keep them as long as you need them. You can use them as copy and thus avoid the 
task of transcribing.” 
The synonymy of the Embiotocidce in the following review to 186S is Dr. Gill’s, 
with only slight alterations. The etymology of the generic names is also reproduced 
here as given in his unpublished work. Such other portions as I have incorporated in 
the paper, I have indicated by quotation marks, also giving direct credit for the same. 
I wish to express my thanks to Dr. Silas M. Mouser, of San Francisco, in whose 
laboratory the sections necessary for the part of the work here presented were made. I 
wish also to acknowledge my indebtedness to ex-Governor (now United States Senator) 
G. C. Perkins, of San Francisco, for enabling me to visit various parts of the coast of 
California. I am under similar obligations to Mr. A. R. Towne, of the Southern Pacific 
Railroad Company. Dr. Howard Ayres kindly furnished me with references to the 
bibliography bearing on some of the points. Finally, Mrs. Eigenmanu assisted me in 
all the stages of securing and preserving the material, rendered much assistance in 
preparing the paper, and corrected all the proofs. 
A REVIEW OF THE EMBIOTOCIDCE 
[By Carl H. Eigenmann and Albert B. Ulrey.] 
The writers have attempted in this paper to collate the various references to the 
species of Embiotocidce and to present a synopsis of the genera, together with brief 
descriptions of the species. 
Most of the American species have been examined by us, and in order to deter 
mine the number of valid genera skeletons have been prepared. These show that the 
earlier authors have been more fortunate in their opinions concerning genera of 
Embiotocidce than the more recent ones. The genus Ditrema has been admitted on 
second-hand knowledge. As yet no one has given any very lucid characterization of 
this genus as distinct from Embiotoca and external differences seem to be wanting.
