VIII.J 



N.B. — The figures of Micrasterias are half the length of the 

 original drawings. The figures of Euastrum are engraved one- 

 third less than the drawings, except E. rostratum, E. spino- 

 sum and E. binale, which should be reduced in the same pro- 

 portion to compare them with the other species, all of which 

 are naturally larger than these three, and the original draw- 

 ings were in true proportion.

ERRATUM IN VOL. XIII. 



In the plate (PI. IV.) to illustrate Mr. Babington's paper on Cuscuta (p. 249) the numbers have 

 been misplaced by the engraver. Fig. 2. is C. approximata, and fig. 3. is C.Trifolii ; not as referred 

 to in the text.
