io Director' s Antiual Report. 



"Our exchanges with the three institutions mentioned in the 

 last report have continued with satisfaction on both sides. The 

 additions to the herbarium are shown in the list of accessions. 



"The conveniences for arranging the herbarium have been 

 greatly improved by the addition of new cases in the basement, 

 formerly the Director's room. The arrangements for work or for 

 showing specimens to visiting workers in botany are nearly perfect . ' ' 



Pulttionata. I quote from the Curator's report to me : 

 "The year 191 1 has been the most satisfactory, in the amount 

 of work accomplished on our Hawaiian land shells, of any since 

 the Curator has been connected with the staff of the Museum. 

 For the first time the collection is really accessible for stud}-. 

 Before the occupancy of the laboratory the collection was stored 

 in four different parts of the Museum. The trays were piled in 

 cases and on the floor of one of the alcoves of the third floor of 

 Hawaiian Hall, and a good deal of the material had to be kept at 

 the home of the Curator for study during the greater part of the 

 time. Now, with proper cases, shelves, work tables and a sink, 

 the Curator can get at and has handy whatever specimens or ap- 

 paratus he may need. Probably half again or twice as much work 

 has been accomplished this year, due for the most part to the time 

 saved in getting at whatever has been needed. The moving of 

 the collection from different parts of the Museum, and the partial 

 arrangement of the same have taken up a great deal of the Cura- 

 tor's time during the year. 



"At present the genera Philonesia, Endodonta, Mesopupa, 

 Lyropupa, Amastra, Carelia, Leptachatina, Auriculella, Torua- 

 tellina, Succinea and several other genera with from one to four 

 species, are arranged in the cases. Our collection of the genera 

 of Auriculella, Carelia and Endodonta is fully arranged and classi- 

 fied according to species and distribution, and at present only the 

 labels have to be written and placed in the trays. This will 



necessitate the writing of about 1000 to 1500 labels.
