the shell membrane is tough, and the white very sticky. Before 
studying his eggs he took them to Williamstown, Mass., but 
before arriving there they had undergone a part of their develop- 
ment, and the neural folds had nearly completed their coalescence. 
ANATOMY oF Brrps.—Mr. F. E. Beddard (P. Z. 8S., London, 
1888) gives an account of the alimentary tract and syrinx of 
Balæniceps rex, from which, and from the previously known 
osteological peculiarities, he regards this bird, “in fact, as a rather 
aberrant heron, having no near affinities with the storks, nor to 
Scopus.” In the same volume he has some notes on the visceral 
anatomy of the penguins and puffns, dealing especially with the 
oblique septum of these birds, and the morphological and taxonomic 
conclusions to be drawn therefrom. He is inclined to homologize 
it in details with a fibrous and even muscular stracture found in 
the crocodile. Dr. R. W. Schufeldt (Jour. Comp. Anat. and Sur- 
gery, October, 1888) gives a much needed account of the osteology 
of the Jungle-fowl, Gallus bankiva. He also treats of several other 
important structures in the same bird, which is of especial interest 
as being the ancestor of all of our domestic fowl. Some thirty 
process figures illustrate the chief points in the article. 
ENTOMOLOGY." 
CoLOR-RELATIONS BETWEEN PUPÆ AND THEIR SURROUND- 
INGS.—Students of Lepidoptera often observe variations in the 
color of different pups of the same species, that have apparently 
been caused by the color of the object to which the pupa is attached. 
Striking instances of these variations came under the observation of 
the writer during the past summer, when breeding Papilio asterias. 
Pupz attached to green leaves were bright green in color, while 
others attached to the sides of a breeding-cage closely resembled in 
color the wood upon which they were. 
This class of phenomena has been made the subject of careful 
study by several English entomologists. The more important ot 
the papers published are two in number. The first, by Mr. E. B. 
Poulton,? was read before the Royal Society of London last year. 
Since that time Mr. George C. Griffiths has carried the matter 
farther, and the results of his experiments have just been published 
by Mr. William White.’
