By F. R. COLE. 



EXPLANATION OF PLATES. 



The numbers correspond in all cases except No. 217 to the number assigned to the 

 species in the text. There are six species for which we have no drawing, Noa. 13. 

 76, 81, 118, 139, 143. What should have been number 130 has been placed at the end 

 of the drawings as No. 217, it being made after most of the plates were made up.
