revised and prepared for labelling with printed labels by- 

 Mr. Van Vleck, and a similar work is being clone by the Cus- 

 todian for the Poriferae. 



Dr. W*K. Brooks continued his work in the Mollusean 

 Department upon the models of the animals, which I partic- 

 ularly described in my last report, and succeeded in com- 

 pleting in all fourteen models, twenty-seven anatomical 

 preparations and nine explanatory outline drawings. Dr. 

 Brooks also completed the rearrangement of the shells now 

 in the Museum, according to the plan so often described in 

 these reports. The distribution and arrangement of the alco- 

 holic collection was also begun, but could not be completed 

 for want of bottles. 



In October, Dr. Brooks, who had proved himself, by these 

 and other works, a most valuable and desirable assistant, 

 removed to Baltimore, having been appointed Assistant Pro- 

 fessor in the Johns Hopkins University. The work upon this 

 Department was continued under the charge of Mr. Yan 

 Vleck, who reports that about one-third of the collection on 

 exhibition has been relabeled by Miss Washburn, with printed 

 labels. Dr. P. P. Carpenter of Montreal, has continued the 

 work of identification, and has completed a large proportion 

 of the terrestrial shells. 



The Articulata have all been rearranged by Mr. Henshaw, 

 and the same gentleman, who has had charge of the Insects, 

 reports that the New England Collection of Coleoptera has 

 been completed, and the Neuroptera, Orthoptera, Hymenop- 

 tera, and Lepidoptera rearranged. Very important additions 

 to the collection of Coleoptera have been made from the 

 collection of the late Mr. Sprague, who will be remembered 

 as an able assistant and earnest worker in our Museum. 

 We have been permitted, in accordance with the verbal 

 request of its late owner, to select therefrom every specimen 

 of value to our collection. These additions, amounting to 

 600 species and 2000 specimens, and late advances in knowl- 

 edge in this Department, have made it necessary to revise
