observations on the Modes and Factors of Evolution in the Mam- 
malia . J. Morph, v, pp. 301-406, pis. xxii & xxiii. 
Iu the first part of this memoir the author describes in detail the 
osteology of Mesohippus bairdi, which is considered to differ from Anchi- 
therium by the absence of infolding in the crowns of the incisors. It is 
regarded as one of the ancestral forms of the Horse, while it is suggested 
that Anchitherium is off the direct line. The second part treats in the 
same manner of Leptomeryx , which is regarded as a generalized Traguline, 
with certain resemblances to the Record , which appear to have been 
independently acquired. The third section discusses some problems in 
evolution, among which especial attention is directed to the importance 
of “ parallelism.”
