its scaly sheath. The value of the first character is questionable, 

 as the species of Parapristipoina show a regular gradation in num- 

 ber of anal rays up to the number in the present species, and the 

 character of the scaly sheath is apt to be misunderstood, as there is 

 present in I. conceptionis (at least in the specimens at hand) a 

 slight development of scales at the base of the anal, two or three 

 scale-rows deep and at its widest part about one-ninth the length 

 of the longest ray. On the other hand, the sheath in Parapris- 

 tipoina trilineatum, the type of that genus, is, according to Bleeker's 

 figure,^' about two-fifths of the length of the first ray, and com- 

 posed of 7 or 8 scale rows at the Avidest part. The preopercular 

 spines of /. coiiceptmiis are weak and partly hidden by the skin 

 and there appears to be no special development of them at the 

 angle. The spines of Parapristipoina are rather strong, especially 

 at the angle.
