This species very closely approaches the preceding, uiul, 

 except for its minute size, is scarcely distinguishable from it. 

 Such was the opinion entertained on reading Pourtales's de- 

 scrij)tion ; and a recent ojiportunity afforded me by Dr. Duncan, 

 of consulting liis type specimens, only confirmed me in the 

 conclusion 1 had then arrived at.
