 THE DEVELOPMENT OF CRANGON VULGARIS. 



SECOND PAPER. ^ 



(With Plates I and II.) 



BY J. S. KINGSLEY, SC. D. 



The observations here recorded were made at Salem, 

 Mass., during the summers of 1885 and 1886. I have 

 here to return my thanks to Dr. Henry Wheatland, Mr. 

 George D. Phippen and the Naumkeag Street Railway for 

 many facilities afForded me. The literatiire of crustacean 

 embryology has become so enormous that any resume of 

 the work of previous writers, even on the limited group 

 of decapods, is next to impossible. I have, however, en- 

 deavored to give proper credit in the text for all work 

 done by other embryologists, while appended is a bibliog- 

 raphy of the papers quoted. Füll titles are given of only 

 those papers which are not mentioned in Faxon's valuable 

 bibliography ('82). 



1 The flrst paper of the series is upon the development of the Compound eye 

 and appears in the fiist number of Whitman's "Journal of Morphology."
