Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, 1905, Vol. 47

This material was collected over a wide range of territory, including the whole extent of the Pacific coast of North America from Panama to the Aleutian Islands, northward through the Bering Straits far up into the Arctic Ocean, and westward to the Commander Islands off the coast of Kamchatka. It includes both shore collections and dredgings off the coast to a depth of several hundred fathoms.

The following collections comprise the bulk of this material: -

1. A small collection from Panama and the coast of California, made many years ago by Mr. Alexander Agassiz, and now the property of the Museum of Comparative Zoology, Harvard College.

2. A small collection belonging to the Peabody Museum, Yale University, made by Mr. F. H. Bradley at Panama.

3. Very extensive collections made by the U.S. Fish Commission Steamer Albatross along the whole west coast of North America during the years 1888 to 1895. These collections include a few forms collected on shore at low water, although the great bulk of the material was dredged at various localities off the coast at depths ranging from a few to several hundred fathoms. The greatest depth at which nemerteans were collected was 414 fathoms, the greater number being taken in less than 60 fathoms. Several very interesting forms presenting anatomical peculiarities adapted for life at considerable depths of water are included in these collections, and are described on the following pages. A single species of pelagic nemertean (Planktonemertes agassizii Woodworth) was taken at the surface in the equatorial regions. An individual of another species (Euborlasia maxima) measures 45 mm. in width after preservation, and probably exceeds in bulk any other known species.

4. Collections made in 1882 by the Point Barrow Relief Expedition to Northern Alaska and the Arctic Ocean.

5. Collections, drawings, and notes made by Mr. B. B. Griffin in Puget Sound and Southern Alaska, while a member of the Columbia University expeditions in 1896 and 1897. The death of this enthusiastic young investigator occurred while engaged in the study of these specimens.
