Dr. Packard has visited many parts of the United States and Mexico, 
and has dredged upon the coast of Labrador, in the Gulf of Maine, in 
Massachusetts and Buzzards Bays, off Beaufort, N. C., and upon the 
coast of Florida. 
Iu 1871-’73 he served as State entomologist of Massachusetts, and 
from 1877-’82 was a member of the United States Entomological Com- 
mission. In 1878 he accepted the professorship of Zoology and Geology 
in Brown University, and still retains the position. 
Dr. Packard was elected a member of the National Academy in 1872 
and honorary member of the Entomological Society of London in 1884, 
and at home and abroad a number of societies have elected him to mem- 
bership. 
The entomological writings of Dr. A. S. Packard, recorded in Part I of 
the present list, form but a portion of his contributions to science. His 
memoirs iu other branches in range cover the field of zoology, with 
occasional papers in allied sciences, aud bear testimony alike to his 
versatility and the energy of his mind. 
As a rule only the original place of publication is recorded, though a 
few reprints aud reviews are included, as of possible value in case the 
original is inaccessible. 
Dr. Packard’s contributions to the natural history of Limulus are 
included in the present bibliography, because much of the discussion 
concerning the anatomy, genealogy, &c., of this animal bears directly 
upon the ArcicJmida and other Artliropoda. 
Part II contains a systematic list of the new names proposed by Dr. 
Packard, and I have endeavored to note the collection containing the 
type, but in many cases have been unable to do so. 
A number of the types noted as present in the collection of the 
Museum of Comparative Zoology are, however, in a very poor state of 
preservation, so that a word of explanation should be added. 
The bulk of Dr. Packard’s types were accumulated during his connec- 
tion with, and formed part of the collection of, the Peabody Academy 
of Science at Salem. 
From the year 1880 the Academy was without the services of an 
entomological assistant, so that the collections, u in spite of what care 
could be given them, were rapidly going to ruin,” when, fortunately, in 
1885, their valuable collections of insects were deposited without condi- 
tions in the museum at Cambridge, where their preservation is assured. 
Dr. Packard has aided me throughout the preparation of the list, 
and I am indebted to Messrs. Edwards, Fernald, Hulst, Biley, and Smith 
for assistance in determining the value and position of many of the 
Lepidoptera. Mr. Howard has rendered a similar service with some of 
the parasitic Hymenoptera.
