32 Director's Annual Report. 
‘‘Besides short collection trips on Oahu, two visits were made 
to Molokai during February and March, and one to Maui. ‘Those 
to Molokai were especially to study the fossil beds along the north- 
ern shore of the island and if possible to collect representative 
series from each of the beds. ‘These occur along almost the whole 
northern coast line from Puukapele to the extreme northwestern 
point, a distance of about twelve miles as the crow flies. About 
two miles of coast line have not been visited up to the present time, 
and some of the localities will have to be searched over again as 
the recent heavy rains have undoubtedly uncovered new surfaces 
of the deposits. 
‘The trip to Maui was very successful from the collecting 
standpoint. Of fresh specimens, 7,793 were collected in about 
three weeks, and in addition 955 fossil shells. 
‘“Three large series of shells came to the Museum from Hawaii 
during the year, collected by Messrs. Forbes, Thurston and 
Gouveia. 
‘‘A number of the fossil shells have to be specially prepared 
before they can be studied. Shells that are found in earth are 
boiled in a solution of Pear’s soap and syringed. ‘The result isa 
clean shell which in numerous instances shows the original color 
pattern. Specimens found in lime sand and earth deposits have 
to be carefully cleaned with dental tools before they are fit for 
study. The labor involved in preparing fit museum specimens of 
fossil material is usually much more than when the specimens 
are alive. 
‘‘Of the remarkable species turned in during the year I will 
only mention three or four. Mr. Thurston has discovered a new 
species of Amastra on the island of Hawaii, which is the largest 
species of this genus recorded from this island. He also obtained 
two living typical specimens of Leptachatina tenutcostata Pse., 
which, so far as I know, are the only typical living examples of 
this species taken since it was discovered by Pease. 
‘‘Mr. Forbes found a remarkable new species of Sphyradium 
and one of Aadiella on the island of Hawaii which are entirely 
unlike any other species from our islands. 
‘“Mr. Thurston and Mr. Gouveia each found a fragment of a 
new species of Amastra. Both fragments agree rather closely and 
the species belongs to the group of Amastra spherica. The
