1 The designation of Ela-sraodus having 

 been preoccupied by Sir Philip Egerton 

 for a series of fossil fish, Dr. F., in 1857 

 substituted the term Euelephas for 



-This is erroneously designated E. 



".s in the plate (see note, page 23). 



The illustration is taken from Nesti's 



figure. The skull is nearly perfect in 



the frontal and occipital regions, con- 



perfect in the facial portion, the border 

 of the nasal opening being broken, to- 

 gether with the terminal portion of the 

 incisive alveoli and zygomatic arches. 

 The line formed by the posterior border 

 of the vertex is transverse, the fossa 

 being overarched by a produced fold of 

 the vertex.
