associated mode of growth. How, if that is the case, arc 

 we to explain the detached mode of growth of many of the 

 species ? how their growing from the outer surface of the 

 solid valves ? and how they are communicated to new sites? 

 analogy is too strong altogether to permit us to doubt that 

 they do not resemble the Balani in this particular. No 

 doubt the appearances exhibited pL CL. coupled with the 

 fact of the ova being found within the pedicle, are calculated 

 to mislead, but we perceive the associated species of Lepas 

 attaching themselves indiscriminately to the valves, the 

 pedicle or its basis, as well as to all sorts of ifloating bodies.
