nasal opening is wide, crescent-shaped, with the convexity turned 

 forwards, situated on the upper side of the head. Spine at the angle 

 of the praeoperculum very indistinct ; limbs of the pi?eoperculum 

 subequal in length. Caudal fin rounded. Spines of the fins very 

 strong, deeply striated, without roughnesses ; the second and last 

 dorsal spines subequal in length, but much shorter than the fourth 

 and fifth, which are the longest. The ventral fins reach to the anal 

 fin. Uniform reddish rose-coloured. Vertical and ventral fins with 

 a black margin. 



One example, 10| inches long, has been sent from Manado by 

 Dr. B. Meyer.

The height of the body is contained twice and two thirds in the 

 total length (without caudal), the length of the head twice and one 

 fifth. The diameter of the eye is one fifth of the length of the head, 

 or two thirds of that of the snout. Upper jaw scarcely longer than 

 lower ; maxillary not extending to the front margin of the orbit. 

 The posterior limb of the prseoperculum emarginate, with the angle 

 rounded, denticulated, but not produced. Spines of the fins very 

 strong ; the two anterior of the dorsal very short, the second not half 

 as long , as the third, which is the longest, and nearly half as long as 

 the head. The other spines become gradually shorter, the last being- 

 only half as long as the first ray. The second anal spine is much 

 stronger and longer than the third, and nearly as long as the third 

 dorsal spine. Caudal fin truncated. Pectoral pointed, extending to 

 the vent. Silvery ; upper half of the body with small blackish spots, 

 which occupy the base of the scales. Dorsal fin with two rather 

 irregular series of round blackish spots, each of the size of the pupil. 

 The other fins immaculate, or with a slight blackish tinge. 



One specimen, 13 inches long, has been obtained at Mauado by 

 Dr. B. Meyer.

The height of the body is contained twice and three fourths in the 

 total length (without caudal), the length of the head thrice and a 

 half. The diameter of the eye equals the extent of the snout, and 

 is contained thrice and two thirds in the length of the head. The 

 maxillary extends to the front margin of the eye. The third to 

 seventh dorsal spines are equal in length, one third of the length 

 of the head, and not much longer than the following. All are of 

 moderate strength. The length of the longest dorsal rays is less 

 than one half of the depth of the body. Caudal fin emarginate, 

 with the lobes rounded. The second and third anal spines sub- 

 equal in length, and much stronger than those of the dorsal. The 

 pectoral is rather shorter than the ventral, which does not quite
