TOD. 42. 



There are over 50 specimens in the collection taken at depths of 83 

 to 395 fathoms. Although occasionally found with L. naresi, the 

 majority of the specimens were taken from greater depths than our 

 examples of the latter species, wliich came from depths of 83 to 214 

 fathoms. L. naresi is distinguished from olivaceus by the better 

 developed dorsal spines, of which there are six, by the position of the 

 third, its base being between the eyes instead of beliind them; by the 

 greater concavity of interorbital; by the better developed bony spines 

 of head, and filaments on head, body, and fins. The posterior arm 

 of the humeral spine is usually single and bent upward; in L. oliva- 

 ceus it is usually multifid.
