 connection Avhatever with the transverse processes of any vertebrre 

 anterior to the ilium, so far as I have been able to ascertain. In 

 re-examining Jfegaloj^hrys nasuta for purposes of comparison with 

 the pi-esent species, I find that my description is correct, but not 

 sufficiently detailed for purposes of accurate comparison with the

 transversalis muscle of the oesophagus arises from the pubis, as I 

 have already stated. The exact mode of connection is shown in 

 the figure annexed hereto (text-fig. 229), and will be seen to be 

 not very difierent from that of Megcdophrys montana.
