NO. 3664 MOORE ON THE HIRUDINEA—MEYER 3 
jective even when deeply stirred emotionally. I enjoyed his friendship 
for nearly three decades, during which time we collaborated closely, 
and I shall cherish always my visits with him. 
Moore bequeathed his leech collection and scientific library to the 
United States National Museum, with which he was associated for 
30 years as a Collaborator in the Division of Marine Invertebrates. 
After his death on 1 March 1965, shortly before his 96th birthday, 
I went to Chapel Hill, N.C., where he spent his last years, and to the 
family homestead near Media, Penn., to assist his daughter Elinor 
Moore Irvin in preparing the collection for transfer to the National 
Museum. At the Museum, the large collection, consisting of 2721 lots 
and more than 9000 specimens, was given a preliminary sorting by 
Marian Pettibone and George Ford of the Division of Worms. As a 
result of my interest in the Hirudinea and my close association with 
Dr. Moore, I undertook the task of getting the collection into shape 
for cataloging, in which priority was given to the type-specimens. 
The Moore collection, the most important assemblage of specimens 
of its kind in the world, will serve hirudinologists both here and abroad 
as a reference for systematic studies on leeches. In addition to its 
value for the type-specimens, the collection is important because it 
contains many species from the main faunal regions of the world. 
While most of the identifications of this material were made by Moore 
there are numerous specimens identified and contributed by his con- 
temporary workers abroad, viz., C. Badham, Australia; R. Blanchard 
and E. Brumpt, France; E. Caballero y C., Mexico; W. A. Harding 
and K. H. Mann, Great Britain; L. Johansson, Sweden; T. Kaburaki 
and A. Oka, Japan; R. Ringuelet, Argentina. 
Some of the type-specimens of the Moore species-group had already 
been returned to the institutions supplying the material, and some 
had been set apart from the general collection but retained by Moore. 
Some of the type material, however, including paratypes and syntypes 
(often referred to as cotypes), had not been returned to the suppliers, 
nor had it been set apart from the general collection by Dr. Moore. 
In extracting the type-specimens from the general collection, I have 
been guided by the data given in the original references. 
The purpose of this paper is to indicate the change in the location 
of the Moore material, not already deposited in museums, from his 
private collection to the U.S. National Museum; to verify the presence 
of type-specimens previously deposited in museums in America and 
abroad; and to provide relevant information on the type-specimens 
for the benefit of interested future workers. 
A search was made to locate as many of Moore’s type-specimens 
as possible. For the most part this was done by corresponding with 
the institutions where types had been deposited, as stated in relevant
