forgotten, and, I am happy to say that it is in a good state 

 of progress, about one-third of our species having been 

 critically reexamined and carefully identified by all the means 

 in our possession, and arranged after an improved method 

 for reo:istrv in a book which has Ions: been waitins: for the 

 purpose. We still, however, need several books for the 

 proper identification of species, and hope that before another 

 year is completed we may rejoice in the possession of more 

 ample means of conchological identification. 



During the year we have packed and sent away 32 boxes, 

 containing 3,890 species and 21,109 specimens. As evinc- 

 ing our ability to furnish our correspondents with species 

 called for, I may mention that to one person we sent 900 

 species of terrestrial and marine shells alone, the recipient 

 having expressly excluded fluviatile species altogether, and 

 also species from Europe, India or Australia, so that our 

 range of duplicates may fairly be set down as not less than 

 1,400 or 1,500 species. 



Report on the Alcoholic Mollusca^ by J. Henry Blab:e. 



During the past year not much has been done with this 

 collection besides continuing the systematic arrangement, 

 keeping everything in a safe condition. Although the 

 arrangement for convenience, begun last year, is not fully 

 completed, the collection is nevertheless in a condition easily 

 accessible. 



Many of the specimens contained in jars with cork stoppers 

 were changed to glass-stoppered jars. 



The many collections of mixed specimens which have re- 

 mained in this condition for a long time, have been assorted, 

 with a few exceptions, and the species properly labelled. 



Donations for the year are : — 



Mr. Henry Hemphill, a collection from San Diego. 



Dr. M. H. James, 306 species from Honolulu. 



Mr. J. Ball, 17 specimens from Texas. 



Capt. P. C. Johnson. U. S. N., 150 specimens, California. 



Dr. Henry Stanley Pitkin, U. S, N., 1 octopus^ Honolulu, S. I.
