Figure 30.— Relation of snout length, of maxillary length, of distance from tip of snout to origins of dorsal and anal 

 fins, and of distance from tip of snout to dorsal-fin termination to standard length in Pseudopriacanthus altxis. (Dashed 

 lines serve as guides in the separation of series of dots.) 



In a 67.3-nim. individual (fig. 19), pigment of 

 the dorsal fin consisted of onlj- the black tips of 

 the anteriormost soft-rays and traces of the lines 

 parallel to the spines. In larger individuals, 

 through the largest (261.8 mm.; see fig. 23), the 

 lines of pigment parallel to the spines persisted in 

 ever lessening degrees of intensity. The dark edge 

 of the soft fin persisted without loss of intensity, 

 and was broadest on the most anterior rays; if 

 was never observed on the tips of tlic one or (wo 

 most posterior soft-rays. 



Anal Jin. — The pigment pattern and its devel- 

 opment on the anal fin were so similar to those of 



the dorsal fin, both in sequence and in size of fish 

 at which the pattern developed, that it is unnec- 

 essary repetition to describe them here, other 

 than to note a few minor differences. 



Pigment on the anal fin was first observed on 

 an 8.2-mm. specimen. Two rows of light spots, 

 plus the light tips, appeared to be the maximum 

 development of this pattern on the spinous fin, as 

 seen at 34.0 mm. (similar to the maximum spot- 

 ting on the spinous dorsal fin; see fig. 15). Lines 

 of pigment parallel to the spines developed sub- 

 sequent to the spots. The fine anterior to the 

 second spine persisted to about 65 mm., whereas
