12 Director s Ainiual Report. 



new by Garrett and author's specimens of many of those named by 

 the late Mr. Wm. Harper Pease. These are of course unique and 

 essential to any thorough study of the Poh-nesian mollusk-fauna. 



The work done h\ me was much facilitated by a type-written 

 catalogue of the collection prepared by yourself, without which it 

 is probable double the amount of time would have been required 

 for revision. In the first place I went critically over the colle(5lion 

 species by species to discover ( i ) whether the specific identifica- 

 tions are correct, (2) whether the species are referred to the proper 

 groups, (3) whether any typographical errors occurred on the reg- 

 ister or labels, and (4) whether the group names are those now 

 adopted by naturalists. In general the species appear to be very 

 corre(5lly named, ever3'thiug considered, though the names are not 

 always those in use at present. A small number of typographical 

 errors were detected, but probably no more than would be found 

 in most collecflions thus labelled. 



The most important part of the revision consisted in the sub- 

 stitution of names in current use for others now obsolete but which 

 had been used by Garrett and his correspondents, and the cor- 

 rection of cases where one species had been received from different 

 places and correspondents under more than one name. A good 

 many such cases were found. All these correcflions have been 

 entered in red ink on the regi.ster of the collection except in cases 

 where some more lengthy explanation seemed necessary, in which 

 case notes were made on separate sheets of paper with cross refer- 

 ences to the regi.ster. Similar corrections will be made by me on 

 the copy of the portions of the register which I shall carry to 

 Washington and a skeleton of the classification at present adopted, 

 including families and genera in their natural order, will be re- 

 turned to you as soon as completed. 



With this schedule of groups and the corrections noted to the 

 individual species in the register, the relabelling and rearrange- 

 ment in modern form of the entire collection will be mereh* a mat- 

 ter requiring intelligent clerical work which may be done by au}^ 

 careful person whether acquainted with mollusks or not. I .shall 

 be glad, however, should it facilitate your work, to examine at 

 any time type-written copy intended for the printer so as to elimi- 

 nate any inaccuracies which might creep in. 



I would recommend for the library the purchase of a copy of
