time was spent under their sheltering roofs ; and both were 
indefatigable in obtaining specimens for us, interpreting with 
the natives, and getting us the vernacular names. The latter 
were never recorded without severely testing their accuracy 
by examining several individuals. 
Of the pleasant month we spent rambling amid the beautiful 
woods of Lifu, how we turned our good-natured friends’ 
houses into “shambles,” how we got shaken out of bed by 
earthquakes, &c. &c., are they not written in the pages of

XX.—Remarks on Dr. Gadow’s Papers on the Digestive 
System of Birds. By W. <A. Forsss, B.A., F.L.8., Pro- 
sector to the Zoological Society of London. 
Dr. Hans Ganow, who is already known as a worker at the 
anatomy of birds from his papers in the ‘ Journal fur Orni- 
thologie,’ has lately published in the ‘ Jenaische Zeitschrift ’ 
an elaborate article on the anatomy of the digestive organs of 
birds*. This paper, in two parts, extends over more than 
140 pages, and is illustrated with nine plates. 
In the first part Dr. Gadow gives a descriptive account 
(without histological details) of the alimentary canal and its 
appendages—tongue, liver, pancreas, ceca, &c., as well as of 
the kidneys, which he strangely includes with these organs— 
in the various orders of birds, in large part based upon his 
own investigations. I cannot always agree with Dr. Gadow 
in his grouping of the various forms together, as, e. g., inclu- 
ding such different forms as Auks, Penguins, and Grebes in 
the same order, “ Pygopodes.”’ 
For this part of his work Dr. Gadow seems to have ex- 
amined a large number of birds; but it is to be regretted that 
he has apparently had no opportunity of investigating some of 
the most interesting forms, such as the Tinamidee and Turni- 
cide. Had Dr. Gadow been acquainted with the structure
