays are a little shorter than the head. The extent of the anal 

 fin slightly exceeds \ of the dorsal ; the two spines and the seventh 

 and eighth ray are a little shorter than the intervening rays, which are 

 \ of the length of the head. The lower half of the eighth anal ray is 

 attached to the tail by a very short continuation of the finmembrane. 

 The anus is situated a little in front of the fin. The pectorals are 

 elongated, rhomboidal, the central rays equalling the length of the 

 head. The anterior ventral ray, the longest, slightly exceeds \ of the 

 length of the head ; the fifth is attached to the abdomen by a conti- 

 nuation of the finmembrane. The lateral line is a series of linear 

 tubes, nearly following the outline of the back on the upper third of 

 the side. The fish appears to be without scales, but it is studded 

 with small tubercles, each surmounted by a minute, backward directed 

 spine. The tubercles may be seen by the naked eye, but their spines 

 may be perceived by passing a finger from the tail forward. On the 

 back, the sides of the head and body the tubercles are fewer, more 

 distant than on the throat and abdomen, where they are crowded. 

 The axilla and the space covered by the pectorals is naked. 



A solitary individual occurred at Pinang in July 1842.

Differs from Pelor by the want of teeth on the palate and vomer, 

 and of free rays beneath the pectoral fins.
