The most notable special collections are the Horn and Wilt collec- 
tions of Coleoptera; the Martindale and Skinner collections of Tepid op- 
tera; the Calvert collection of Neuroptera (on deposit); the Osten- 
saken cotypes of Diptera; the Cresson and Bassett collections of

The collection of Mollusks numbers over 100,000 trays and more 
than 1,500,000 specimens. Of this number 40,000 trays have been 
catalogued and numbered as new accessions since 1893. The older 
collection consists of the original collection of the Academy, begun 
about 1817 by Thomas Say; the Robert Swift collection of West Indian 
shells, about 10,000 specimens; the A. D. Brown collection of land 
shells, bequeathed to the Academy in 1887, 5,400 trays. About 
10,000 trays of these collections have been catalogued and numbered. 
The alcoholic collection of Mollusks consists of about 6,000 lots, 
probably over 75,000 individual specimens. The number of types 
of Say, Conrad, Try on and others is not known, but since the year 
1901, 925 types have been described from the new material received. 
Other invertebrates number about 11,500 specimens, of which 4,000 
are Crustacea and 2,800 worms. The most important collections are 
the Guerin collection of Crustacea, the H. C. Chapman collection of 
Marine Invertebrates from Naples and the Edward Potts collection of 
fresh-water sponges. 
The Herbarium contains about 584,000 specimens of flowering plants 
and ferns, comprising among others the collections of Muhlenberg
