Of the general scope of this work we have already spoken 
(suprhy pp. 67, 68). Four of the plates are devoted to illustra- 
tions of the eggs ; hut the figures only give a general idea of 
what the originals are like, and are entirely wanting in specific 
character, though most are figured for the first time. The fol- 
lowing is a list of them - 
Plate I. Hypotriorchis columharius, Tinnunculu^ sparverius, Accipiter fusousj 
Bitteo lineatus, B. pennsylvanicus ; Plate II. Myiarchus crinituSy Parula ame^

No species appears to have been noticed that was not previously 
known as frequenting the district.

In apparent unconsciousness of M. O. des Murs^s ^Oologie 
Ornithologique,^ the author states that his is the first attempt 
to bring oology into system, or to treat that study scientifi- 
cally. The result, according to his determination of oological 
characters, is that Upupa stands between Mergulus and Alctty 
and Regulus between Anthus and Ibis. It must not, however, 
he thought from this that the author is in favour of such an 
arrangement ; on the contrary, a systematic list, based on Prof. 
SundevalFs classification, concludes the volume. In describing 
the eggs of birds, Herr Wester! und adopts four categories: — 
(1) Ovate {ovata)y (2) Oval {ovala)y (3) Pear-shaped {pdronfor- 
miga)y and (4) Spindle-shaped [spolformigt) . {Cf. Ibis, 1868, 
pp. 113, 114.)

This paper contains the result of many Observations on the 
variation in the colour of birds^ eggs ; but, so far as we can 
gather from it, the author does not arrive at any very definite 
conclusions on this neglected subject.
