executed plates. The Report will be published as soon as the 

 plates can be reproduced. It will form an important contribution 

 to our knowledge of the Paguridae. Messrs. Goode and Bean hope 

 to finish their Memoir on the " Blake " Fishes within a few weeks. 

 Fair progress has been made on the Memoirs and Bulletins men- 

 tioned in my last Report as preparing for the press, and the 

 greater part will undoubtedly be issued during the coming year. 



Appendix A of this Report contains a list of the publications of 

 the Museum issued during the past academic year. We have pub- 

 lished twelve Bulletins in the Zoological Series, making nearly 

 two volumes of the Bulletin. With the exception of one num- 

 ber by Messrs. Scott and Osborne, and three short Bulletins by 

 myself, the publications represent work done in the Zoological 

 Laboratory in charge of Professor Mark. The activity in that 

 Laboratory shows the excellent use which can be made of our 

 publications in bringing out such original work as may be con- 

 sidered worthy of publication by the instructors in the various 

 departments connected with the Museum. 



Among the publications based upon Museum materials, I may 

 mention a Review of the South American Nematognati, by C. H. 

 and Rosa S. Eigenmann, published in occasional papers of the 

 California Academy, I., July, 1890. Nearly the whole of this sys- 

 tematic paper is based upon the collection of Catfishes made by 

 Professor Agassiz during the Thayer Expedition. The authors, 

 with the alacrity with which impracticable plans are so readily 

 laid out for others, needlessly go out of their way to criticise the 

 state of the collection as left by Dr. Steindachner, and give the 

 Museum excellent advice as to what ought to have been done 

 with this collection when it was first brought together. 



Professor W. B. Scott has published in the American Journal of 

 Morphology an extensive paper on the Osteology of Poebrotherium, 

 based in part upon Museum material. 



Professor Osborn has kindly made out for future use of the 

 Museum a list of our desiderata in Western Fossils, both generic 

 and stratigraphic. 



I ought also to mention a short paper on Nettastoma by Dr. 

 Burger, published in a recent number of the Zoologische Jahr- 

 biicher, IV., the material for which was obtained from the Newport 

 Laboratory. 



The additions to our Library show a satisfactory increase in the
