lo Director's Aiuiua/ Report. 



specimen of this species is in the collection of the Academy of 

 Natural Sciences of Philadelphia, and is without locality. 



"(^n Oahu the fossil pocket found by Mr. Thaanum has been 

 mentioned. The two most remarkable species are a large un- 

 described species of Amastra and a species of Endodonta of au 

 entirely new type. The latter ma>- be the representative of a 

 new sub-genus. 



"Also from Oahu, Amastra antiqiia and Amastra vetusta 

 were rediscovered. The original material was found by Dr. Lyons 

 and described by Mr. Baldwin. Neither of these species was in 

 the colle(5lion .of the Museum until your Curator found them this 

 year. Repeated search has been made to relocate the original 

 beds, but so far unsuccessfully. The finding of both these spe- 

 cies in new beds is interesting. 



"On Molokai Mr. Hitchcock found the base of what appeared 

 to be an entirely new species of Amastra. Three trips were taken 

 in the hope of finding whole specimens, all of which were un- 

 successful. In December Mr. G. P. Cooke sent to the Museum 

 specimens which probably belong to this species, which is the 

 largest species of land shell from any of our islands if we except 

 Kauai; one specimen is nearly 40 mm. in length. 



"The monograph on the Hawaiian Endodontidce has received 

 considerable attention during the year and a portion of the manu- 

 script has been written. One hundred and four forms have been 

 photographed b}' Mr. Baker, and about forty additional forms will 

 be illustrated. More than one hundred species and varieties of 

 this interesting family are in our collection which are distributed 

 over several hundred catalogue numbers. Mr. Sykes, in 1901,. 

 recognized only twenty-one species, and since then about ten have 

 been added. Only nine species of this genus were collected by 

 Mr. Perkins. The work of finishing this monograph will take con- 

 siderable time, as hardh' a month passes without the finding of 



some new and interesting varietv or species."
