llah. Atlantic coasts of America from the United States 

 to Brazil, in deep water (40 to 200 fathoms). 



An example of 250 mm. in the British Museum, from the 

 North Atlantic, sliows tlie typical coloration of the species. 

 The back is crossed by seven pairs of narrow blackish trans- 

 verse stripes, the fourth and tilth of which pass through the 

 bases of the lirst and second dorsal fins respectively ; on the 

 sides these strijjes give rise to a network with large polygonal 

 meshes. Goode and Bean give the name S. boa to a variety 

 which appears to be identical with the recently described 

 C'. hax'kelii ; the paired stripes are replaced by dark bars 

 studded with darker spots, and the reticulations on tiie sides 

 are broken up into spots and vermiculations.
