The author shows, and (unfortunately for the peace of mind 
of modern ornithologists) shows correctly, that the names be- 
stowed by P.,L. S. Muller must, according to the generally re- 
ceived principles of nomenclature, he adopted. They are those 
contained in the supplemental volume of his edition of Linnjeus’s 
^ Systema Naturae/ and having been published in 1776, and being 
strictly binomial, many of them (about 137) take precedence of 
those which have been commonly in use. Mr. Cassin prints a 
list of the names applied by Miiller, adding to them those which 
must now be considered synonyms.

By the terin Reptilian or Hemitypic Birds — for which 
the name Erpetoids Herpetoids) is also proposed — is 
meant the group to which the species known as Archoaopteryx 
macrura belongs. It is inferred that the young of this group 
were unquestionably unfledged, and quite probable that they 
were more completely unfledged, or for a longer period, than the 
young of ordinary birds. Further, that they were unquestion- 
ably walking chicks/^ .It is also probable that the Herpetoids 
had some more profound Reptilian characteristic than those 
already noticed, such as incomplete circulation ; and though the 
heart may have had its four cavities, there may have been a 
passage permitting the partial admixture of venous and arterial 
blood, such as exists not only in Crocodiles but in the young 
bird during an early stage in its development, and that this 
peculiarity may have continued on through the early part of the 
life of the chick, or until it was fledged.

respecting the direction taken by migrating Swallows, put by 
Dr. J. de la Harpe. The replies state that these birds in many
