List of Species.

The last three cannot be positively identified without a reexami- 

 nation of the specimens, which are not, at present, accessible to me, 

 for they were sent to Europe, for study, many years ago. 



In addition to these, Mr. Agassiz described and figured, in the same 

 paper, some unknown annelid larva? ; one which he supposed to be the 

 larva of a Nemertean (? Nareda Girard), and considered the same as 

 " Loven's annelid larva," which, in the light of subsequent observa- 

 tions, is an annelid, probably identical with, or allied to Polygordius; 

 and also the larval forms of Planaria angidata. The latter is not 

 the Planaria angulata of Fabricius, which was a Nemertean, but is 

 a true Planarian (the Bdelloura Candida Leidy).
