1886.] 309 [Annual Meeting 



The principal accession of the year has been the very fine collec- 

 tion of North American lichens given by one of our oldest and 

 most highly honored members, Mr. Charles J. Sprague. This col- 

 lection has been properly catalogued by Miss Carter and a special 

 report by Dr. Farlow was prepared and read at a recent meeting of 

 the society. The collection contains 2635 specimens, representing 

 78 genera and 849 species and varieties. Many of these are very 

 rare and valuable additions to the Herbarium. 



Comparative Anatomy. 



Mr. Henshaw has made, with materials given by several per- 

 sons, a few alcoholic and forty osteological preparations of reptiles, 

 birds, carnivora and monkeys. 



Dr. D wight has presented a few sections of the long bones of va- 

 rious mammals prepared from materials lent him by the society. 

 Mr. Henshaw has begun the mounting of the sea lion given some 

 years since by Capt. Charles Bryant. 



Sponges. 



Miss Martin has worked over and labelled all the materials not 

 on exhibition. Preliminary work upon the Keratosa of the Bermuda 

 collection has been completed, and it is expected that the whole 

 Bermuda collection can be finished and got out of the way next 

 year. 



Mollusea. 



Mr. Henshaw and Miss Martin have made considerable progress 

 in the identification of the genera, and labelling of the miscellane- 

 ous materials in this department. 



During the progress of this work the exhibition collection has 

 been modified in order to admit a more extended series of forms. 



This work will be completed, and a final report made next year. 



Insects. 



Dr. S. W. Williston has named and returned our collection of 

 Asilidae and Tabanidae. While engaged in the work of collecting 

 materials for the Teachers' School of Science, Mr. Henshaw was 

 able to obtain between five and six hundred specimens of value to 

 our Museum from New England, Florida and Texas. These have 

 been labelled, and about two-thirds have been identified. 



Mr. Edward Burgess has presented his general collection of in- 

 sects, which will be reported upon next 3 T ear, and also some al-
