The plates are of the first order of excellence. Those illustrating 
the transformations and anatomy of the Corydalus cornutus are of un- 
rivalled delicacy, and the dissections by Mr. Leidy, who is distinguished 
for his skill in microscopic anatomy, are no where surpassed, 
plates of fossil footprints by Mr. Deane are ina good style of lithog- 
raphy, and accurately represent the character of the impressions. 
author figures some new species but without giving names. The article 
isan interesting sequel, if we tay so consider it, to Pres. Hitchcock’s 
elaborate paper in the preceding volume.
