synonymous C. s. fallax as 32.6 



my established perimeter, but 



than would be expected for an average. Some 



of the scutes along the central part of the straight 



lateral line have completed their development by 



16.1 mm. 



Lateral line. — Range of mean lateral-line ratio 

 above 60 mm. standard length: about 1.45 to 2.0 

 (fig. 78). Nichols (1939: 7) gave ratios of 1.35 

 and 1.4 for his specimens of 12 mm. and 15 mm., 

 which conform to my estimated perimeter. 



Preopercular spines. — Preopercular spines were 

 present on the specimen of about 13 mm. standard 

 length, and at 16.1 mm. and 17.1 mm. They were
