Orr and Blackburn: Resurrection of Sebastes variabilis and redescription of Sebastes ciliatus

thickness, caudal-peduncle dorsal length, and upper-jaw 

 length (Table 6). No significant regional variation was 

 observed within the overall PCA. 



In the sheared PCA of differences in shape by depth, 

 both species showed negligible differences within broadly 

 overlapping clusters of individuals. In the depth analysis, 

 loadings along the PC2 axis were strongest for suborbital 

 depth, gill-raker length, and orbit length, and shallower 



individuals tended to have a greater suborbital depth, 

 longer gill rakers, and longer orbit. In the combined mor- 

 phometric and meristic shallow-water analysis, slight 

 differences along the morphometric PC2 axis and the 

 meristic PCI axis reflected longer gill rakers and higher 

 lateral-line pore counts in S. variabilis. No differences 

 were found in the PCA comparing sex within species 

 (Tables 7-8).
