Some Additional Remarks in relatio?i to the Fibres, which 

 compose the Eggshell of Oviparous Snakes — by Dr. 

 D. F. Weinland. See page 28. 



Since the time I wrote on the egg-tooth of snakes, and on 

 the composition of their eggshell from fibres, similar fibres have 

 been observed by Ernst Haeckel, of Berlin, in the eggshells of 

 some fishes, viz : of the whole family of Scomberesocidse (Exo- 

 cetus, Tylozurus, Hemiramphus, Scomberesox and Belone.) 

 Also, they have been seen by Mr. Haeckel to originate from 

 cell-like roots, just as we found it in the fibres of the eggshells 

 of snakes. Yet the two are by no means homologous, as it 

 might first seem ; for the fibres described by Haeckel are situ- 

 ated inside of the yolk membrane, so as to surround the yolk 

 immediately, while the fibres which I have described compose 

 the chorioa that ia the outercoating of the egg. D. F. W.
