498 PROCEEDINGS OP THE ACADEMY OP [1881. 



REPORT OF THE PROFESSOR OF INVERTEBRATE 

 PALEONTOLOGY. 



The Professor of Invertebrate Palaeontology respectfully reports, 

 that during the year 1881, a course of 26 lectures on Invertebx'ate 

 Palaeontology was delivered in the class room of the Academy 

 (commencing on March 8, and terminating June 4), which course 

 was attended by an average of about 25 listeners, largely made up 

 of teachers from some of the more prominent institutions of 

 learning in the city. 



The work of classifying and arranging the old collections in the 

 Palajontological Department of the Academy has made some pro- 

 gress during the year. The determination of specimens embraces : 



123 trays of (so-called) Cretaceous fossUs from the Tejon 

 group of California, originally described by W. M. 

 Gabb for the Whitney Survey, and largely composed 

 of type specimens; these last have been specially 

 indicated. 



312 trays of Tertiar}^ (Miocene and Pliocene) fossils, 

 largely composed of T. A. Conrad's t^^pes. 



435 



The specimens contained in 263 of these trays have been care- 

 fully mounted and labeled by Mr. Chas. F. Parker, Curator-in- 

 charge; to the remaining 172 trays, only provisional labels have 

 been attached. 



The Pala^ontological collections of the Academy have thus far 

 suffered greatly from want of room for their proper exposition ; 

 something toward remedying the evil, by the construction of 

 additional drawers, has been done in the course of the year, but 

 much more still remains to be accomplished. It is especially 

 desirable that a suitable cabinet, or other fixture, be obtained for 

 the exhibition of specimens typically representing the various 

 geological formations, which would not only greatly facilitate the 

 work of the Professor in teaching, but would very materially aid 

 the students, special as well as general, in their studies. 



All the additions to the Pateontological collection, made in the 

 course of the year, have been labeled and mounted by Mr. Chas. 

 F. Parker, Curator.
